Genomic analysis reveals the complete 153,168 bp chloroplast sequence of Echinops davuricus, supporting monophyly in Cardueae and enhancing medicinal plant phylogenetics.
Echinops davuricus Trevir. (Asteraceae) is a perennial medicinal herb. In this study, we sequenced and assembled its complete chloroplast genome. The plastome spans 153,168 bp with an overall GC content of 37.76%, showing a typical quadripartite structure. It encodes 131 genes in total, including 87 protein-coding genes (PCGs), 36 transfer RNA (tRNA) genes and eight ribosomal RNA (rRNA) genes. Phylogenetic analysis based on whole plastomes strongly supports the monophyly of both Echinops and Cardueae. This work enriches genomic resources for Echinops and provides a valuable basis for its phylogenetic and evolutionary studies.
