Abstract
is a genus (c. 100 spp.) of trees belonging to the "core Laureae" group in the family Lauraceae. It is often confused with , and the systematics of the genus is unclear. Here, total 10 complete plastomes from nine trinerved species and another species (sect. Meissn.) were sequenced. Nine highly variable regions, -GUG/, /-GUC, /, , -UAG/, and , were identified among the 10 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, -GUG/, , /, UAG, , and , 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 species and suggested an improved trinerved group comprising species of trinerved species and .
