Variation in competitive ability among isolates of Aspergillus flavus from different vegetative compatibility groups during maize infection.

ABSTRACT Aspergillus flavus, the primary causal agent of aflatoxin contamination, includes many genetically diverse vegetative compatibility groups (VCGs). Competitive ability during infection of living maize kernels was quantified for isolates from 38 VCGs. Kernels were inoculated with both a common VCG, CG136, and another VCG; after 7 days (31 degrees C), conidia were washed from kernels, and...

Analysis of Soil Populations of Aspergillus flavus Link. from Pistachio Orchards in Iran for Vegetative Compatibility

One hundred-thirty soil isolates of A. flavus were collected from commercial pistachio orchards in two main production regions including Rafsanjan (Kerman Province, south-eastern of Iran) and Damghan (Semnan Province, central north of Iran) and assayed for vegetative compatibility groups (VCGs). The sixteen and twenty VCGs were identified for 41 and 37 nit-mutant producing isolates of A. flavus...

Genetic isolation among sympatric vegetative compatibility groups of the aflatoxin-producing fungus Aspergillus flavus.

Aspergillus flavus, a fungal pathogen of animals and both wild and economically important plants, is most recognized for producing aflatoxin, a cancer-causing secondary metabolite that contaminates food and animal feed globally. Aspergillus flavus has two self/nonself recognition systems, a sexual compatibility system and a vegetative incompatibility system, and both play a role in directing ge...

DNA Fingerprinting Analysis of Vegetative Compatibility Groups in Aspergillus flavus from a Peanut Field in Georgia

Aspergillus flavus Link:Fr. may infect seed of corn, cotton, peanut, and tree nuts and contaminate them with aflatoxins, which are potent hepatoxic, carcinogenic metabolites that pose a significant health hazard (3,4). Members of Aspergillus section Flavi are widespread in crop fields, particularly in subtropical to tropical latitudes (5,11,17,19). Population biologists seek to understand the g...

Vegetative compatibility and rep-PCR DNA fingerprinting groups of Fusarium solani isolates obtained from different hosts and their pathogenicity

Fusarium solain is the most important pathogen of huge range of plant hosts, especially potato in the word, which causes tuber rot in storage and root rot of potato plants in fields. Fifty four isolates from potato, bean, chickpea and cucurbit (melon, watermelon and cucumber) was subjected in a study through analysis of vegetative compatibility groups (VCGs) and rep-PCR DNA fingerprinting. Nit ...
