Updates to the Zea mays reference assembly

Since publishing the initial assembly of the reference strain (B73) in 2008, the maize sequencing project has released two updates. The initial assembly and RefGen_v2 are based on a BAC (bacterial artificial chromosome) sequencing strategy. RefGen_v2 included ~2000 updated BAC sequences and improved upon the initial assembly by resolving overlaps between BACs in the minimum tiling path to define the 10 chromosome pseudomolecules.

Improved GRMZM5G891969 gene model. A denovo contig provided two missing exons needed to merge two apparently distinct gene models (GRMZM5G823855 and GRMZM5G891969) into a single model that is conserved in sorghum (Sb01g050450).

Deprecation of maizesequence.org

The maize sequencing project had been running an EnsEMBL based genome browser, comparative analysis tools, and biomart at maizesequence.org, but this responsibility been transferred to gramene.org. Gramene hosts the current maize B73 reference genome sequence (RefGen_v3) and annotations along with regularly updated database cross references and comparative analyses provided by Gramene and collaborators at plants.ensembl.org.
