The complete chloroplast genome sequence of the fragrant plant Lavandula angustifolia (Lamiaceae)

摘要

Chloroplast (cp) genome sequences have become a useful popular tool for population and phylogeny recently. It is little known about genetics information of Lavandula angustifolia. Here, the complete chloroplast genome of the L. angustifolia has been reconstructed from the whole-genome Illumina sequencing data. The circular genome is 153,448 bp in size, and comprises of a pair of inverted repeat (IR) regions of 25,632 bp each, a large single-copy (LSC) region of 84,588 bp and a small single-copy (SSC) region of 17,596 bp. The total GC content is 38.0%, while the corresponding values of the LSC, SSC, and IR regions are 36.2, 31.8, and 43.2%, respectively. The chloroplast genome contains 132 genes, including 88 protein-coding genes, 8 ribosomal RNA genes, and 37 transfer RNA genes. The Maximum-Likelihood phylogenetic analysis showed a strong sister relationship with Salvia miltiorrhiza in Lamiaceae. These findings provide a foundation for further investigation of cp genome evolution in L. angustifolia and other higher plants.
