Abstract:
Rhamnus leptacantha C.K.Schneid. (1914). is a rare shrub species of the genus Rhamnus. The complete plastid genome of Rhamnus leptacantha was sequenced for the first time in this study. The total length of this genome is 161,248 bp with a large single copy (LSC) region (89,386 bp), a small single copy (SSC) region (19,000 bp), and two inverted repeat regions (IRs, 26,431 bp). A total of 133 functional genes were annotated, including 88 protein-coding genes, 37 tRNA genes and 8 rRNA genes. Plastome of R. leptacantha displayed a conservative structure and gene order. Phylogenetic analysis strongly supported R. leptacantha clustered with other members of genus Rhamnus. This study provides a foundation for further investigation of the complete chloroplast genome in inferring the evolution within the Rhamnaceae family.
