The genome sequence and gene prediction of Oculimacula yallundae CBS 49480 have not been determined by the Joint Genome Institute (JGI), but were downloaded from CSFG on July 31, 2022. In order to allow comparative analyses with other fungal genomes sequenced by the JGI, a copy of this genome is incorporated into Mycocosm. Please note that this copy of the genome is not automatically updated. JGI tools were used to automatically annotate predicted proteins.

Oculimacula yallundae (Pseudocercosporella herpotrichoides var. herpotrichoides), basionym Tapesia yallundae, anamorph Helgardia herpotrichoides, is the agent causing foot-rot disease in cereals and grasses (1,2). Found worldwide, it prefers cool damp weather, wet soil and it has a growth temperature optimum between 20-23 ºC (2). Two main pathotypes of the fungus are present in field populations: W-type and R-type. W-type is usually more pathogenic to wheat seedlings than to rye while R-type is equally pathogenic for these species) (1,3). Enzymes involved in the degradation of hemicellulose, cellulose and pectin has been characterized (4-6). The genomic sequence of O. yallundae will provide new information to understand pathogenic fungi.
