摘要：
Litsea elongata(Nees) J. D. Hooker is an economically important timber and medicine tree. In this study, the complete plastid genome ofL. elongatawas 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 amongL. coreana,L. elongata,L. japonica, andL. pierrei.
