Background  Comparisons between C 3  and C 4  grasses often utilize C 3  species from the subfamilies Ehrhartoideae or Pooideae and C 4  species from the subfamily Panicoideae, two clades that diverged over 50 million years ago. The divergence of the C 3  panicoid grass  Dichanthelium oligosanthes  from the independent C 4  lineages represented by  Setaria viridis  and  Sorghum bicolor  occurred approximately 15 million years ago, which is significantly more recent than members of the Bambusoideae, Ehrhartoideae, and Pooideae subfamilies.  D. oligosanthes  is ideally placed within the panicoid clade for comparative studies of C 3  and C 4  grasses.    Results  We report the assembly of the nuclear and chloroplast genomes of  D. oligosanthes , from high-throughput short read sequencing data and a comparative transcriptomics analysis of the developing leaf of  D. oligosanthes ,  S. viridis , and  S. bicolor . Physiological and anatomical characterizations verified that  D. oligosanthes  utilizes the C 3  pathway for carbon fixation and lacks Kranz anatomy. Expression profiles of transcription factors along developing leaves of  D. oligosanthes  and  S. viridis  were compared with previously published data from  S. bicolor ,  Zea mays , and  Oryza sativa  to identify a small suite of transcription factors that likely acquired functions specifically related to C 4  photosynthesis.    Conclusions  The phylogenetic location of  D. oligosanthes  makes it an ideal C 3  plant for comparative analysis of C 4  evolution in the panicoid grasses. This genome will not only provide a better C 3  species for comparisons with C 4  panicoid grasses, but also highlights the power of using high-throughput sequencing to address questions in evolutionary biology.
