Variability in morphology and aggressiveness among North American vegetative compatibility groups of Colletotrichum coccodes.
North American isolates of Colletotrichum coccodes, representing six vegetative compatibility groups (NA-VCG), were used to study morphological and pathogenic variability. The objective was to determine if variability in conidial and microsclerotial size was related to pathogenicity. Significant differences were detected in length, width, and length/width ratios of conidia as well as in the len...
متن کاملGenetic Variability in the Potato Pathogen Colletotrichum coccodes as Determined by Amplified Fragment Length Polymorphism and Vegetative Compatibility Group Analyses.
ABSTRACT Amplified fragment length polymorphism (AFLP) using three primer sets was used to characterize 211 Colletotrichum coccodes isolates from North America, 112 of which were assigned to six vegetative compatibility groups (VCGs) using nitrate nonutilizing (nit) mutants. These isolates clustered into five corresponding groups by unweighted pairgroup method with arithmetic means-based cluste...
متن کاملGenetic relatedness of Brazilian Colletotrichum truncatum isolates assessed by vegetative compatibility groups and RAPD analysis.
The genetic variation among nine soybean-originating isolates of Colletotrichum truncatum from different Brazilian states was studied. Nitrate non-utilizing (nit) mutants were obtained with potassium chlorate and used to characterize vegetative compatibility reactions, heterokaryosis and RAPD profile. Based on pairings of nit mutants from the different isolates, five vegetative complementation ...
متن کاملVegetative compatibility and genetic analysis of Colletotrichum lindemuthianum isolates from Brazil.
The causal agent of common bean anthracnose, Colletotrichum lindemuthianum, has considerable genetic and pathogenic variability, which makes the development of resistant cultivars difficult. We examined variability within and between Brazilian pathotypes of C. lindemuthianum through the identification of vegetative compatibility groups (VCGs) and by RAPD analysis. Two hundred and ninety-five ni...
متن کاملVegetative 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 ...
