Abstract

The nucleotide sequences of the two chloroplast (cp) genomes from Pogostemon stellatus and Pogostemon yatabeanus are the first to be completed in genus Pogostemon of family Lamiaceae. The structure of two Pogostemon cp genomes shows similar characteristic to the typical cp genome of angiosperms. The lengths of two cp genomes are 151,825bp and 152,707 bp, respectively. Two cp genomes are divided into LSC region (83,012 bp and 83,791 bp) and SSC region (17,524 bp and 17,568 bp) by two IR regions (25,644 bp and 25,674 bp). Both of two cp genomes contain 114 genes (80 protein-coding genes, 30 tRNA genes and 4 rRNA genes), 10 protein-coding genes and 7 tRNA genes duplicated in the IR regions. Similar to the typical cp genome of angiosperms, 18 of the genes in the Pogostemon cp genome have one or two introns. The overall A-T contents of two genomes are 61.8% which is also similar to general angiosperms. The A-T content in the non-coding (64.4%) is higher than in the coding (59.9%) regions. Sixty-seven and seventy-three simple sequence repeat (SSR) loci were identified in the P. stellatus and P. yatabeanus cp genomes, respectively. In phylogenetic analysis, genus Pogostemon shows closed relationship with Scutellaria baicalensis of Scutellarioideae.
