The complete chloroplast genome of Lagerstroemia intermedia (Lythraceae), a threatened species endemic to southwestern Yunnan province, China

Lagerstroemia intermedia: is a threatened species endemic to southwestern Yunnan province, China. It has high-value light purple-blue petals. Not much is known about the ecological and genetic characteristics of the species. Chloroplast genome sequencing is an efficient tool for understanding enigmatic and basal phylogenetic relationships at different taxonomic levels. Here, we report the chloroplast genome of L. intermedia. The L. intermedia chloroplast genome is 152,330 bp long, with 129 coding genes, including 84 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. Among the 129 genes, 6 coding genes (ndhB, rpl2, rpl23, rps7, rps12, and ycf2), 7 tRNA genes (trnA-UGC, trnI-CAU, trnI-GAU, trnL-CAA, trnN-GUU, trnR-ACG, and trnV-GAC) and 4 rRNA genes (rrn4.5, rrn5, rrn16, and rrn23) occur in the two IR regions. A neighbour-joining (NJ) phylogenetic tree was constructed to show the relationships between species in Myrtales. This complete chloroplast genome of L. intermedia will supply more genetic information about the Lagerstroemia chloroplast and will be useful for further research and conservation of this endemic endangered plant.
