Opis:
Agrobacterium tumefaciens EHA101 (pTd33) strain carrying uidA (GUS) reporter gene was used in model experiments on roseroot callus transformation. The T-DNA of pTd33 binary vector plasmid harbors nptII gene conferring resistance to kanamycin, and a uidA reporter gene, encodes the ß-glucuronidase enzyme. Roseroot seeds were sterilized and germinated on half strength MS media of which 70% germinated without any pretreatment. Calli were obtained from leaf segments of the in vitro grown seedlings. Calli was grown on solid MS medium supplemented with 1 mg l⁻¹ NAA and 0.5 mg l⁻¹ BAP. Different types of calli were obtained of which the green and compact type was chosen for transformation experiments. After co-cultivation with agrobacteria, calli were transferred to the same medium supplemented with 20 mg l⁻¹ kanamycin, 200 mg l⁻¹ carbenicillin and 300 mg l⁻¹ claforan with antioxidants (Polyclar and DTE) for selection. GUS test using a titron buffer was applied for monitoring the transformation of the calli. DNAs of 20 individual samples was extracted and subjected for PCR analysis proved the stable transformation in all of the taken samples by amplifying the nptII gene fragment. The method introduced here can be a tool for inserting and over-expressing the genes encoding for hypothesized enzymes to be involved in the biosynthesis of pharmaceutically important bioactive molecules of roseroot and therefore facilitating the applications for callus culture of roseroot in different bioreactor systems for pharmaceutical productions.
Szczep Agrobacterium tumefaciens EHA101 (pTd33) przenoszący gen reporterowy uidA (GUS) został użyty w modelowych doświadczeniach nad transformacją kalusa różeńca górskiego. T-DNA z plazmidy wektora binarnego pTd33 mieści w sobie gen nptII przekazujący odorność kanamycynie, natomiast gen reporterowy uidA koduje enzym ȕ-glukuronidazy. Nasiona korzenia różeńca gorskiego wysterylizowano i poddano kiełkowaniu na połowie zestawu pożywki MS. Spośród nich 70% wykiełkowało bez żadnego wcześniejszego zabiegu. Kalusy otrzymano z segmentów liści sadzonek wyrosłych in vitro. Kalusy wyhodowano na stałej pożywce MS z dodatkiem 1 mg l⁻¹ NAA oraz 0,5 mg l⁻¹ BAP. Uzyskano różne typy kalusa, z których typ zielony i zwarty zostaá wybrany do doświadczeĔ dotyczących transformacji. Po wspólnej hodowli z agrobakteriami kalusy byáy przeniesione to tej samej pożywki uzupełnionej 20 mg l⁻¹ kanamycyny, 200 mg l⁻¹ karbenicyliny oraz 300 mg l⁻¹ klaforanu z przeciwutleniaczami (Polyclar i DTE) do selekcji. Zastosowano test GUS przy użyciu bufora trytronowego do monitorowania kalusów. Wyodrębniono 20 indywidualnych próbek DNA i poddano je analizie PCR, która wykazała stabilną transformację we wszystkich próbkach poprzez amplifikowanie fragmentu genu nptII. Metoda przedstawiona tutaj może być narzędziem insercji i ekspresji kodowania genów do hipotetycznych enzymów, które mają brać udział w biosyntezie ważnych z punku widzenia farmaceutycznego molekuł różeca górskiego, co ułatwi zastosowanie hodowli kalusów różeńca górskiego w różnych systemach bioreaktorów w produkcji farmaceutycznej.

Opis:
Shoot-differentiating callus culture of Ruta graveolens ssp. divaricata (Tenore) Gams was maintained on four variants of Linsmaier-Skoog (L-S) medium containing different concentrations of plant growth regulators, 1-naphthaleneacetic acid and 6-benzylaminopurine, ranging from 0.1 do 3.0 mg/l. Methanolic extracts of biomass cultured in vitro were used to determine the contents of free phenolic acids with an HPLC method. Out of eight compounds under analysis, six were shown to be present in the samples: caffeic acid, chlorogenic acid, p-coumaric acid, p-hydroxybenzoic acid, protocatechuic acid and syringic acid. Total contents of the compounds under study ranged from 124.9 to 138.7 mg/100g d.w., depending on the L-S medium variant. p-Coumaric acid was the main compound in the extracts from biomass cultured on all tested medium variants and its amounts were interesting from practical perspective (97.3-112.9 mg/100g d.w.). This compound was isolated, purified and its identity was confirmed by spectral methods. The contents of other compounds did not exceed 11.1 mg/100g d.w. Extracts of the above-ground parts of plants growing in vivo (stems, leaves, herb), analyzed for comparison, contained three phenolic acids: protocatechuic acid (52.0-88.2 mg/100g d.w.), vanillic acid (2.6 – 17.8 mg/100g d.w.) and trace amounts of syringic acid. This is the first report on the effect of growth regulators on the accumulation of free phenolic acids in biomass of R.graveolens cultured in vitro. This is also the first report documenting the isolation of p-coumaric acid from biomass of this subspecies cultured in vitro and also from any plant in vitro culture. In addition, for the first time in the above-ground parts of the plants growing in vivo phenolic acids were analyzed.

