Abstract: Liriodendron chinense is a rare Tertiary relict
tree species. In this study, we report the complete chloro-
plast 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 pro-
tein-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.
