Investigation of mitochondrial-derived plastome sequences in the Paspalum lineage (Panicoideae; Poaceae).

ABSTRACT:

Background

The grass family (Poaceae), ca. 12,075 species, is a focal point of many recent studies that aim to use complete plastomes to reveal and strengthen relationships within the family. The use of Next Generation Sequencing technology has revealed intricate details in many Poaceae plastomes; specifically the trnI - trnL intergenic spacer region. This study investigates this region and the putative mitochondrial inserts within it in complete plastomes of Paspalum and other Poaceae.

Results

Nine newly sequenced plastomes, seven of which contain an insert within the trnI - trnL intergenic spacer, were combined into plastome phylogenomic and divergence date analyses with 52 other species. A robust Paspalum topology was recovered, originating at 10.6 Ma, with the insert ari