Opis:
Callus was inducted on wounded leaf explants from shoot tips of a particular Prunus domestica 'Węgierka Zwykła' clone cultivated in vitro. The improvement of Sweet Common Prune stock callus tissue parameters has been approached by experiments on culture protocols. Either for the induction or maintenance of tissue modified Murashige and Skoog medium, supplemented with different auxins and cytokinins at varying concentrations, was used. The goal was to obtain the highiest possible proliferative capacity of friable tissue without any signs of cell redifferentiation for about 10 weeks. The choice of auxin was an important factor regulating the rate and kind of tissue growth, and for the examined prune clone auxin alone brought a relatively small proportion of cells into division, so advantageous was to combine it with oxygenated cytokinin. Friable tissue was obtained on media supplemented with dicamba or with picloram, but not with 2.4-D neither alone nor combinated with IBA.

Opis:
The purpose of our investigation was to determine appropriate conditions for induction of raspberry (Rubus idaeus cv. Nawojka) cell suspension culture. The established callus culture obtained from leaf explants was used as an inoculum for cell culture initiation. Five combinations of plant growth regulators: 1) 4.0 mg l-1 IAA and 1.0 mg l-1 BAP; 2) 0.25 mg l-1 2,4-D; 3) 0.5 mg l-1 2,4-D; 4) 2.0 mg l-1 NAA and 2.0 mg l-1 BAP; 5) 4.0 mg l-1 NAA and 2.0 mg l-1 BAP, added into modified Murashige and Skoog (1962) medium, were tested in order to get the callus culture suitable for initiation of a cell suspension. The best callus (vigorously growing, healthy and friable) was obtained on the medium supplemented with 4.0 mg l-1 IAA and 1.0 mg l-1 BAP. To find the appropriate culture conditions for dispersing callus tissue in liquid medium into single cells and small aggregates, four combinations of plant hormones (auxins and cytokinins) were tested. The best culture medium for induction of raspberry cv. Nawojka cell suspension appeared to be the one supplemented with 1.0 mg l-1 2,4-D. Also the medium with 8.0 mg l-1 IAA and 1.0 mg l-1 BAP was similarly efficient.
Celem prezentowanych badań była optymalizacja warunków kultury in vitro umożliwiających uzyskanie zawiesiny komórkowej maliny (Rubus idaeus L.). Jako inokulum do zainicjowania kultury zawiesinowej zastosowano ustabilizowaną kulturę kalusa uzyskaną z eksplantatów liściowych na zmodyfikowanej pożywce wg Murashige i Skooga (1962). W pierwszym etapie badań testowano 5 kombinacji regulatorów wzrostu (auksyn i cytokinin) dodawanych do pożywki stymulującej powstawanie tkanki kalusowej, w celu uzyskania kultury kalusa odpowiedniej do indukcji zawiesiny komórkowej. Najlepszą tkankę kalusową (szybko mnożącą się, o luźnej strukturze) uzyskano w kombinacji uwzględniającej uzupełnienie pożywki do kultury in vitro auksyną IAA w stężeniu 4,0 mg l-1 oraz cytokininą BAP w stężeniu 1,0 mg l-1 . W drugim etapie badań testowano warunki kultury in vitro umożliwiające odpowiednią dyspersję tkanki kalusowej w płynnej pożywce, skutkującą uzyskaniem populacji pojedynczych komórek oraz małych agregatów komórkowych w hodowli. W tym celu testowano 4 warianty składu pożywki, różniące się rodzajem i stężeniem zastosowanych hormonów roślinnych należących do klasy auksyn i cytokinin. Najlepszy wynik uzyskano w płynnej pożywce uzupełnionej syntetyczną auksyną 2,4-D w stężeniu 1,0 mg l-1, także pożywka zawierająca auksynę IAA w stężeniu 8,0 mg l-1 oraz cytokininę BAP w stężeniu 1,0 mg l-1 dała dobry wynik.

