Comparative chloroplast genome analyses of <i>Oxytropis</i> DC. species: new insights into genome evolution and phylogenomic implications.

ABSTRACT: The genus Oxytropis DC. comprises about 310 species distributed in Asia, Europe, and North America. Previous studies based on evidences from morphology or a few molecular markers are helpful for understanding the classification and systematic evolution of Oxytropis. However, a scarcity of chloroplast genomic resources for Oxytropis has hindered the understanding of the genus's systematic classification and chloroplast genome evolution. Here comparative genomic analyses were conducted on chloroplast genomes of 24 Oxytropis species. Chloroplast genomes of Oxytropis species showed the triad structure due to the loss of one copy of the IR, with the size range from 121854 bp to 125271 bp. The Oxytropis cp genomes encoded a total of 110 genes, including
