The complete chloroplast genome sequence of Catalpa bungei (Bignoniaceae): a high-quality timber species from China

Abstract

Catalpa bungei is an important resource of timber, belonging to the genus catalpa (Bignoniaceae). In this study, we sequenced complete chloroplast (cp) genome of C. bungei, using a NovaSeq 6000 sequencing platform. The genome of the C. bungei was 152,153 bp in length, including a large single-copy region (84,910 bp), a small single-copy region (12,664 bp), and two inverted repeats regions (30,285 bp). It encodes 126 genes, including 81 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenetic analyses were performed based on 15 cp genomes using the maximum likelihood (ML) method, supported that C. bungei was probably more closely related to C. speciosa. This study, the cp genome of C. bungei was assembled, which will provide more theoretical basis for determine the phylogenetic relationships of the Catalpa and related species.
