Phylogenomics and plastome evolution of Lithospermeae (Boraginaceae).

ABSTRACT:

Background

Lithospermeae is the largest tribe within Boraginaceae. The tribe has been the focus of multiple phylogenetic studies over the last 15 years, with most focused on one genus or a few genera. In the present study, we newly sequenced 69 species of Lithospermeae and relatives to analyze the phylogenomic relationships among its members as well as the evolution of the plastid genome.

Results

The phylogeny of Lithospermeae resolved from the plastid genome and nrDNA cistron is generally congruent with prior studies, but is better resolved and supported. Increasing character sampling across the plastid genome results in gradually more similar trees to that from the entire plastid genome. Overall, plastid genome structure was quite consistent across Lithospermeae. Codon Usa
