Here we present a plastome phylogenomic analysis of 250 complete plastomes (179 genera) sampled from 44 of the 52 tribes of Poaceae. Plastome sequences were determined from high throughput sequencing libraries Submitted 8 August 2017 and the assemblies represent over 28.7 Mbases of sequence data. Phylogenetic signal Accepted 8 January 2018 Published 2 February 2018 was characterized in 14 partitions, including (1) complete plastomes; (2) protein coding regions; (3) noncoding regions; and (4) three loci commonly used in single Corresponding authors Jeffery M.
