The complete chloroplast genome sequence of the endangered species: Ephedra rhytidosperma (Ephedraceae): insights into genome features and evolutionary relationships

Year: 2025

Type: article

Abstract: Ephedra rhytidosperma belongs to the genus Ephedra (Ephedraceae) and plays a significant role in desertification control. In this study, we assembled the complete chloroplast genome of E. rhytidosperma for the first time, revealing a typical quadripartite structure. The chloroplast genome was 109,545 base pair (bp) long with a GC content of 36.8%, encoding 118 complete genes. Phylogenetic reconstruction resolved E. rhytidosperma, E. minuta, E. likiangensis, E. equisetina, Ephedra gerardiana, E. fedtschenkoae, and E. monosperma formed a monophyletic group, indicating their close relationship. The chloroplast genome of E. rhytidosperma establishes a good foundation for further genetic and genomic studies of the Ephedra.