Opis:
Several aspects of in vitro culture have potential for cereal improvement. This paper focuses on evaluation of somaclonal variation (SV) from immature embryo callus culture, and doubled haploid (DH) production via anther culture in barley. Genetically stable SV was observed for several seedling morphological traits such as albino, yellow, light green and lethal. SV occurred at approximately half the frequency of azide-induced mutagenesis. The potential for widespread application of anther culture-mediated DH production in barley breeding and genetic studies was increased through culture procedure improvements and understanding the inheritance of anther culture response. Methodology improvements included substitution of inexpensive gelrite for expensive ficoll or agarose, ability to grow anther donor plants under field as well as growth chamber conditions and flexibility in cold pretreatment/storage of anther donor spikes for 4-6 weeks prior to anther plating. From diallel analysis, inheritance of anther culture response was complex with additive and dominance effects for embryoid formation, total plant regeneration and green plant regeneration and reciprocal effects (maternal) for green plant regeneration. High x low responder crosses generated F₁’s that were intermediate in response and low x low crosses sometimes produced F₁ heterosis for green plant regeneration. Therefore, some recalcitrant types appear to be usable in anther culture DH production systems within a breeding program.

Opis:
Twenty field-grown genotypes of diploid Italian ryegrass (Lolium multiflorum Lam., 2n = 2x = 14) were tested for their ability to induce callus and regenerate plants. Callus cultures were initiated from segments of immature inflorescences cultured on the MS medium supplemented with 4.0 mg L⁻¹ 2,4-D. The calluses were subcultured first on the maintaining medium (MS medium with 2.0 mg L⁻¹ 2,4-D) and later on the rooting medium (MS medium with 0.2 mg L⁻¹ 2,4-D). The frequency of callus induction varied depending on the source of explant and the initial genotype. A total of 473 green plantlets were regenerated, of which 420 were established in the soil. All these plants had the morphological characteristics of Italian ryegrass. Among 372 regenerants analysed cytologically, 302 (81.2%) had the expected diploid chromosome number (2n = 2x= 14), 65 (17.5%) were tetraploid (2n = 4x = 28); several aneuploids and mixoploids were also observed. All diploid and tetraploid regenerants were male and female fertile. However, a great variation of female fertility within and between both groups of regenerants was observed.

Opis:
The aim of the study was to induce somaclonal variability in the callus culture of L. hirsutum f. typicum and L. chilense and to characterize them in respect to tolerance to salinity. Callus was initiated on the cotyledon fragments grown on the medium supplemented with NAA and BAP. The tolerance of callus to salt was tested on MS media containing NaCl in concentration 25, 50, 75, 100, 200 mM. Callus tolerant to 100 mM NaCl was next regenerated by ten weeks on the media with different doses of growth regulators. After this time genetic differences between selected fragments and control (MS medium containing no growth regulators) were determining using ISSR-PCR method. The results show that NaCl concentration significantly affects the regeneration of callus in L. hirsutum f. typicum and L. chilense. The dose 200 mM NaCl of the medium results, in both species, in callus dying. Comparing the genetic similarity of examined callus samples with the control ones in both species, it may be stated that the differences in their response to NaCl and applied growth regulators were generally in the range 2–30%.
Celem pracy była próba indukowania zmienności somaklonalnej w kulturach kalusowych L. hirsutum f. typicum i L. chilense oraz charakterystyka ich tolerancji na zasolenie. Kalus inicjowano na fragmentach liścieni wyłożonych na pożywkę uzupełnioną NAA i BAP. Tolerancję na zasolenie badano, wykładając fragmenty kalusa na pożywkę uzupełnioną 25, 50, 75, 100, 200 mM NaCl. Kalus uznany za tolerancyjny był regenerowany na pożywkach uzupełnionych różnymi kombinacjami roślinnych regulatorów wzrostu. Następnie metodą ISSR-PCR określono różnice genetyczne pomiędzy wybranymi fragmentami kalusa a kontrolą. Na podstawie otrzymanych wyników badań stwierdzono, że stężenie NaCl w sposób istotny wpływa na regenerację w przypadku obu badanych gatunków. Stężenie 200 mM NaCl powoduje zamieranie tkanki kalusowej. Obserwowana u obu gatunków pomidora na poziomie kalusa tolerancja na zasolenie NaCl jest prawdopodobnie w większości przypadków zmiennością dziedziczną.

