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

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.

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

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.

The complete chloroplast genome of the endangered plant Paphiopedilum wardii (Orchidaceae).

Chloroplast (cp) genome sequences provide a valuable source for phylogenetic analysis, which becomes a popular tool for population and phylogeny in a recent report. Here, the complete chloroplast genome of the Paphiopedilum wardii has been reconstructed from the whole-genome Illumina sequencing data. The circular genome is 169,820 bp in size and comprises a pair of inverted repeat (IR) regions of 33,641 bp each, a large single-copy (LSC) region of 98,872 bp and a small single-copy (SSC) region of 3666 bp. The total GC content is 33.8%, while the corresponding values of the IR regions, LSC, and SSC and are 38.7%, 31.7% and 26.7%, respectively. The chloroplast genome contains 151 genes, including 91 protein-coding genes, eight ribosomal RNA genes and 52 transfer RNA genes. Two genes (ndhA and ndhB) are pseudogenized or lost in its cpDNA.
