New preprint featuring my favorite maize-relatives, the Andropogoneae! We sequenced the genomes of 27 species, including lemongrass, kangaroo grass, little and big bluestem, and more -- key species that shape grasslands and prairies worldwide. www.biorxiv.org/content/10.1...

On top, five Andropogoneae grass species, from left to right Zea mays subsp. mays, Hemarthria uncinata, Miscanthus sinensis, Sorghum bicolor, Andropogon gerardi. On bottom, a map of the world, with collection sites of Andropogoneae grasses in points. A green background shows the distribution of Andropogoneae grasses throughout tropical and temperate latitudes

On left, a phylogeny of Andropogoneae species, with 14 independent polyploidy origins noted. On right, genome size and repeat content of each assembly. Across all assemblies, average assembly size is 1.9 Gb, and average repeat size is 1.5 Gb.
