The Ustilago maydis genome sequence, assembly, and annotation displayed in Map Viewer (build 1.1) is based on the U. maydis strain 521 genome provided by the Broad Institute. The Broad Institute sequenced the U. maydis genome at 10X coverage using whole genome shotgun (WGS) sequencing. They assembled the sequence into 274 nuclear genome contigs and annotated the genome assembly using automated gene prediction tools.

The U. maydis haploid genome is approximately 20.5 Mb, organized in 23 chromosomes.

The NCBI Map Viewer provides graphical displays of features on the U. maydis genome sequence assembly. Map features that can be seen along the sequence include NCBI contigs, genes, RefSeq transcripts, and GenBank genomic sequences. You can find features of interest by submitting a query against the whole genome or against one chromosome at a time. Results are indicated both graphically, as tick marks on the ideogram, and in a tabular format. The results table includes links to a chromosome graphical view, where the feature can be seen in the context of additional data. You can also browse a chromosome by clicking on a chromosome link in the ideogram above. Use the "Maps & Options" window, available on individual chromosome displays, to configure your display. Extensive documentation and tutorials are provided to describe the resource.

U. maydis is a pathogenic fungus that causes corn smut disease, a disease of maize and teosinte that results in severe damage to the plants and great losses of corn crops every year. However, in Mexico and Central America, corn smut is considered a culinary delicacy known as huitlacoche. U. maydis is an excellent model system for studying host-pathogen interactions, and it has been studied for more than 100 years by plant pathologists.