Opis:
We investigated direct and indirect formation of somatic embryogenesis in Brassica oleracea var. botrytis (cauliflower), a very important vegetable crop worldwide. Direct somatic embryogenesis, which is rather rare, was achieved in culture of 2-week-old hypocotyl explants of Brassica oleracea var. botrytis on MS medium supplemented with 1.0 mg/l 2,4-dichlorophenoxyacetic acid (2,4-D) and 0.5; 1.0; and 1.5 mg/l kinetin. Initial induction of embryogenic callus was achieved on MS supplemented with very low concentrations of 2,4-D (0.05 mg/l and 0.1 mg/l). Indirect somatic embryogenesis from leaf sections was obtained on MS supplemented with 0.05 or 0.1 mg/l 2,4-D. We examined various stages of somatic embryos (globular, heart, torpedo, cotyledonary). More embryos per explant were produced through the indirect pathway (23–25) than through the direct pathway (14–19). The number of embryos produced was high. There is a potential for recurrent, repeated or secondary somatic embryogenesis, possibly an unlimited source for mass propagation and ideal for synthetic seed production in this species. Plant regeneration was achieved on half-strength MS medium without any hormones.

Opis:
Effect of auxins: (NAA, IAA), cytokinin BAP and culture conditions (light, darkness) on callus induction in cotyledons of tomato cultivar ‘Maskotka’ and the wild form of Lycopersicon peruvianum was investigated. Callus was obtained in all experimental combinations, except of the culture with L. peruvianum on the medium with 1.0 mg⋅dm⁻³ of IAA. Callus weight, colour and structure depended on the tomato genotypes and experimental conditions. Best medium for the culture of tomato cultivar ‘Maskotka’ and the wild form L. peruvianum proved to be MS medium supplemented with 2.0 mg⋅dm⁻³ of IAA and 1.0mg⋅dm⁻³ of BAP.
W pracy określono wpływ auksyn (NAA i IAA) i cytokininy BAP oraz warunków kultury (światło, ciemność) na tworzenie się kalusa na liścieniach odmiany uprawnej pomidora ‘Maskotka’ oraz formy dzikiej Lycopersicon peruvianum. Indukcję kalusa obserwowano u obu badanych form niezależnie od składu hormonalnego pożywki, za wyjątkiem kombinacji, z auksyną IAA w ilości 1.0 mg⋅dm⁻³. Masa, zabarwienie i struktura otrzymanego kalusa zależały od genotypu badanych form pomidora oraz od warunków prowadzenia kultury. Inicjacja kalusa pomidora odmiany ‘Maskotka’ i L. peruvianum powinna odbywać się na pożywce MS uzupełnionej 2,0 mg dm⁻³ IAA i 1,0 mg dm⁻³ BAP.

Opis:
The research was conducted on explants of silver fir (Abies alba Mill.) deriving from several forest districts in southern Poland. The study encompassed the influence of the origin of plant material, type of explants, kind of substances used for explants sterilization, PPM and the type of medium on the ability to form embryogenic callus and to develop somatic embryos in silver fir explants. From the plant material collected in three sites, 57 clones were obtained from mature zygotic embryos; this produced an embryogenesis frequency of 6%. Embryogenic callus was obtained with a diameter of 65–70 mm depending on the material origin. The best medium for development of callus inducted on embryos isolated from mature silver fir seeds was the SH medium. Somatic embryos were formed in a globular stadium (24 pieces) on this medium. The 10% solution of NaOCl (used for 15 minutes) turned out to be the most effective substance for seed sterilization.

