Abstract
The complete nucleotide sequence of the Premna microphylla Turcz chloroplast (cp) genome was reported and characterized in this study. The cp genome is 155,293 bp in length, with 62.13% AT content. A pair of 25,763 bp inverted repeat regions (IR) are separated by 86,078 bp large single-copy regions (LSC) and a 17,689 bp small single-copy regions (SSC). The cp genome encodes 133 predicted functional genes, 115 are individual (80 protein-coding genes, 31 tRNA genes, four rRNA) genes, 18 are duplicated in the IR regions and ycf1 gene extends into the IR region in the junctions between IR and SSC. Of 115 individual genes, 16 genes contain one intron and two genes have two introns.
