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 کاملThe degradation of onion cell walls by extracellular enzymes of Botrytis allii and Sclerotium cepivorum [proceedings].
Botrytis allii and Sclerotium cepivorum, which respectively cause neck rot and white rot of onions, produce a range of cell-wall-degrading enzymes in onion tissue (Hancock et al., 1964; Beck, 1976). The two fungi have been grown on liquid media using purified onion cell walls, prepared by an adaptation of the method of Jarvis et al. (1977), as the sole carbon source for B. allii and the major c...
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 کاملMolecular Identification of Trichoderma spp. in Garlic and Onion Fields and In Vitro Antagonism Trials on Sclerotium cepivorum
Trichoderma species are non-pathogenic microorganisms that protect against fungal diseases and contribute to increased crop yields. However, not all Trichoderma species have the same effects on crop or a pathogen, whereby the characterization and identification of strains at the species level is the first step in the use of a microorganism. The aim of this study was the identification – at spec...
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...
