Phylogenetic analysis of the chloroplast genome for Magnolia liliflora (Magnoliaceae), an endemic species to China

Magnolia liliflora is commonly called lily magnolia and its buds are used as the herbal medicine; it is an endemic species to China. In this study, the complete chloroplast genome of M. liliflora has been presented and annotated. The whole chloroplast (cp) genome is 158,177 bp in size, which exhibits a large single-copy region (LSC) of 88,134 bp, a small single-copy region (SSC) of 19,876 bp and two inverted-repeat regions (IRs) 25,706 bp in each one. The overall nucleotide composition is: 30.0% of A, 30.9% of T, 19.9% C, and 19.2% G, with the GC content of the chloroplast genome 39.1%. The cp genome of M. liliflora contains 129 genes, which includes 86 protein-coding genes (PCGs), 35 transfer RNA (tRNAs), and 8 ribosome RNA (rRNAs). The maximum-likelihood (ML) tree result showed that M. liliflora is closely related to two Magnoliaceae family species of M. dealbata and M. glaucifolia in phylogenetic relationship. This complete chloroplast genomes will be useful for medicinal study in the future.
