Characterization of the complete chloroplast genome of Toddalia asiatica (L.) Lam.

Toddalia asiatica (L.) Lam. belongs to family Rutaceae and mainly distributes in dry areas of bushes in tropical Africa, Asia, and Swaziland. Sometimes it can be used as fodder for goats, but it has been used as herbs in traditional medical treatment for 1000 years. In this study, we sequenced the sample of T. asiatica and determined its complete chloroplast genome. The length of CP genome is 158,434 bp, includes two invert repeats (IR) regions of 27,008 bp, a large single-copy (LSC) region of 86,132 bp, and a short single-copy (SSC) region of 18,286 bp. There are 133 genes, which includes 88 protein-coding genes, 8 rRNA and 37 tRNA, and 38.5% overall GC content. Each of trnK-UUU, rps16, trnG-UCC, atpF, rpoC1, trnL-UAA, trnV-UAC, petB, petD, rpl16, rpl2, ndhB, trnI-GAU, trnA-UGC, and ndhA genes contains a intron, clpP and ycf3 contains 2 intron. The phylogenetic analysis result shows that T. asiatica has the closest relationship with Zanthoxylum armatum (MT990984) and Zanthoxylum nitidum (MN508801).
