Chloroplast genome of plantago major, a medicinal plant in China

Plantago major (Plantaginaceae) is a medicinal plant in Chinese folk culture, known for its famous medicinal components such as plantagomain. In this study, we conducted genome sequencing of P. major using Illumina sequencing technology. The assembled complete chloroplast genome had a length of 165,044 bp, comprising a large single-copy regions (82,963 bp), a small single-copy regions (4,633 bp), and a pair of inverted repeat regions (38,724 bp). A total of 140 genes were detected, including 94 CDS, 38 tRNA, and 8 rRNA. Phylogenetic analysis revealed a close genetic relationship between P. major and P. rigida. These findings provide valuable data for a comprehensive understanding of the biological characteristics of P. major.
