The complete chloroplast genome of <i>Calystegia pubescens</i> ‘Anestia’ Hara 1957 (Convolvulaceae), an endemic species in Asia

In this study, we conducted a comprehensive sequencing and characterization of the chloroplast genome of the Asian endemic species <i>Calystegia pubescens</i> 'Anestia'. The complete genome is 152,079 bp long, with a GC content of 37.37%. It consists of a large single-copy region (87,891 bp), a small single-copy region (19,888 bp), and a pair of inverted repeats regions (22,149 bp). A total of 126 genes were identified, including 81 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenetic analysis revealed a close relationship between <i>C. pubescens</i> 'Anestia' and <i>C. hederacea</i>. These results provide valuable genetic insights for species identification and phylogenetic studies within the genus <i>Calystegia</i>.
