Genome sequence resources for four phytopathogenic fungi from the Colletotrichum orbiculare species complex.

Colletotrichum orbiculare species complex fungi are hemibiotrophic plant pathogens that cause anthracnose of field crops and weeds. Members of this group have genomes that are remarkably expanded relative to other Colletotrichum fungi and compartmentalized into AT-rich, gene poor and GC-rich, gene rich regions. Here we present an updated version of the Colletotrichum orbiculare genome, as well as draft genomes of three other members from the C. orbiculare species complex; the alfalfa pathogen Colletotrichum trifolii, the prickly mallow pathogen Colletotrichum sidae and the burweed pathogen Colletotrichum spinosum. The data reported here will be important for comparative genomics analyses to identify factors that play a role in the evolution and maintenance of the expanded, compartmentalized genomes of these fungi which may contribute to their pathogenicity.
