Genetic diversity of Bradyrhizobium japonicum field population revealed by RAPD fingerprinting

Genetic relatedness of Bradyrhizobium japonicum field isolates as revealed by repeated sequences and various other characteristics.

Forty-nine isolates of Bradyrhizobium japonicum indigenous to a field where soybeans were grown for 45 years without inoculation were characterized by using four DNA hybridization probes from B. japonicum. nifDK-specific hybridization clearly divided the isolates into two divergent groups. Diversity in repeated-sequence (RS)-specific hybridization was observed; 44 isolates derived from 41 nodul...

The effect of Trap Plants on the Population Diversity of Bradyrhizobium japonicum

A high genetic diversity revealed between commercial rose cultivars by RAPD-PCR technique

Genetic diversity between fifteen commercial cultivars of rose were evaluated, using Ten decamer primers (A-J). All primers detected polymorphism among the cultivars. In total, 126 bands were produced, 73 of which were polymorphic. Primers E and F produced the highest, while primer H produced the lowest number of bands. The percentage of polymorphic bands ranged from 37% to 81% with an average ...

Genetic Diversity and Population Structure of Iranian tulips revealed by EST-SSR and NBS-LRR Markers

The genus Tulipa L. (Liliaceae) comprises about 100 species and Iran is considered as one of the main origins of tulips. In this research, genetic diversity and population structure of 27 wild populations of tulips collected from Iran were studied by 15 highly polymorphic and reproducible expressed sequenced tag-simple sequence repeat (EST-SSR) markers and 8 nucleotide binding site (NBS)-enzyme...

Genetic diversity of Iranian melon cultigens revealed by AFLP markers

Iran is a part of the secondary centre of origin of melons, and therefore, there is a wealth of genetic variation of these species in this country. The Amplified Fragment Length Polymorphism (AFLP) marker was applied to investigate the genetic variations among five major Iranian melon cultigens (Cucumis melo) and ‘Ananasi’ as a general well-known cultivar. Ten primer pairs were used on 90 indiv...
