Arachnopeziza aurata strain:CBS127674 Genome sequencing

Fungi of the family Arachnopezizaceae are the closest known living relatives of the powdery mildew fungi and may hold great potential for studying genetic components of their obligate biotrophic life style. Here, we established the first genetic modification protocols for two species of this family, Arachnopeziza aurata and A. aurelia. We first assembled their genomes telomere-to-telomere and found that both species have 16 chromosomes at a genome size of 43.1 and 46.3 million base-pairs, respectively, which show relatively conserved structure and, in contrast to the transposon-enriched powdery mildew genomes, a repeat content below 6%.
