The complete chloroplast genome and phylogenetic analysis of Ocimum kilimandscharicum Gurke (Camphor Basil) from India

摘要

Ocimum kilimandscharicum Gurke commonly known as Camphor Basil, is a medicinal plant species that belongs to the Lamiaceae family. Here, the sequencing and characterization of complete chloroplast genome sequence of O. kilimandscharicum is reported for the first time using Illumina paired-end sequencing data. The size of the chloroplast (cp) genome is 151,741?bp in length, with a large single-copy (LSC) region of 82,882?bp and a small single-copy (SSC) region of 17,587?bp, separated by a pair of 25,636?bp inverted repeat (IR) regions. There are 135 predicted genes, including 90 protein-coding genes, 37 transfer RNA (tRNA) genes, and eight ribosomal RNA (rRNA) genes in the genome, and the overall GC content of the genome is 37.9%. The phylogenetic analysis based on the chloroplast genome data indicated that O. kilimandscharicum is closer to O. tenuiflorum and clustered to other Ocimum species in Lamiaceae.
