Preliminary phylogenetic relationships of Dichanthelium (Poaceae) as revealed through whole plastomes and nrDNA via genome skimming. The genus Dichanthelium is distributed throughout the Americas, and Hawaii, with its highest species diversity in the eastern United States. Species delimitation within the genus is contentious, and low levels of sequence divergence result in poor resolution with conventional molecular markers. Using Illumina HiSeq sequencing technology, we “genome skimmed” plastomes without enrichment. Coverage of plastomes averaged approximately 30x across species sampled and the full nuclear ribosomal complex was recovered. Based on these data, Dichanthelium is monophyletic and relationships show better resolution than with nrITS alone, although problematic aspects of species level relationships remain.
