The complete chloroplast genome sequence of Thrixspermum amplexicaule (Orchidaceae, Aeridinae)

Abstract

: The complete chloroplast genome sequence of Thrixspermum amplexicaule was assembled and analyzed in this work. The total chloroplast genome size of T. amplexicaule was 148,124 bp in length, containing a large single-copy (LSC) region of 86,079 bp, a small single-copy (SSC) region of 10,799 bp, and a pair of inverted repeat (IR) regions of 25,623 bp. The GC content of T. amplexicaule was 36.4%. It encoded a total of 120 unique genes, including 75 protein-coding genes, 37 tRNA genes, and eight rRNA genes. The results of phylogenetic analysis strongly supported that all four samples of Thrixspermum are monophyletic and T. amplexicaule was closely related to T. centipeda .
