The complete chloroplast genome sequence of Pellacalyx yunnanensis: an endangered species in China

Pellacalyx yunnanensis is an endangered plant species occurring in Yunnan province of China. The first complete chloroplast genome (cpDNA) sequence of P. yunnanensis was determined from Illumina HiSeq pair-end sequencing data in this study. The cpDNA is 163,743 bp in length, contains a large single-copy region (LSC) of 91,075 bp and a small single-copy region (SSC) of 18,668 bp, which were separated by a pair of inverted repeats (IR) regions of 27,000 bp. The genome contains 128 genes, including 83 protein-coding genes, 8 ribosomal RNA genes, and 37 transfer RNA genes. The overall GC content of the whole genome is 35.7%, and the corresponding values of the LSC, SSC, and IR regions are 33.0%, 29.6%, and 42.3%, respectively. Further phylogenomic analysis showed that P. yunnanensis clustered in a unique clade in family Rhizophoraceae.
