Opis:
A total of 96 indigenous Brassica rapa accessions were collected from different locations of Khyber Pakhtunkhwa, Pakistan. Simple Sequence Repeats (SSR) markers were used to identify the most diverse genotypes among the collected lots. Twenty six (26) different SSR primers were used for (genetic) variability among collected genotypes. These primers were selected from literature based on their previous results. These primers produced 135 scorable bands of which 75 were polymorphic, with an average of 55.5% polymorphic loci, and reflected the broader genetic background of the collected genotypes. An average 2.88 polymorphic bands with an average PIC value of 0.49 was recorded. Unweighted Pair Group Method with Arithmetic Mean (UPGMA) divided all genotypes into three main groups. Group one contained three clusters, while group two and three had four and two clusters each. Based on the UPGMA dendrogram, genotypes collected from Kohat, Bannu, Swat and Haripur showed considerable amount of variation. From the present study, it is concluded that SSR markers can be proved as the best tool for the genetic variability of other local and exotic B. rapa genotypes.

Opis:
Pyricularia grisea, the rice blast fungus is the main pathological threats to rice crop in Iran and worldwide. In this research was evaluated the genetic diversity of P. grisea collected from different fields of Guilan province by using of 14 microsatellite primers. These primers produced 64 polymorphic bands by an average of 4.57 bands for each marker. An average of polymorphic information content in whole primers was 0.734, an average of effective number of alleles was 2.68, an average of Nei’s expected heterozygosity was 0.734 and an average of Shannon’s information index was 1.05. Primer SSR43,44 had the most polymorphic information content (PIC = 0.85), observed number of alleles (na = 8), effective number of alleles (ne = 3.76), Nei’s expected heterozygosity (Ne = 0.861) and Shannon’s information index (I = 1.38). This marker was the best primer between 14 used primers for evaluation the genetic diversity of P. grisea. Cluster analysis was done with simple matching similarity matrix and UPGMA method. The results showed that the studied isolates were classified into 3 lineages by cutting off the dendrogram at 0.76 similar linkage level. Number 1 was the major group and represented most of those isolates. Results of principal coordinate analysis also divided the isolates into three groups exactly similar to obtained with cluster analysis. Overall, our results confirmed that microsatellite primers were good and suitable markers for analyzing structure of P. grisea
Pyricularia grisea, grzyb zarazy ryżowej, jest zagrożeniem dla plonów ryżu w Iranie i na całym świecie. W niniejszym badaniu przy użyciu 14 markerów mikrosateklitarnych oceniano różnorodność genetyczną P. grisea zebranego z różnych pól prowincji Guilan. Markery te tworzyły 64 polimorficznych wiązać przy średnio 4,57 wiązaniach dla każdego markera. ĝrednia informacji polimorficznych we wszystkich markerach wynosiła 0,734, średnia efektywna liczba alleli – 2,68, średnia heterozygotyczność oczekiwana Nei – 0,734 a średni indeks informacji Shannon – 1,05. Marker SSR43,44 miał największą zawartość informacji polimorficznej (PIC = 0.85), największą liczbę alleli obserwowanych (na = 8), liczbę efektywnych alleli (ne = 3.76), największą heterozygotyczność oczekiwaną Nei (Ne = 0,861) i indeks informacji Shannon (I = 1.38). Był to najlepszy spośród 14 markerów użytych do oceny różnorodności genetycznej P. grisea. Analizę skupieć przeprowadzono za pomocą prostego współczynnika simple maching oraz metody UPGMA. Na podstawie wyników badać izolaty zaklasyfikowano do 3 linii przez odcięcie dendogramu na podobnym poziomie powiązać 0,76. Numer 1 był główną grupą i reprezentował większość tych izolatów. Wyniki analizy głównych współrzędnych także dzieliły izolaty na trzy grupy podobne do tych, które otrzymano za pomocą analizy skupieć. Podsumowując, wyniki badać potwierdziły, że markert mikrosatelitarne to dobre i odpowiednie markery do analizy struktury P. grisea.

