Opis:
Many chrysanthemum mutants are chimeras built from tissues of a varied genetic composition. Regeneration in vitro of somatic embryos from the whole mutated ligulate florets or only from their small mutated fragments can lead to the separation of chimera components and, as a result, producing a new original cultivar. There was determined the effect of growth regulators (2,4-D; KIN or BAP) and explant type (whole or transversely-cut-into-half ligulate florets) on the efficiency of somatic embryogenesis of Chrysanthemum × grandiflorum (Ramat.) Kitam. ‘Cool Time’. For the induction of the somatic embryogenesis ant the regeneration of somatic embryos the MS medium [Murashige and Skoog 1962] with 18.08 μM 2,4-D as well as with this auxin and 4.44; 8.88; 22.20 μM BAP or 4.65; 9.30; 23.25 μM KIN was used. The best results were obtained when transversely-cut-into-half ligulate florets were inoculated onto the medium with 4.65 μM KIN and 18.08 μM 2,4-D. This results may increase the probability of success in separation of chimera components in chrysanthemum breeding.
Wiele mutantów chryzantem jest chimerami zbudowanymi z tkanek o różnym składzie genetycznym. Regeneracja in vitro zarodków somatycznych z całych objętych mutacją kwiatów języczkowatych lub tylko z ich niewielkich zmutowanych fragmentów może doprowadzić do separacji komponentów składowych chimery i w rezultacie do uzyskania nowej, oryginalnej odmiany. W badaniach określono wpływ regulatorów wzrostu (2,4-D; KIN lub BAP) oraz rodzaju eksplantatu (cały lub przecięty poprzecznie na pół kwiat języczkowaty) na wydajność embriogenezy somatycznej u Chrysanthemum × grandiflorum (Ramat.) Kitam. ‘Cool Time’. Do indukcji embriogenezy somatycznej oraz do regeneracji zarodków somatycznych zastosowano pożywkę MS [Murashige and Skoog 1962] uzupełnioną jedynie 18,08 μM 2,4-D, a także tą auksyną oraz 4,44; 8,88; 22,20 μM BAP lub 4,65; 9,30; 23,25 μM KIN. Najlepsze rezultaty uzyskano, inokulując przecięte poprzecznie na pół kwiaty języczkowate na pożywkę z 4,65 μM KIN i 18,08 μM 2,4-D. Uzyskane wyniki mogą przyczynić się do zwiększenia prawdopodobieństwa separacji komponentów chimer w hodowli chryzantem.

Opis:
The potential of immature zygotic embryos to produce embryogenic tissue was tested using culture media differed in inorganic salt composition as well as plant growth regulator content. Explants cultured on DCR as well as MLV media gave the highest initiation percentages with maximum values of 8.8% (MLV) to 10.4% (DCR). Plant growth regulators content (standard or reduced) had no profound effect on embryogenic tissue initiation. Somatic embryo maturation as well as germination was dependent on the cell line and salt composition of the medium. Plantlet regeneration occurred in three cell lines out of five tested. During the maturation process profound changes occurred in the internal organisation of somatic embryos such differentiation of root meristem in precotyledonary somatic embryos and formation of provascular strands in cotyledonary somatic embryos.

Opis:
Somatic embryogenesis was studied in four spruce species (Picea abies, P. omorika, P. pungens 'Glauca' and P. brewenana) to determine if this method can be used for in vitro propagation of coniferous trees. The highest frequency of initiation of embryogenic tissue was obtained when mature zygotic embryos were used as explants. It ranged then from 10.8% (P. brewenana) to 23.75% (P. omorika and P. pungens 'Glauca'). The frequency of embryogenic tissue initiation was strongly affected by medium composition, i.e. addition of appropriate auxins (2,4-D, NAA, Picloram) and sucrose concentration (10-20 g-1"1). A lower frequency was obtained in Picea omorika (10%) when megagametophytes (endosperms with immature zygotic embryos) were used as explants. No emryogenic tissue was produced from hypocotyls, cotyledons and needles. A satisfactory frequency was achieved with the use of somatic embryos of Picea abies (30%). The proliferation of embryogenic cell lines of spruces was affected by medium type. The experiments resulted in production of somatic plantlets of P. abies and P. omorika. This enables the application of this method of spruce micropropagation for genetic and breeding research or for nursery production.

