Numerous chemical compositions and putative phylogenetic affiliations of this species have been documented in prior research. Nevertheless, there is a scarcity of accessible publications regarding the genomic data of L. rotata, particularly its chloroplast genome. This dearth of knowledge hampers the comprehensive investigation of its phylogenetic placement within the Labiatae family. In this study, we present a comprehensive analysis of the plastid genome of L. rotata. The plastid genome has a length of 151,837 base pairs (bp) and a GC content of 38.5%. Within this genome, a total of 135 genes were identified, including 90 protein-coding genes, 37 transfer RNA (tRNA) genes, and eight ribosomal RNA (rRNA) genes. By employing phylogenetic analysis, the taxonomic position of L. rotata within the family Labiatae is elucidated, highlighting a close relationship between the genus Lamiophlomis and the genus Phlomis. Notably, extensive genetic variations were uncovered between L. rotata and other Phlomis species. This study could provide significant insights for understanding the phylogenetic relationships of taxa within Labiatae. 收起
