摘要：Catalpa ovata G. Don is a precious Catalpa tree known as a source of valuable timber and compounds for medicinal usage. In this study, we reported its complete chloroplast genome assembled from Illumina pair-end sequencing data. The completed plastome was 158,355 bp in length, including a large single copy (LSC) region of 85,007 bp, a small single copy (SSC) region of 12,676 bp, and a pair of inverted repeat (IR) regions of 30,336 bp. The overall GC content of the genome was 38.07%, and the corresponding values of the LSC, SSC and IR regions were 36.42%, 33.54%, and 41.33%, respectively. A total of 129 genes were annotated, including 83 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. Phylogenetic analysis strongly supported that Tecomaria capensis was the most closely related species to C. ovata. The newly characterized complete chloroplast genome of C. ovata will provide essential data for further investigation of this precious species.
