Abstract
In this study, we reported and characterized the complete chloroplast genome sequence of Catalpa fargesii Bur. f. duclouxii (Dode) Gilmour. The chloroplast genome was determined to be 158,250 bp in length. It contained large single-copy (LSC) and small single-copy (SSC) regions of 84,929 bp and 12,663 bp, respectively, which were separated by a pair of 30,329 bp inverted repeat (IR) regions. The genome is predicted to contain 121 genes, including 78 protein-coding genes, 35 tRNA genes, and 8 rRNA genes. The overall GC content of the genome is 38.1%. A phylogenetic tree reconstructed by 12 chloroplast genomes reveals that C. fargesii is mostly related to Catalpa. ovata and Catalpa. speciosa. This study identified the unique characteristics of the C. fargesii cp genome, which will provide a theoretical basis for species identification and biological research.
