Abstract

Vitex negundo var. heterophylla (Franch.) Rehder is a common small shrub in northern China. In order to study the fine nectar characteristics and water and soil conservation characteristics of V. negundo, the analysis of chloroplast genome would provide theoretical basis for economic development and germplasm utilization of V. negundo. The chloroplast genome sequence (accession number MW366787) of V. negundo was accepted by high-throughput sequencing technology using a plant from Jiulongshan, Mentougou District, Beijing, China. The total length of the chloroplast genome is 154,438 bp, and the A, T, C and G content of the whole genome is 30.48, 31.26, 19.42, and 18.84%, respectively. The phylogenetic analysis of 16 Verbenaceae plants (including V. negundo) with Arabidopsis thaliana as the outgroup was carried out by the maximum likelihood method; and the result shows that V. negundo is relatively closed to Vitex rotundifolia.
