Saprotrophic Arachnopeziza Species as New Resources to Study the Obligate Biotrophic Lifestyle of Powdery Mildew Fungi.

ABSTRACT: Obligate biotrophic plant pathogens like the powdery mildew fungi commit to a closely dependent relationship with their plant hosts and have lost the ability to grow and reproduce independently. Thus, at present, these organisms are not amenable to in vitro cultivation, which is a prerequisite for effective genetic modification and functional molecular studies. Saprotrophic fungi of the family Arachnopezizaceae are the closest known extant relatives of the powdery mildew fungi and may hold great potential for studying genetic components of their obligate biotrophic lifestyle. Here, we established telomere-to-telomere genome assemblies for two representatives of this family, Arachnopeziza aurata and A. aurelia. Both species harbour haploid genomes that are composed of 16 chromosomes at a ge
