Abstract

Magnolia coriacea, Chang et B. L. (Magnoliaceae) is a critically endangered tree, endemic to Yunnan province, China. In this study, the complete chloroplast genome of M. coriacea was sequenced and analyzed. The total chloroplast genome size of M. coriacea is 160,113 bp, including a pair of inverted repeat regions (IRs, 26,576 bp) separated by a large single-copy (LSC, 88,175 bp) region and a small single-copy region (SSC, 18,786 bp). The complete chloroplast genome contains 86 protein-coding (PCGs), 37 transfer RNA (tRNAs), and 8 ribosomal RNA (rRNAs) genes. The phylogenetic analysis showed that M. coriacea is closely related to M. cathcartii. This study contributes to the bioinformatics on the evolution, genetic, conservation, and molecular biology for future studies of Magnoliaceae.
