Genetic diversity and mycelial compatibility groups of the plant-pathogenic fungus Sclerotinia sclerotiorum in Brazil.
The genetic variability of 40 Sclerotinia sclerotiorum isolates from various fields widely distributed throughout Brazil and different host crops was analyzed using RAPD markers and mycelial compatibility groupings (MCGs). The isolates were characterized using 16 random primers of the OPERON series, which produced 121 DNA fragments. UPGMA cluster analysis using Jaccard's genetic distance and MC...
متن کاملAssessment of genetic diversity among sunflower genotypes using microsatellite markers
Genetic diversity estimation of plant materials is one of the important pre-breeding activities in breeding field crops. Twenty-one microsatellite markers used to assess genetic diversity and relationship of 68 sunflower genotypes (Helianthus annuus L.). All of 21 pairs of SSR (Simple Sequence Repeats) markers produced a total number of 49 polymorphic bands. DNA fragments ranged from 9...
متن کاملMycelial Compatibility Grouping and Aggressiveness of Sclerotinia sclerotiorum
A pernicious pathogen, Sclerotinia sclerotiorum (Lib.) de Bary has a wide geographic distribution and a diverse host range, including many agronomic crops (16). On soybean, S. sclerotiorum causes Sclerotinia stem rot (SSR), a disease recognized as an important yield-reducing disease in the United States (41) and a major disease on soybean in Illinois (15). Partial resistance associated with eit...
متن کاملAn optimized method for mycelial compatibility testing in Sclerotinia sclerotiorum.
Classification of isolates into mycelial compatibility groups (MCGs) is used routinely in many laboratories as a quick marker for genotyping Sclerotinia sclerotiorum within populations. Scoring each new sample requires optimization of standardized conditions to support adequate growth of all paired isolates. Appropriate conditions for growth are especially important because diverse compatibilit...
متن کاملmycelial compatibility groupings and pathogenic diversity of sclerotinia sclerotiorum (lib.) de bary populations on canola in golestan province of iran
genetic structure and pathogenic diversity of sclerotinia sclerotiorum, the causal agent of canola white stem rot, were assessed through mycalial compatibility groupings (mcgs), a comparison and comparing of isolate virulence. fifty-seven isolates from three different regions in golestan province were selected for mycelial compatibility and as well for virulence tests. within the 57 tested isol...