Opis:
Goldenrod (Solidago canadensis L.) is an invasive plant species in many countries except North America but a cut-flower species worldwide. There is a need to generate and propagate goldenrod clones efficiently for research and commercial purposes. A callus induction and plantlet regeneration system was developed by studying the influence of explant type and different concentrations of plant growth regulators. The highest callus production from leaf segments was obtained on Murashige and Skoog's medium (MS medium) supplemented with 1.0 mg/L naphthalene acetic acid (NAA) and 1.0 mg/L 6-benzylaminopurine (BA). Adventitious shoots could be regenerated directly from leaf explants without an intermediate callus phase with the highest shoot induction percentage of 87.2%. The largest number of adventitious shoots per leaf explant (3.2) was obtained on MS medium supplemented with 0.4 mg/L NAA and 2.0 mg/L BA. MS medium supplemented with 0.1 mg/L NAA and 1.0 mg/L BA was the best medium for axillary shoot regeneration from nodal segments. The highest root number and longest roots occurred on half-strength MS without the addition of any growth regulator. Rooted plantlets were then transferred to a soil-based growth medium, placed in a greenhouse, and acclimatized with 100% success. All surviving plants grew normally without showing any morphological variation when compared to those grow from seed. This regeneration protocol may be used to produce certain biotypes of goldenrod suitable for genetic transformation, rapid propagation of goldenrod for commercial purposes or for screening fungi and toxins as potential biocontrol agents against this weed.

Opis:
The influences of genetic and environmental factors on the anther culture responses of wheat were investigated. Significant differences for callus induction, plant regeneration, and green plant percentages were observed when the nucleus of Triticum acstivum L. cv. Selkirk was transferred to ten alien cytoplasms by substitution backcrosses. In most cases, the alien cytoplasms decreased anther culture responses, but sometimes they were as good as or better than the T. aestivum cytoplasm. Significant within-genotype variation for anther culture responses were observed for wheat varieties Chris, Yecora Rojo, WA7176 and Edwall, indicating genetic heterogeneity in the present commercial cultivars, and potential for improving anther culture responses by in vitro prescreening. When five genotypes (Chris, Pavon 76, Butte 86, WA6916, and Edwall) were cultured across three (potato-4 liquid, 100 g L⁻¹ ficoll-supplemented, and 6 g L⁻¹ agar-solidified) induction media, the liquid and ficoll-containing media were 10 to 15 times more productive than the agar-solidified medium. Whereas, the ficoll medium was not significantly different from the liquid medium. Several low concentration starch media appeared promising to replace current induction media. The starch media sustained the highcallus-induction properties of the liquid medium, while improving callus aeration similar to that observed on solid media, resulting in markedly higher plant regeneration and green plant percentages.

Opis:
Leatherleaf Chamaedaphne calyculata (L) Moench is a relict, rare and endangered species in Poland. There are no reports on the micropropagation of Chamaedaphne calyculata in the literature. Therefore, the aim of this study was to propose a propagation protocol for leatherleaf via indirect organogenesis using leaves and stems (internodal segments) derived from mature plants growing in a natural stand and from plants grown in vitro as explants. The medium developed by Anthony et al. (2004) with 100%, 50% and 25% salt concentrations, supplemented with IAA (5 and 10μM) and TDZ (5 and 10μM), was used for callus development and the induction of adventitious shoots. The media developed by Anthony et al. (2004) and Anderson (1980), both containing 10μM TDZ and 5μM IAA or 2.28μM zeatin, were used for adventitious shoot elongation. Secondary explants proved to be the most effective starting material for callus induction, the regeneration and elongation of adventitious shoots. The most supportive medium for callus induction and growth and the induction of adventitious shoots was the full medium proposed by Anthony et al. (2004) containing 5μM IAA and 10μM TDZ. Anderson’s (1980) medium containing 2.28μM zeatin delivered optimal results in the elongation of adventitious shoots of Ch. calyculata. Roots were cultivated on Anderson’s (1980) phytohormone-free medium. Approximately 65% of the plantlets survived after transfer to the sphagnum-peat and perlite mixture (3:1). The plants grew normally without any signs of morphological variation. This study makes the first ever attempt to propose an effective micropropagation protocol for Ch. calyculata.

