The complete chloroplast genome sequence of Oroxylum indicum (L.) Kurz (Bignoniaceae) and its phylogenetic analysis

Oroxylum indicum (L.) Kurz is a medicinal plant commonly used in the southwest of China. In this study, we sequenced the complete chloroplast (cp) genome sequence of O. indicum to investigate its phylogenetic relationship in Bignoniaceae. The cp genome of O. indicum is 162,123 bp in length with 37.8% overall GC content, including a large single-copy (LSC) region of 86,416 bp and a small single-copy (SSC) region of 12,811 bp, which are separated by a pair of inverted repeats (IRs) of 31,448 bp. The cp genome contains 132 genes, including 87 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. Phylogenetic analysis showed that O. indicum clustered together with Tr. Bignonieae Dumort.
