The Family Tree Of Corn

Branches not to scale. Tree designed in Mesquite.

Branches lengths not remotely to scale. Tree designed in Mesquite.

This family tree shows the relationship of a few of the species in the grass family tree that I think people might be most familiar with. Genomes that were published before today are marked in green (there were only two, sorghum and rice), the maize genome which was just published today is marked in yellow, and brachypodium (which you shouldn’t feel at ALL bad if you haven’t heard of) is marked in grey as its genome project is in the final stages (a draft assembly was released to the public last winter) so it’ll probably be the next grass genome to be published. After that I’m less sure, I know there’s a foxtail millet genome project, but I don’t have any idea how far along the process of genome sequencing, assembly and annotation the genome project is.
What’s important to know about the relationship of the sequenced grasses? (more…)