Opis:
The studies were carried out on seed explants (mature zygotic embryos) of four spruce species: Picea omorika (Pancić) Purk., P. pungens ‘Glauca' Beisnn., P. breweriana S. Watson and P. abies (L.) Karst. The explants required darkness during the induction of embryogenic tissue. Temporary exposure of explants to light did not increase their embryogenic capacity. It was observed that the temperature of 25°C was the optimal for embryogenic tissue induction from mature zygotic embryos of Picea omorika. Cold treatment at 4°C during one week improved embryogenic tissue initiation in the explants of P. pungens ‘Glauca'. Seed explants of Picea omorika produced embryogenic tissue on medium lacking glutamine. Only explants of Picea abies and P. omorika showed embryogenic tissue formation. For effective proliferation of embryogenic tissue in Picea abies and P. omorika it was necessary to supply the medium with 2,4-D (4.5-9 μM) and BA (2.25 μM). Two of three analized lines showed that ABA promote somatic embryo maturation, at the ABA concentration 20 μM in the medium.

Opis:
Anthers of twenty triticale genotypes were cultured on three different media: 1 - PII (Chuang et al. 1978) with increased 2,4-D to 2 mg L⁻¹ and agarose 6 g L⁻¹ , 2 - Macro-, micronutrients and vitamines like in MN6 (Chu, Hill 1988) + 2 mg L⁻¹ 2.4-D + 0.5 mg L⁻¹ KIN + 5 mg L⁻¹ FeEDTA + 90 g L⁻¹ sucrose; 3 - Macro-, micronutrients and vitamines like in MN6 (Chu, Hill, 1988) + 2 mg L⁻¹ 2.4-D + 0.5 mg L⁻¹ KIN + 5 mg L⁻¹ FeEDTA + 120 g L⁻¹ sucrose. Embryoid induction and plant regeneration were influenced by donor plant genotype and induction medium. Medium 1 was the best for embryoid induction, while for green plant regeneration the best were media 1 and 2. Out of 300 anthers from each genotype plated on each of the three media, 64-1250, 12-486 and 6-212 somatic embryos and 8-86, 3-136 and 1-26 green plants were recorded, on media 1, 2 and 3, respectively.

Opis:
Two-dimensional gel electrophoresis was used to compare protein expression profiles between various stages of Gentiana kurroo Royle somatic embryos. Seven distinct stages (I–VII) were pointed out and measured from long-term embryogenic cell suspension. Isoelectric focusing was done in the pH intervals 3–10, and the second dimension was carried out with 13% SDS-polyacrylamide gel electrophoresis. Dependent on the stage from about 400 (stage IV) to more than 700 (stage II) protein spots were totally detected. The molecular weight of abundant proteins range from 12 to 70 kDa, however, majority of proteins were located between 20–49 kDa spots on the gels. The highest difference in the number of spots appeared in the case of globular embryo (stage I) and elongated cotyledonary stage (stage VII) with differences being about 130 spots. The relevance of embryogenic cell suspension choice for proteomic analysis as well as expediency of the increasing number of particular embryo stages is discussed.

Opis:
Microscopic analysis of embryogenic tissues of Picea abies and P. omorika showed that the tissues differed in proportions of various types of proembryogenic masses, and in presence/absence of early somatic embryos, which suggests that they differed in embryogenic potential. On the basis of this study, embryogenic competence of tissues can be assessed at early stages of somatic embryogenesis, and thus the most efficient lines can be selected (one Picea abies and two P. omorika). In the course of development of somatic embryos embryogenic tissue was placed on a medium with abscisic acid (ABA), which affects an increase in osmotic pressure at the stage of maturation of somatic embryos and finally on the regeneration of cotyledonary embryos. In this stage of embryos development, storage materials were accumulated, which are used in specific metabolic processes during embryo development.

Opis:
The effect of cold pretreatment of spikes on somatic embryo induction and anther culture response of 25 F₁ winter wheat hybrids was investigated. The efficiency of androgenic embryos was the highest when spikes were incubated at 4°C for 6-9 days. A total of 2242 (73.0%) green and 885 (27.0%) albino plants were obtained from 9900 cultured anthers. Anther culture response in wheat was found to be markedly affected by the genotype of donor plants. The percentage of green plants varied from 0 to 115.7%. A great majority of anther-derived regenerants were haploids (82.35%), while the remaining plants were spontanoeus diploids (13.73%) and aneuploids (3.92%).
