Pythium is a fungus-like genus with worldwide distribution that is found in most terrestrial and aquatic ecosystems. It is a species-rich genus contains important plant pathogenic species. Little is known on the systematics of Pythium in West Azarbaijan province (N.W. Iran). Thus, the aim of this study was to identify 200 isolates collected from different cultivated soils of West Azarbaijan pro...

Late blight, a disease caused by oomycota, Phytophthora infestans, is greater threat to the potato crop than any other in Mauritius. This remains most challenging manage once symptoms have appeared, thus requiring rapid detection for effective management. The aim of this study was compare different methods early causal agent late blight. Conventional culture-based involved direct isolation P. i...

• We analysed air dispersal of Cercozoa and Oomycota with an sampler in tree crowns. Oomycete community assembly is driven by random factors neutral processes. Distribution protistan propagules through the was not spatially restricted. Our results demonstrate pathogens from outside biome. Air may explain ubiquitous presence forests. contain a huge biodiversity important forest trees other veget...

Abstract Investigations into simple holocarpic oomycetes are challenging, because of the obligate biotrophic nature many lineages and periodic presence in their hosts. Thus, despite recent efforts, still, majority species described remains to be investigated for phylogenetic relationships. One these is Aphanomycopsis bacillariacearum , type genus . Species endobiotic parasites diverse hosts (e....
