| 摘要 | Lindera is a genus (c. 100 spp.) of trees belonging to the "core Laureae" group in the family Lauraceae. It is often confused with Litsea, and the systematics of the genus is unclear. Here, total 10 complete plastomes from nine trinerved Lindera species and another species Lindera obtusiloba (sect. Palminerviae Meissn.) were sequenced. Nine highly variable regions, trnH-GUG/psbA, psbM/trnD-GUC, petA/psbL, ndhF, trnL-UAG/ndhD, and ycf1, were identified among the 10 Lindera species. In addition, a total of 1,836 mutation events including six micro-inversions, 156 indels, and 1,674 substitutions, were also summarized. Comparing our sequences with other available plastomes in the "core Laureae," we put forward that six hypervariable loci, trnH-GUG/psbA, ndhF, ndhF/rpl32, trl32/trnL-UAG, ndhD, and ycf1, could potentially be used as plastid barcode candidates for species identification. Further phylogenetic analyses were conducted using 49 complete Lauraceae plastomes. The results supported a close relationship among trinerved Lindera species and suggested an improved trinerved group comprising species of trinerved Lindera species and Iteadaphne caudate. |
