Characterization of the complete chloroplast genome of the medicinal plant Orixa japonica (Rutaceae) in Zhejiang Province and its phylogenetic analysis within family Rutaceae

摘要

Orixa japonica Thunb. is an important medicinal plant belonging to the family Rutaceae. In this study, we determined the the complete chloroplast (cp) genome of O. japonica , which was 158,525?bp in length containing one large single copy region (85,965?bp), one small single copy region (18,552?bp), and a pair of inverted repeat regions (27,004?bp each). A total of 134 genes were annotated in the cp genome, including 88 protein coding genes, 37 tRNA genes, eight rRNA genes, and one pseudo gene ycf1. According to the phylogenetic analysis, O. japonica clustered together with Casimiroa edulis with high bootstrap value, indicating a close genetic relationship with subfamily Amyridoideae.
