The complete chloroplast genome of Hemiptelea davidii (Ulmaceae), the only species of the genus Hemiptelea

Abstract

Hemiptelea davidii (Hance) Planch is a potential valuable forest tree in China. Here, the complete chloroplast genome of H. davidii was reported using high-throughput sequencing technique. The chloroplast genome is 160,195 bp in length, contains a pair of inverted repeat regions (IR, 26,599 bp), which were separated by a large single copy region (LSC, 88,231 bp) and a small single copy region (SSC, 18,766 bp). The GC content of the whole chloroplast genome is 35.28%. The chloroplast genome comprises 111 unique genes, including 77 protein-coding genes, 30 tRNA genes, and four rRNA genes. Phylogenetic analyses of 17 chloroplast genomes indicated that H. davidii is close with Zelkova and Ulmus species in Ulmaceae but little far from the species in Cannabaceae, Moraceae and Urticaceae.