Opis:
Arnica montana L. is one of the most important herbal plants used in medicine, pharmaceutical and cosmetic industry. The number of studies performed with molecular markers on arnica genotypes is very limited. Because of this fact the aims of presented examination were optimization of protocols DNA isolation from fresh leaves of A. montana and identification of genetic diversity among this plant genotypes. In presented study to obtain pure DNA Plant & Fungi DNA Purification Kit (EURx) were used. To clean obtained DNA long and slow electrophoresis and isolation DNA from gels were used. A. montana genotypes were analyzed using 40 RAPD primers (Operon Technologies), out of which 12 produced high number of polymorphic and repeatable fragments. In total, selected primers produced 120 fragments, among them 111 (92.5%) were polymorphic. The genetic similarity matrices were produced based on RAPD using the Dice’s coefficient. RAPD based genetic similarity was estimated between 0.535 and 0.945. The highest genetic similarity was estimated among GA17 and GA18 genotypes, which are closely located on the obtained dendrogramme.
Arnica montana L. jest jedną z najcenniejszych roślin zielarskich wykorzystywanych w medycynie, farmacji i przemyśle kosmetycznym. W dostępnej literaturze liczba doniesień związanych z analizą molekularną arniki jest znikoma, dlatego też celem prezentowanych badań była optymalizacja procesu izolacji DNA ze świeżych liści oraz identyfikacja zróżnicowania genetycznego oparta na markerach RAPD. W prezentowanej pracy w celu uzyskania czystego DNA do izolacji wykorzystano zestaw DNA Plant & Fungi DNA Purification Kit (Euro) oraz oczyszczanie za pomocą długiej elektroforezy w żelu agarozowym. Spośród testowanych 40 starterów RPAD do analiz wybrano 12 generujących stabilne i polimorficzne wzory prążków. Wyselekcjonowane startery amplifikowały 120 fragmentów, spośród których 111 (92,5%) było polimorficznych. Wykorzystujac markery RAPD utworzono matryce podobieństwa genetycznego. średnia wartość podobieństwa analizowanych genotypów wynosiła 0.886. Najwyższy współczynnik podobieństwa genetycznego oszacowano pomiędzy genotypami GA17 i GA18, które ulokowały się blisko siebie na uzyskanym dendrogramie.

Opis:
An extremely endangered population of Viola uliginosa Besser at the classical locality of this taxon has been studied. The AFLP analysis was based on 18 specimens of V. uliginosa (about 10% of preserved individuals); additionally, two individuals of V. riviniana were included in the data set as the out group. A high genetical uniformity of the whole population (similarity indexes close to 1) was detected. It was not correlated significantly with the spatial distribution of the plants. The study serves as a basis for practical conservation measures and at the same time as a starting point for a more extensive research on the genetical variability of the species throughout its range.

Opis:
Coccinia abyssinica (Lam.) Cogn. (local name anchote) is a tuber crop that belongs to the family Cucurbitaceae and it is cultivated for food and medicinal uses. It has relatively high quality of nutrient composition compared to other tuber crops, and is considered as the leading proteinous root crop with a high calcium content. Therefore, cooked anchote tubers are highly recommended for patients with broken or fractured bones. Anchote also contains alkaloids, phenols, tannins, flavonoids, and saponins. Although anchote is principally cultivated for its tubers, farmers prefer propagation by seeds as they are easy to store. Farmers select high-quality fruits for future seeds, based on the size of fruits and tubers. Since diseases and pests rarely affect the tubers, protection is not common. However, the fruit fly can damage the fruits, which predisposes them to decay. Although anchote has very high potential as a food security crop, it is neglected and underutilized and has received very limited research attention. Research published so far covers its ethnobotany, nutritional and anti-nutritional composition, traditional methods of reproduction, in vitro reproduction, somatic embryogenesis, anther breeding, and morphological and molecular genetic diversity. This article includes an analysis of previous and current research achievements, presents findings in a comprehensive way, and suggests future direction in crop improvement using biotechnological tools.

Opis:
We have investigated genetic diversity and the mating system of Scots pine plus trees from the Tuchola Forests – Poland, using allozymes as genetic markers. The studied plus trees possess high genetic diversity (expected heterozygosity He = 0.427) and low inbreeding (Wright’s index F = –0.028), which is comparable to Scots pine trees observed in other studies in natural populations and seed orchards. The mating system analyses revealed that almost all offspring produced by the plus trees were due to outcrossing (tm = 0.983), with no apparent bi-parental inbreeding. The estimate of correlation of paternity indicated that each of mother trees is pollinated on average by a relatively large number of effective males (Nep = 30.3). The observed genetic diversity and mating system patterns indicate that the seeds produced by the studied plus trees possess high genetic variation needed in reforestation processes.

Opis:
The study shows genetic diversity of 38 Vitis vinifera L. cultivars and hybrids originating in North America and Europe, including cultivars selected in Poland, which have not been characterized with the use of DNA markers yet. The agrobiological features of the genotypes selected for testing indicate that they may be useful for the breeding of new cultivars and grape production. The use of 12 ISSR primers allowed to obtain 94.4% of polymorphism. The polymorphic information content (PIC) value was high and varied between 0.829 and 0.953 with an average of 0.897. The resolving power (Rp) ranged between 3.678 and 8.892 with an average of 6.347. Primers UBC 809, UBC 810, UBC 812, UBC 855, UBC 891 and UBC 810 were found to be highly effective (informative). Similarity coefficient ranged between 0.167 and 1.0, which indicates high degree of diversity of tested grape cultivars. Tested cultivars were grouped in 3 main clusters; one of them was further divided into 6 subclusters. ‘Pannonia Kincse’ and ‘Danmarpa Polonia’ were not differentiated. Phenotypic differences among those two cultivars suggest that ‘Danmarpa Polonia’ might be a clone of ‘Pannonia Kincse’ and other molecular techniques must be used to differentiate them. Morphological and agrobiological characters of cultivars support the results obtained by ISSR markers.

