Characterization of the complete chloroplast genome of toad lily Tricyrtis Macropoda (Liliaceae)

Abstract

Tricyrtis (Liliaceae) is an endemic genus in East Asia. Many of the species in the genus are in Endangered condition due to habitat loss and extensive horticultural usage in recent decades. In present study, we reported the first Tricyrtis chloroplast (cp) genome, Tricyrtis macropoda, based on Illumina pair-end sequencing data. The complete chloroplast genome size is 155,778 bp. In total, 131 genes were identified, including 85 protein-coding genes, 8 rRNA genes, and 38 tRNA genes. Fifteen genes are containing introns (clpP and ycf3 contained two introns) and 14 genes had two copies. The overall GC content of this genome was 37.4%. A further phylogenomic analysis of Liliales, including 62 taxa, was conducted for the placement of genus Tricyrtis. The complete plastome of T. marcropoda will provide a valuable resource for further genetic conservation, phylogenomic, and evolution studies in the genus and family.
