Strain521 / FGSC 9021

Genome assembly and annotationi GCA_000328475.2 from ENA/EMBL

Ustilago maydis, commonly known as corn smut, belongs to the order Ustilaginales in the phylum Basidiomycota. As a biotroph, it is of economic importance due to its destructive potential as a plant pathogen. Infection of the host, maize, occurs through tissue above ground and can affect all tissues; the resulting galls are considered a delicacy called huitlacoche in Central America. U. maydis is an established model organism for studying plant-microbe interactions. The genome of strain 521 was published in 2006. It comprises about 21 Mb and almost 7,000 predicted protein-coding genes.