Chamaedaphne calyculata is rare and endangerded species of Polish flora. The genetic variation within and among ten polish population of leatherleaf was analysed by ISSR and ISJ markers. The analysis revealed a total of 160loci with an average of 13.3 bands per primer. We expected a low level of genetic diversity of this narrowly distributed species in Poland, but our results indicate that Ch. calyculata revealed a high level of genetic diversity at species level (P=88.7%of polymorphic loci, AE=1.468, HE=0.290). At the population level, the variation of Ch. calyculata was significantly lower (P=27.6%, AE=1.140, HE=0.098). There was significant correlation between ecological properties (population size; number of flowering ramets) and genetic diversity parameters. Analysis of molecular variance showed that most of variation (62%) in Ch. calyculata occurred among population. Gene flow (Nm) between the ten studied populations, determined based on the GST index, was very low at 0.239. It indicated that the fragmentation and isolation of populations might result from specific evolutionary history of this plant and postglacial recolonization

Opis:
Genetic diversity of Galium cracoviense, a narrow endemic species, limited to the small area in southern Poland and concentrated on Jurassic limestone outcrops near Częstochowa, was examined using the AFLP marker. Twenty nine individuals from three spatially isolated populations were used for the study. AFLP analysis yielded 157 bands, of which 110 (70%) were polymorphic. The AMOVA analysis revealed a substantially higher variation within populations (89.35%) than among them (10.65%). Values of parameters describing population genetic diversity, such as Shannon index and gene diversity index estimated for each population, were highly similar. The results indicate a high level of genetic polymorphism as well as a high genetic similarity of the isolated populations of G. cracoviense and thus an unconstrained gene flow between them. Based on the results we conclude that additional demographic and genetic studies, are necessary to monitor potential decrease of populations size resulting mainly from the mechanical destruction of plants and their habitats caused by intense tourism. Due to the small general range of occurrence, conservation should include the highest possible number of populations of G. cracoviense.

Opis:
Fragmented distribution, the breeding system and effects of genetic drift in small-size populations occurring at edge of the species range play an important role in shaping genetic diversity of such a species. Melica transsilvanica is a plant rare in the flora of Poland, where it reaches the northern limit of its continuous range. Amplified Fragment Length Polymorphism (AFLP) DNA profiling method was applied to measure genetic diversity among and within populations of M. transsilvanica. Additionally, genetic relationships between M. transsilvanica and Melica ciliata, two closely related species, were explored. A total of 68 plants from 7 populations of M. transsilvanica and 24 plants from 2 populations of M. ciliata, collected in Poland and outside it, were analyzed. Using 294 AFLP fragments from 3 primer combinations, accessions were grouped into two major clusters associating with M. ciliata and M. transsilvanica, respectively. Further, two subclusters, corresponding to the samples collected from the Pieniny Mts and from the Kraków - Częstochowa Upland were clearly distinguished within the M. transsilvanica group. The hierarchical AMOVA exhibited significant genetic distinction between these geographic regions (60.89%, p < 0.001). The obtained results showed that the most genetic diversity resided between the populations of M. transsilvanica (86.03%) while considerably lower genetic variation was found within the populations (13.97%), which is consistent with the results reported for self-plants. The low level of AFLP genetic variation of M. transsilvanica can be caused by the geographic isolation of populations, which preserves the dominant self-mating breeding system of the species. Individual populations of M. transsilvanica are characterized by isolated gene pools differing by a small number of loci.

Opis:
The wild-harvested fruit of Vaccinium oxycoccos (European cranberry) is used medicinally in many European and North American countries; the plant, however, is seldom cultivated. In order to optimize the collection strategy and improve the horticulturally important characters of V. oxycoccos clones, comprehensive investigations of the species are necessary. In the present study we investigated the phenological, morphological and genetic diversity of 29 clones originating from two wild populations growing in two strictly protected Lithuanian reserves, Čepkeliai and Žuvintas. During an ex situ collection at Kaunas Botanical Garden, we observed great phenological variation between the collected V. oxycoccos clones. The following morphological traits most clearly distinguished our study clones: leaf size, berry shape, berry size and fruit colour at full maturity. The genetic variation of V. oxycoccos clones from the two populations was assessed using RAPD and SSR. RAPD analysis conducted with 9 primers resulted in 146 polymorphic loci for the total sample, and SSR analysis with 5 primers revealed 29 alleles for the total sample. A greater degree of polymorphism was demonstrated for the Čepkeliai population than for the Žuvintas population. The study allowed the selection of several clones having promising morphological traits for further testing in the field.
