Characterization and phylogenetic analysis of the complete chloroplast genome of Cercis canadensis ‘Forest Pansy’

摘要

Cercis canadensis ‘Forest Pansy’ is a tree species with high ornamental value, which complete chloroplast (cp) genome was sequenced, assembled, and annotated. The genome size is 158,960?bp with a total GC content of 36.17%. The cp genome is made up of a large single-copy region (88,114?bp), a small single-copy region (19,590?bp), and two inverted repeat regions (25,628?bp each). It contains 128 genes, including 84 protein-coding genes, 36 tRNA genes, and 8 rRNA genes. Eighteen genes were duplicated in IRs. The maximum-likelihood (ML) phylogenetic analysis indicated that the Leguminosae species are grouped together, and C. canadensis ‘Forest Pansy’ is closely related to C. canadensis . The result would provide valuable information for genetic studies on Cercis genus .
