The complete chloroplast genome sequence of the medicinal and economic plant woad Isatis indigotica (Brassicaceae).

ABSTRACT: Chloroplast (cp) genome sequences provide a valuable source for phylogenetic analysis. It becomes a popular useful tool for population and phylogeny in recently report. Here, the complete chloroplast genome of the Isatis indigotica has been reconstructed from the whole-genome Illumina sequencing data. The circular genome is 156,670?bp in size and comprises a pair of inverted repeat (IR) regions of 26,995?bp each, a large single-copy (LSC) region of 84,907?bp and a small single-copy (SSC) region of 17,773?bp. The total GC content is 36.5%, while the corresponding values of the LSC, SSC and IR region are 34.2%, 29.7% and 42.3%, respectively. The chloroplast genome contains 140 genes, including 94 protein-coding genes. The phylogenetic analysis showed a strong sister relationship with Raphanus sativus in Brassicaceae. These findings provide a foundation for further investigation of cp genome evolution in I. indigotica and other higher plants.
