The plastid genome sequence of Neocinnamomum delavayi (Lec.) Liou

Abstract

Neocinnamomum delavayi (Lec.) Liou is a kind of medicinal plants belonging to the genus Neocinnamomum H. Liu, but is often confused with N. mekongense (Hand.-Mazz.) Kosterm. Here, the complete plastid sequence of the N. delavayi was determined. The length of the plastid genome is 150,584 bp with overall AT content of 61%. It exhibited a typical quadripartite structure comprising a large single copy region (LSC) of 91,887 bp, a small single copy region (SSC) of 18,443 bp, and a pair of inverted repeat regions (IRs) of 20,262 bp each. Maximum likelihood phylogenetic analysis with GTR + F+R2 model was performed using eighteen complete plastomes of the Lauraceae, which strongly supports the relationships: sisterhood of the N. delavayi and a clade containing N. mekongense and N. lecomtei Liou.
