The AGP B73v4 genome has officially been published and released. To convert between the old GRMZM annotations and the new B73v4 Zm annotations you may use our translation tool or download the full gene model associations list between B73v3 and all other assemblies in our database.
We would like to remind the maize community that under the Toronto Agreement, whole-genome research on the B104 genome assembly may not be submitted for publication until the official B104 genome paper is published.
