Was so great to have the assembly of a member of sister tribe Paspaleae to use as an outgroup. Thanks!

Reclassified to Anatherum virginicum in 2023! Sorry to you and Linnaeus www.tandfonline.com/doi/full/10....
Reinstatement and expansion of the genus Anatherum (Andropogoneae, Panicoideae, Poaceae)
The genus Andropogon sensu lato is known to be polyphyletic. Accordingly, we here adjust part of the classification of the genus to reflect its evolutionary history and morphological diversity. A p...

A monumental effort -- huge thanks to everybody involved! And see what individual plants and their genomes look like here: mcstitzer.github.io/panand_assemblies

We're not entirely sure why Andropogoneae resist the commonly observed patterns that follow polyploidy, but check out the preprint for our thoughts!

Instead, we see a surprising lack of genome evolution in Andropogoneae polyploids: they retain almost all chromosomes, keep most genes, and their TEs only sometimes expand.

We uncovered 14 independent origins of polyploidy in these grasses, and expected to see patterns similar to those observed in maize: a reduction in chromosome number, the loss of duplicate genes, and bursts of transposable element activity.
