| Popis: | The genetic structure among Iranian populations of Fusarium verticillioides from the main corn growing areas of five provinces including Ardabil, Fars, Mazandaran, Khorasan, and Khuzestan were evaluated using VCG, RAPD and rep-PCR. Sixty-one isolates of F. verticillioides were placed in 14 Vegetative Compatibility Groups and 19 haplotypes. VCG3 with 14 members (23% of all isolates) was the most frequent VCG. RAPD-PCR and rep-PCR generated multiple distinct products demonstrated considerable variability among the isolates of different VCGs. Haplotype 1(HP1) had the highest frequency (0.57) in the population and was present in isolates from the majority of the locations in this study. All molecular phenotypes were distributed randomly across the various locations. Although there are some consistent between geographical origin of the isolates and their genetic similarity but VCG groups were distributed among different geographical locations and there was no correlation between geographical distribution and VCG groups. Gene diversity was 0.2909 and populations of F. verticillioides were placed in five distinct groups based on geographical origin. The highest genetic distance observed between Fars and Khuzestan (0.1801) and the smallest genetic distance was obtained between Ardabil and Khuzestan (0.0589). Analysis of molecular variance (AMOVA) showed a significant difference among populations of F. verticillioides. According to our results PhiPT was equal to 0.176 (p |
