The chloroplast genome of aromatic plants Cinnamomum pauciflorum (Lauraceae).

Cinnamomum pauciflorum is a valuable aromatic tree of the genus Cinnamomum Trew in the family Lauraceae. To better determine its phylogenetic location with other Cinnamomum species, the complete chloroplast (cp) genome of C. pauciflorum was sequenced. The total cp genome size is 152,766 bp, consisting of a pair of inverted repeats (IRa/b) with a length of 20,074 bp separated by a large single-copy region (LSC) and a small single-copy region (SSC) which are 93,693 and 18,925 bp, respectively. The overall GC content of the cp genome is 39.14%. Maximum-likelihood analysis showed that C. pauciflorum has phylogenetic affinities with Cinnamomum osmophloeum , Cinnamomum aromaticum , Cinnamomum mollifolium , and Cinnamomum tenuipile , providing new insight into the evolution of Lauraceae.
