摘要：Liriodendron chinense is a rare Tertiary relict tree species. In this study, we report the complete chloroplast genome of a Chinese tulip tree, L. chinense. The total genome size was 159,429 bp in length, containing a pair of inverted repeats (IRs) of 26,333 bp, separated by large single copy (LSC) and small single copy (SSC) of 87,766 and 18,997 bp, respectively. The chloroplast genome contained the conservative quadripartite structure present in most Magnoliaceae chloroplasts composing of 79 protein-coding genes, 30 tRNAs and 4 rRNAs. Among these genes, 15 harbored a single intron, and 2 contained a couple of introns. The overall G+C content of the cpDNA is 39.2 %, while the corresponding values of the LSC, SSC and IR regions are 37.8, 34.3 and 43.2 % respectively. A maximum likelihood phylogenomic analysis showed that L. chinense is closely related to L. tulipifera that belongs to the tribe Magnoliaceae.
