MaizeGDB hosts 18 genomes. To learn more about contributing your genome to MaizeGDB, click here.

This search form allows you to enter basic information (e.g., cultivar, genome accession), including partial names, to search for a genome assembly.
Use the wildcards '%' or '*' to find matches that contain your search term. '^' at the beginning of search term will find matches that start with that term. '$' at the end of search term will find matches that end with that term.

Genome assembly nomenclature
Genome assemblies are named according to the following formula:
   [species abbreviation]-[cultivar or accession]-[quality]-[provider].[version]
   Zm-B73-REFERENCE-GRAMENE-4.0 (B73 reference genome version 4, from Gramene),
   Zx-PI566673-REFERENCE-YAN-1.0 (Zea mays spp. mexicana, PI 566673, reference genome version 1, from the Yan lab)

Genome identifiers are shorter versions used as prefixes to gene model identifiers. They take the form:
   [species abbreviation][5 digits]
   Zm0004d (Zm-B73-REFERENCE-GRAMENE-4.0)
   Zx0001a (Zx-PI566673-REFERENCE-YAN-1.0)

Annotation identifiers are built from genome identifiers:
   [genome identifer].[version]
   Zm0004d.2 (Zm-B73-REFERENCE-GRAMENE-4.0)
   Zx0001a.1 (Zx-PI566673-REFERENCE-YAN-1.0)

See the Genome Nomemclature Guidelines for more information.
Genome assemblies at MaizeGDB
MaizeGDB hosts all Zea mays genome assemblies that meet a minimum set of requirements. See more information about submitting a genome assembly to MaizeGDB here.

MaizeGDB provides three levels of support:
Full: Metadata, BLAST targets, downloads, browser, gene pages, synteny with B73 gene models.
Medium: Metadata, BLAST targets, downloads.
Basic: Metadata only.
Definition of terms
Draft genome
Genome has been sequenced and assembled into contigs, but contigs have not been assembled into pseudomolecules.
Data about data. Metadata for genome assemblies includes information about the plant that was sequenced, methods used, data providers and contributers, downloads, and more.
Reference genome
Genome has been completely sequenced and assembled into pseudomolecules.

See the right-hand side bar for more terms and explanations.
