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...

Verticillium dahliae was isolated from Noogoora burr (Xanthium occidentale) seeds collected mature asymptomatic plants in 2017 growing along the riverbank at Condobolin, NSW. V. by transferring surfaced-disinfested seed components onto 25% Potato Dextrose Agar (PDA) plus Novobiocin. Morphological and molecular analysis, as well fulfilment of Koch’s postulates, confirmed causal pathogen dahliae....

Mycoviruses are the viruses that infect fungi and prevalent in all major groups of plant pathogenic and edible fungi. The first mycovirus was reported in 1962 from the cultivated mushroom (Agaricus bisporus); the infected mushrooms developed malformed fruiting bodies, grow slowly, mature early and resulting in serious yield losses. Although the majority of known mycoviruses have dsRNA genomes t...

Vegetative compatibility groups (VCGs) are determined for many fungi to test for the ability of fungal isolates to undergo heterokaryon formation. In several fungal plant pathogens, isolates belonging to a VCG have been shown to share significantly higher genetic similarity than those of different VCGs. In this study we sought to examine the relationship between VCG and genetic similarity of an...
