Chloroplast genome data of five species: Clarifying genome structure and phylogenetic relationships.

species have considerable ecological and economic value, however, the phylogenetic relationships among remain controversy. In this study, we sequenced and assembled the chloroplast (cp) genomes of five species: , and . We then conducted comparative genomic analyses and constructed their phylogenetic relationships. The genome length ranged from 157,870 to 158,451 bp, and 131 genes were annotated (86 protein-coding genes, 37 tRNAs, and 8 rRNAs). Additionally, 49-57 simple sequence repeats were detected, with most in the large single-copy region and with AT base preferences. Comparative genomic analyses revealed high similarities in structure, order, and gene content. However, we identified four highly divergent sequences: ---, and -. The phylogenomic relationship analysis suggested that the species were grouped together, in which , and were categorized into a branch, and were clustered a branch. This study provides an improved understanding of the genetic relationships among the and provides a basis for the development and utilization of resources.
