The complete plastome of Cymbidium tortisepalum (Orchidaceae) hermaphrodite

Abstract

We report a complete chloroplast (cp) genome of a Cymbidium tortisepalum hermaphrodite. The cp genome is 149,764 bp in length, with a large single-copy region (LSC) of 85,257 bp and a small single-copy region (SSC) of 13,317 bp, which were separated by a pair of 25,595 bp inverted repeat regions (IRs). The genome contained 130 genes, with 111 unique genes, including 77 protein-coding genes, 30 tRNA genes, and 4 rRNA genes. The overall GC content is 37.11% with the values of the LSC, SSC, and IR regions are 34.44%, 29.67%, and 43.49%, respectively. Further, phylogenetic analysis suggested that the plastome of C. tortisepalum hermaphrodite is close to published C. sinense (NC021430.1), C. kanran (KU179435.1), C. tortisepalum (NC021431.1), and C. ensifolium (NC028525.1) plastomes.
