Characterization of the complete chloroplast genome of Pinus wangii (Pinaceae), an endangered and endemic species in China

Abstract

The complete cp genome of Piuns wangii was 117,014 bp in size, containing a large single copy (LSC, 64,061 bp) region and a small single copy (SSC, 52,007 bp) region separated by two reduced inverted repeats (IRs, 473 bp). A total of 107 genes were predicted, including 73 protein-coding genes, 30 tRNA genes, and 4 rRNA genes. Most of the 51 simple sequence repeats (SSRs) were mononucleotides motifs of A/T types and were found to be located in non-coding regions. Phylogenetic analysis of Asian Pinus showed P. wangii clustered a strongly-supported clade with Pinus morrisonicola, Pinus sibirica, Pinus wallichiana, and Pinus pumila.
