The complete plastid genome of an evergreen tree Litsea elongata (Lauraceae: Laureae).

Litsea elongata (Nees) J. D. Hooker is an economically important timber and medicine tree. In this study, the complete plastid genome of L. elongata was assembled and analyzed. The plastid genome mapped a 154,027 bp circular DNA molecule with a GC content of 39.2%, consisting of a large single-copy region (LSC) of 93,688 bp, a small single-copy region (SSC) of 18,851 bp, and two inverted repeat regions (IRa and Irb) of 20,744 bp. A total of 127 genes were detected in the plastid genome, including eight ribosomal RNA (rRNA) genes, 36 transfer RNA (tRNA) genes, and 83 protein-coding genes. Phylogenomic analysis based on 39 complete plastomes of Laureae in the family Lauraceae supports the close relationships among L. coreana, L. elongata, L. japonica, and L. pierrei.
