The complete chloroplast genome of Craigia yunnanensis, an endangered plant species with extremely small populations (PSESP) from South China

摘要

Craigia yunnanensis is an Endangered tree species, enlisted in the national plant species with extremely small population (PSESP) of China for urgent protection. The chloroplast genome is characterized using Illumina pair-end sequencing data. The whole chloroplast genome is 163,166?bp in length and consists of a pair of inverted repeat (IR) regions of 25,573?bp each, which are separated by the large single copy (LSC: 91,580?bp) region and small single copy (SSC: 20,440?bp) regions. The chloroplast genome encodes 113 unique genes, including 79 protein-coding genes (PCGs), 30 tRNA, and 4 rRNA genes. The overall GC content of the whole chloroplast genome is 36.4%. The phylogenetic tree revealed a close relationship between C. yunnanensis and Tilia species of Malvaceae family.
