Abstract

Tanakaea radicans is classified in the monotypic genus Tanakaea in the Saxifragaceae. It is a small, evergreen plant with a disjunct distribution in Japan and China. Here, we report and characterize for the first time the complete plastid genome sequence of T. radicans. The chloroplast genome is 155,265 bp in length and contains a pair of inverted repeats (25,794 bp) separated by a large single copy (86,289 bp) and a small single copy (17,388 bp). A total of 113 unique genes, including 79 protein-coding, 30 tRNA, and four rRNA genes, were annotated. Phylogenetic analysis showed that T. radicans was sister to Leptarrhena pyrolifolia within Huecheroids linage of Saxifragaceae.

Keywords: Complete chloroplast genome; Huecheroids; Leptarrhena; Saxifragaceae; Tanakaea.
