The complete chloroplast genome of Rosemary (Rosmarinus officinalis)

Abstract

Rosemary (Rosmarinus officinalis) is a perennial herb with fragrant endemic to Mediterranean region. Despite its important economic values on flavour, food and medicinal industry, the whole chloroplast (cp) genome of it has not been reported yet. Here, the complete chloroplast genome of the R.officinalis has been reconstructed from the whole-genome Illumina sequencing data. The circular genome is 152,462 bp in size, and comprises a pair of inverted repeat (IR) regions of 25,569 bp each, a large single-copy (LSC) region of 83,355 bp and a small single-copy (SSC) region of 17,969 bp. The overall GC content of the cp genome was 38.0%. The chloroplast genome contains 132 genes, including 94 protein-coding genes, 30 transfer RNA genes, and eight ribosomal RNA genes. Phylogenomic analysis strongly supported the close relationship of R. officinalis and Scutellaria baicalensis.
