Complete chloroplast genome sequence of an endangered tree species, Magnolia sieboldii (Magnoliaceae)

Abstract

The characteristic of complete chloroplast (cp) genome of Magnolia sieboldii, an endangered species in China, was first sequenced in this study. It showed a typical quadripartite structure with a length of 160,177 bp. It composed of a large single copy (LSC) region of 88,238 bp, a small single copy (SSC) region of 18,763 bp, and a pair of inverted repeat (IR) regions of 26,588 bp. Further maximum parsimony phylogenetic analysis was performed based on 38 complete plastomes from 30 magnoliids and basal angiosperm species. The result supported a close relationship among M. grandiflora, M. officinals, M. sieboldii, and M. tripetala.
