The complete chloroplast genome of Magnolia delavayi, a threatened species endemic to Southwest China.


ABSTRACT: Magnolia delavayi, a threatened plant endemic to Southwest China, is of great importance for landscaping because of its lotus-like creamy flowers. In this study, the complete chloroplast (cp) genome of M. delavayi was assembled based on the Illumina sequences. The cp genome of M. delavayi was 159,470?bp in length and contained a pair of inverted regions (IR, 26,409?bp) which were separated by the small single copy (SSC, 18,760?bp) and the large single copy (LSC, 87,892?bp) regions. It encoded 132 genes including 86 protein-coding genes, 37 tRNA genes, and eight rRNA ribosomal genes. The overall AT content of M. delavayi cp genome is 60.7%. The maximum likelihood phylogenetic analysis revealed that the species of M. delavayi was isolated first among the genus Magnolia. This result will be helpful for the conservation and phylogeny programs of the genus Magnolia.
