Plastomes of nine hornbeams and phylogenetic implications.

ABSTRACT: Poor phylogenetic resolution and inconsistency of gene trees are major complications when attempting to construct trees of life for various groups of organisms. In this study, we addressed these issues in analyses of the genus Carpinus (hornbeams) of the Betulaceae. We assembled and annotated the chloroplast (cp) genomes (plastomes) of nine hornbeams representing main clades previously distinguished in this genus. All nine plastomes are highly conserved, with four regions, and about 158-160 kb long, including 121-123 genes. Phylogenetic analyses of whole plastome sequences, noncoding sequences, and the well-aligned coding genes resulted in high resolution of the sampled species in contrast to the failure based on a few cpDNA markers. Phylogenetic relationships in a few clades based
