Abstract
Tapiscia sinensis (Tapisciaceae) is an ancient and endangered tree endemic to China. Its phylogenetic position is of importance to the study of plant evolution. The complete chloroplast (cp) genome of T. sinensis was assembled using Illumina pair-end sequencing data. The circular cp genome is 161,100 bp long, including a pair of inverted repeat (IRs) regions of 27,407 bp, a large single copy (LSC) region of 87,766 bp and a small single copy (SSC) region of 18,520 bp. It encodes 131 genes, including 85 protein-coding genes (77 PCG species), 38 transfer RNA genes (30 tRNA species), and 8 transfer RNA genes (4 rRNA species). Fifteen genes harbor a single intron, while another three genes have a couple of introns. Entire T. sinensis cp genome, LSC, SSC and IR regions contain 37.2, 35.2, 31.0 and 42.4% GC, respectively. Phylogenetic analysis based on the concatenated coding sequences of cp PCGs suggests that T. sinensis is more closely related to the Sapindales than to the Malvales.
