Abstract
Tainia cordifolia is a subtropical plant with significant ornamental value. Herein, we determined the complete chloroplast (cp) genome sequence of T. cordifolia using Illumina sequencing data. The whole cp genome is 158,089 bp in size, consisting of a pair of inverted repeats (IR 25,260 bp), a large single-copy region (LSC 86,876 bp), and a small single-copy region (SSC 20,693 bp). Plastid genome contains 136 genes, 88 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. What is more, a maximum-likelihood phylogenetic analysis demonstrated that T. cordifolia was most closely related to Oberonia japonica and Dendrobium salaccense. The cp genome will provide reference for the further investigation and research of T. cordifolia.
