چکیده

the genetic diversity of 20 iranian populations of bunium persicum has been evaluated with random amplified polymorphic dna (rapd) and amplified fragment length polymorphism (aflp) markers. fresh leaves of seedlings from each population were used for genomic dna extraction. analysis of banding patterns of 15 rapd primers and 17 aflp primer combinations, revealed 192 (86%) and 228 (75%) polymorphic bands, respectively. the range of similarity coefficients within populations were 0.4-0.82 for rapd and 0.39-0.96 for aflp markers. no association was observed between similarity matrices of both the dna markers. genetic distance patterns between b. persicum populations, expressed by the rapd and aflp cluster analyses were relatively different. the resulting dendrograms based on aflp and rapd + aflp markers were more similar when compared to that derived from rapd analysis. the aflp generated dendrogram was supported with the highest bootstrap values. the measures of relative genetic distances among populations did not completely correlate with geographical distances of places of their origin. several populations of black cummin were represented as independent groups in the clusters, showing a high level of genetic diversity and unique genetic background. knowledge of wide genetic diversity observed in the b. persicum populations provides important information for management of germplasm resources with regard to future domestication and breeding programs.

Evaluation of Genetic Diversity in Iranian Violet (Viola spp) Populations Using Morphological and RAPD Molecular Markers

Recognition of genetic reserves and desirable genes is the basis of breeding programs. So far, in Iran, due to the lack of recognition of genetic resources, a considerable breeding program has not been done on native plants. The study of the genetic diversity of violets as a native plant with ornamental and medicinal uses is the great importance in advancing the breeding goals of this plant. So...

Genetic diversity in natural populations of Jacaranda decurrens Cham. determined using RAPD and AFLP markers

Jacaranda decurrens (Bignoniaceae) is an endemic species of the Cerrado with validated antitumoral activity. The genetic diversity of six populations of J. decurrens located in the State of São Paulo was determined in this study by using molecular markers for randomly amplified polymorphic DNA (RAPD) and amplified fragment length polymorphism (AFLP). Following optimization of the amplification ...

Comparison of ISSR and AFLP markers in assessing genetic diversity among Nettle (Urtica dioica L.) populations.

Urtica dioica is an important medicinal plant which is widely distributed in Mazandaran province (North of Iran). In this study for the first time Amplified Fragment Length Polymorphism (AFLP) and Inter-simple Sequence Repeat (ISSR) markers were used for detection of genetic polymorphism in Mazandaran nettle. Ten AFLP primer combinations and seventeen ISSR markers were utilized. AFLP produced 830...

Genetic diversity of Neotyphodium fungal endophytes in three Iranian grass species using AFLP molecular markers

Genetic diversity of fungal endophytes, Neotyphodium species, was studied in grasses Festuca arundinacea, F. pratensis and Lolium perenne using AFLP  markers. Fungi were isolated from the host leaf sheaths and Neotyphodium species were selected based on morphological characteristics. To confirm identity of selected fungi belonging to the genus Neotyphodium, polymerase chain reaction was perform...
