Abstract
Chasmanthium latifolium (Michx.) H.O.Yates is a popular ornamental plant native to southeastern North America. Genomic data and genetic studies related to Chasmanthium latifolium are limited. Therefore, the complete chloroplast genome of Chasmanthium latifolium was sequenced, assembled, and characterized in this study. The complete chloroplast genome was 138,934 bp in length and contained 105 unique genes (77 protein-coding genes, 24 tRNA genes, and 4 rRNA genes). Phylogenetic analyses showed that Chasmanthium latifolium and Chasmanthium laxum clustered into a separate clade with the closest affinity to the clade comprising Zeugites pittieri Hack and Lophatherum gracile Brongn. In conclusion, our study describes the complete chloroplast genome of Chasmanthium latifolium for the first time, contributing to a better understanding of its taxonomy and evolution.
