The chloroplast genome of Paeonia decomposita (Paeoniaceae), an endangered wild tree peony from Sichuan, China

摘要

Paeonia decomposita (Paeoniaceae) is an endangered wild tree peony endemic to northwestern Sichuan, China. It was categorized as Endangered' in the IUCN category and one of the National Key Protected Wild Plants (Class 2). Here we assemble and annotate the complete chloroplast genome of P. decomposita from Illumina paired-end sequencing data. The chloroplast genome size of P. decomposita is 152,601bp, containing a pair of inverted repeats of 25,650bp, a small single copy of 17,036bp and a large single copy of 84,265bp. The overall GC content of the chloroplast genome is 38.38%. A total of 129 genes were annotated, including 82 protein-coding genes, 39 tRNA genes and eight rRNA genes. In addition, phylogenetic analysis of ten selected chloroplast genomes revealed that P. decomposita was sister to the clade including P. ludlowii and P. delavayi.
