The complete plastid genome of Thrixspermum centipeda (Orchidaceae, Aeridinae)

Abstract

The complete plastid genome of the type species of Thrixspermum, Th. centipeda, was determined and analyzed in this work. The plastome was 147,888 bp in length with 85,899 bp of the large single-copy (LSC) region, 11,055 bp of the small single-copy (SSC) region and 25,467 bp of the invert repeats (IR) regions. The genome contained 120 genes, including 74 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. Phylogenetic analysis divided 18 Aeridinae plastomes into four groups, and Th. centipeda was sister to Th. tsii.
