The complete chloroplast genome of Tabebuia rosea (Bignoniaceae)

Tabebuia rosea is a world-renowned woody plant with colorful flowers in full bloom. In addition to its high ornamental value, it also has ecological and medicinal value. In this study, the complete circular chloroplast genome of T. rosea was reconstructed and annotated using Illumina sequencing. The chloroplast genome was 158,919 bp in size with GC content of 38.21%, including a large single-copy region of 85,823 bp, a small single-copy region of 12,816 bp, and a pair of inverted repeats of 30,140 bp. It encoded 132 genes, including 87 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. Based on current available chloroplast genome sequences, the phylogenetic analysis indicated that T. rosea was clustered with T. nodosa and H. chrysanthus. This study provided insights into the evolutionary relationships among different species of Bignoniaceae.
