The complete chloroplast genome sequence of Lavandula angustifolia (Lamiaceae), an introduced aromatic plant growing in China

The chloroplast genome of 'Jingxun 2,' a new cultivar of Lavandula angustifolia, was sequenced in view of its role as an economically important aromatic plant with wide applications. De novo assembly with whole genome sequencing data completed the chloroplast genome (cp genome) of 151,459 bp in length, which included two inverted repeats (IRs) blocks of 25,467 bp, separated by the large single-copy (LSC) block of 82,945 bp and small single-copy (SSC) block of 17,580 bp. The genome encoded 123 genes consisting of 86 protein-coding genes, 29 tRNA genes, and 8 rRNA genes. The overall AT content of L. angustifolia cp genome is 62.04%. The AT contents of the LSC, SSC, and IR regions were 64.05, 68.14, and 56.66%, respectively. Further, a maximum-likelihood (ML) phylogenetic tree was reconstructed to indicate relationships among taxa Lamiaceae. The complete chloroplast genome of L. angustifolia provides utility information for aromatic plants evolutionary and genomic studies.
