The complete chloroplast genome of Ocimum gratissimum from India - a medicinal plant in the Lamiaceae.

ABSTRACT: Ocimum gratissimum L. is an important medicinal species with several therapeutic applications. It is used in traditional medicine as a single drug and in formulations. We generated the complete chloroplast genome sequence of O. gratissimum by using Illumina paired-end sequencing data. The O. gratissimum chloroplast genome is 152,469 bp in length, containing a large single copy (LSC) region of 83,614 bp and a small single copy region (SSC) of 17,607 bp, separated by a pair of inverted repeats (IRs) of 25,624 bp. The genome contains 138 unique genes, including 85 protein-coding, 45 tRNA, and eight rRNA genes. Among them, six genes have one intron each, and two genes contain two introns. The overall GC content of the chloroplast genome is 37.8%, while the corresponding values of LSC, SSC, and IR regions are 35.6%, 31.7%, and 43.2%, respectively. Phylogenetic analysis with the complete chloroplast genomes of other related species revealed that O. gratissimum is fully resolved in a clade with other Ocimum species classified to the family Lamiaceae.

The complete chloroplast genome sequence of the medicinal plant Salvia miltiorrhiza.

Project description:Salvia miltiorrhiza is an important medicinal plant with great economic and medicinal value. The complete chloroplast (cp) genome sequence of Salvia miltiorrhiza, the first sequenced member of the Lamiaceae family, is reported here. The genome is 151,328 bp in length and exhibits a typical quadripartite structure of the large (LSC, 82,695 bp) and small (SSC, 17,555 bp) single-copy regions, separated by a pair of inverted repeats (IRs, 25,539 bp). It contains 114 unique genes, including 80 protein-coding genes, 30 tRNAs and four rRNAs. The genome structure, gene order, GC content and codon usage are similar to the typical angiosperm cp genomes. Four forward, three inverted and seven tandem repeats were detected in the Salvia miltiorrhiza cp genome. Simple sequence repeat (SSR) analysis among the 30 asterid cp genomes revealed that most SSRs are AT-rich, which contribute to the overall AT richness of these cp genomes. Additionally, fewer SSRs are distributed in the protein-coding sequences compared to the non-coding regions, indicating an uneven distribution of SSRs within the cp genomes. Entire cp genome comparison of Salvia miltiorrhiza and three other Lamiales cp genomes showed a high degree of sequence similarity and a relatively high divergence of intergenic spacers. Sequence divergence analysis discovered the ten most divergent and ten most conserved genes as well as their length variation, which will be helpful for phylogenetic studies in asterids. Our analysis also supports that both regional and functional constraints affect gene sequence evolution. Further, phylogenetic analysis demonstrated a sister relationship between Salvia miltiorrhiza and Sesamum indicum. The complete cp genome sequence of Salvia miltiorrhiza reported in this paper will facilitate population, phylogenetic and cp genetic engineering studies of this medicinal plant.
