Technical Abstract: In January 2020, the NAM sequencing consortium released through MaizeGDB the high-quality genome assemblies of the 25 NAM founders and version 5 of the B73 assembly. These 26 assemblies were sequenced using consistent technologies and methods, creating a set of maize genome assemblies that is more amenable to comparative analysis than groups of assemblies of varying quality, generated through different technologies and methods. At the same time, preliminary annotations for all 26 genomes were also released. These annotations were provided so that maize researchers could begin to explore the new assemblies, but with the warning that they should not be used for published research. In January, 2021, the official annotations for all 26 assemblies were released, replacing the preliminary annotations. The 2021 data release also includes new methylation, TE annotations, structural variants, and RNA-seq data for the 26 assemblies. Here we describe the official annotations and how they differ from the preliminary annotations, the NAM founder assemblies, the TE, SV, and RNA-seq analyses, and where to find their information and data at MaizeGDB.