Opis:
In vitro flowering and micropropagation are useful for plant breeding programs and commercial production of important ornamental plants. In vitro conditions including media components, kind, concentration and ratio of plant growth regulators and culture conditions significantly affect in vitro flowering and micropropagation. There is no any report dealing with the in vitro flowering of Lisianthus (Eustoma grandiflorum). Here, a protocol was developed for flowering and high frequency in vitro micropropagation of E. grandiflorum, an ornamental plant. Micropropagation is an effective tools for propagation of ornamental plants in large scale. The aim of the present study was to evaluate the effect of different concentrations of NAA and BA on micropropagation and flowering of Lisianthus, in vitro. Used culture medium was MS enriched with 0, 0.1, 0.2 and 2 mg L-1 of NAA and BA. In establishment process of explants, the most shoot length (2.07 cm per plant) was obtained on medium supplemented with 0.1 mg L-1 BA (without NAA). Maximum shoot number (5.80 per plant) was produced in medium containing 0.1 mg L-1 BA along with 0.2 mg L-1 NAA. Bud explants in culture media containing 0.2 mg L-1 NAA (without BA) and 0.1 mg L-1 NAA along with 2 mg L-1 BA produced maximum node number (3.20 per plant). The largest number of root (14.53 per plant) and root length (3.87 cm per plant) were produced on 0.2 mg L-1 NAA without BA, also 0.2 mg L-1 BA plus 0.2 mg L-1 NAA and 0.2 mg L-1 BA without NAA. Explants produced flower on medium containing 0.1 mg L-1 BA along with 0.1 mg L-1 NAA without transition of callus formation. Flower was produced from callus in medium containing 0.1 mg L-1 BA along with 2 mg L-1 NAA. Regenerated plants showed 98% survival in greenhouse during acclimatization. Acclimatized plants were morphologically similar to the mother plants.
Kwitnienie i mikropropagacja in vitro są użyteczne w programach hodowli roślin oraz produkcji komercyjnej ważnych roślin ozdobnych. Warunki in vitro, łącznie ze składnikami pożywek, rodzajem, stężeniem oraz proporcją regulatorów wzrostu roślin, a także warunkami hodowli, w sposób istotny wpływają na kwitnienie i mikropropagację in vitro. Nie istnieje żadne badanie dotyczące kwitnienia in vitro lisanthiusa (Eustoma grandiflorum). W niniejszym badaniu opracowano kwitnienie i wysoką częstotliwość mikropropagacji in vitro dla E. grandiflorum, który jest rośliną ozdobną. Mikropropagacja jest skutecznym narzędziem rozmnażania roślin ozdobnych na dużą skalę. Celem niniejszego badania była ocena wpływu różnych stężeĔ NAA i BA na mikropropagację i kwitnienie lisianthiusa in vitro. Używana pożywka hodowlana została wzbogacona za pomocą 0; 0,1; 0,2 i 2 mg L-1 NAA i BA. Przy powstawaniu eksplantów największa długość łodygi (2,07 cm na roślinę) była uzyskana na pożywce uzupełnionej o 0,1 mg L-1 BA (bez NAA). Maksymalna liczba łodyg (5,80 na roślinę) została wytworzona na pożywce zawierającej 0,1 mg L-1 BA wraz z 0,2 mg L-1 NAA. Eksplanty pączków na pożywce hodowlanej zawierającej 0,2 mg L-1 NAA (bez BA) oraz 0,1 mg L-1 NAA wraz z 2 mg L-1 BA wytworzyły maksymalną liczbę węzłów (3,20 na roślinę). Największą liczbę korzeni (14,53 na roślinę) oraz największą długość korzenia (3,87 na roślinę) zaobserwowano na 0,2 mg L-1 NAA bez BA jak również 0,2 mg L-1 BA plus 0,2 mg L-1 NAA oraz 0,2 mg L-1 BA bez NAA. Eksplanty tworzyły kwiat na pożywce zawierającej 0,1 mg L-1 BA wraz z 0,1 mg L-1 NAA bez przeniesienia kalusa. Kwiat był tworzony z kalusa na pożywce zawierającej 0,1 mg L-1 BA wraz z 2 mg L-1 NAA. Zregenerowane rośliny wykazały 98% przeżycie w szklarni podczas aklimatyzacji. Zaaklimatyzowane rośliny były morfologicznie podobne to swych roślin macierzystych.

Opis:
The experiments were carried out on Lotus corniculatus (L.) seedling root explants of the cultivar varieties Skrzeszowicka, Caroll A10 and strain 175. Callus formation and shoot regeneration were the major explant response depended mainly on of the studied genotype and used plant growth regulators (PGRs). Primary cortex of proximal and distal end of explant was the most active tissue for callus proliferation. For shoot primordia differentiation deeper zones of cortex took a part. The process of meristematic centre initiation was not uniform and various level of shoot differentiation events were observed not earlier than 3 weeks of culture. Usually, the shoot primordia regeneration began on proximal rather than distal end of the explant. BAP rather than urea derivatives stimulated shoot proliferation in extended cultures. Increasing of BAP and TDZ concentrations brought about the explant polarity and expansion of the meristematic zones. The explant position in root did not have significant influence on the number of regenerated shoots. The cultures only had better bud formation by TDZ when compared to BAP. BAP stimulated bud formation and development of the shoots from them. Short term of TDZ treatment of explants stimulated meristem formation which developed into buds and shoots. CPPU stimulated callus proliferation and bud formation when explants pretreatment was prolonged from 12 to 36 hrs.

