Abstract
Physochlaina is an important perennial herbaceous genus with significant medicinal value, while the phylogeny of Physochlaina and tribe Hyoscyameae is not well resolved yet. In this study, we report the complete chloroplast genome sequences of Ph. physaloides, its complete chloroplast genome is 156,413 bp in length, which is a typical quadripartite structure that includes a large single-copy region of 86,659 bp, a small single-copy region of 18,012 bp, and its GC content was 37.7%. A total of 132 genes were identified, including 87 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. Furthermore, a phylogenetic tree of the tribe Hyoscyameae was constructed based the complete chloroplast genome sequence, and a new topology of the tribe was obtained. This study provides valuable genetic information for the conservation and utilization of Ph. physaloides and also provide the potential for better understanding of the phylogeny of Hyoscyameae and Solanaceae.