Opis:
Helianthus tuberosus is economically important species. To improve characters of this energetic plant via genetic modification, production of callus tissue and plant regeneration are the first steps. A new, potentially energetic cultivar Albik was used in this study to test callus induction and regeneration. Callus was produced on leaves, petioles, apical meristems and stems from field-harvested plants but was totally non-morphogenic. Its induction started in the cortex and vascular bundles as confirmed by histological analysis. The surface of heterogeneous callus was partially covered with a membranous extracellular matrix surface network visible in scanning and transmission electron microscopies. The results clearly indicate that: (i) the morphogenic capacity of callus in topinambur is genotype dependent, (ii) cv. Albik of H. tuberosus proved recalcitrant in in vitro regeneration, and (iii) extracellular matrix surface network is not a morphogenic marker in this cultivar.

Opis:
Tolerance to a new herbicide, pyributycarb, was evaluated both at the plant and cellular levels. Several highly or moderately tolerant strains chosen at the plant level, showed a parallel relation of to tolerance at the cellular level. However, on the whole, correlation between total tolerance indices and survival rates of calli was not significant in 18 out of the 80 studied strains. As a result of somaclonal selection for two herbicides, lines NB-200 and NM-100 were regenerated from the tolerant calli screened with benthiocarb at 200 ppm, and molinate at 100 ppm, respectively. In the R₂ generation, both the lines displaned a stable tolerance both at the plant and cellular levels. Thus the highly tolerant mutant lines were developed from a moderately tolerant line, N-61, via in vitro selection. To achieve a short-cut method in the interspecific genetic exchange, a series of techniques related to cell fusion were established in rice and related species. Two kinds of somatic hybrids between the cultivar Kitaake and tetraploid Oryza species, O. punctata and O. officinalis, were successfully produced. Among the somatic hybrid plants, a wide range of chromosomal variation was observed. Aneuploid plants with a chromosome number around 2n = 72 (hexaploid), which are expected from a symmetric fusion between diploid and tetraploid strains, were obtained showing mixoploidy within a plant. Most of the somatic hybrids were characterized by intermediate features of plant-type showing high sterility, shattering of spikelets and reduced plant height. As an exception, a diploid plant, which was identified by RFLP analysis using the rDNA gene probe, closely resembled Kitaake and produced viable seeds. A tetraploid hybrid plant was also promising for the introduction of economically important characters through the reduction of chromosome numbers by doubled haploids. Gametoclonal variation and gamma radiation was applied to Kitaake. The mutation frequency was prominently increased by gamma ray treatment, especially at high doses of 200 Gy or 300 Gy. In the M₃R₂ or M₄R₃ generations, most of the variants showed unfavourable characters. Most of the mutant characters were governed by single or double recessive genes. Several mutants such as short culm and early flowering time might be used for rice breeding.

Opis:
Plants were regenerated from immature embryo cultures of 35 winter wheat genotypes. General responses of regenerated plants were investigated and a total of 7142 R₂ spike lines from 1593 R₁ plants were assessed in the field for somaclonal variants in 1985/86, 1986/87 and 1987/88. Selected variants were studied for their possible genetic inheritance. From regenerated plantlets, 81% survived and 63% produced fertile plants. Forms with reduced plant height, length of spike and other morphological abnormalities were found in this progeny. Populations of R₁ plants were highly variable due mainly to the physiological disturbances resulting from the in vitro process. Overall somaclonal variation frequencies were 14.2% per plant basis and 5.3% per R₂ spike basis. The variants were similar in the three different R₂ generations with predominant variants being negative in plant height, maturity, awns, spike type and plant type. Both uniform R₂ variant families and spike lines were found in addition to the segregating variants which constituted the majority. On average, in a variant family or line, 18% and 14% of their component lines and plants were variants, respectively. Inheritability was demonstrated for the uniform variant families and spike lines as well as segregated variants. Of those 134 selections, about 70% were classified as inheritable. Both recessive and dominant gene mutations at one, two or three loci were evident in some variants as suggested by the segregating data.
