摘要： Ampelopsis delavayana Planchon. ex Franch 1886 is a plant with significant pharmacological effects and ornamental importance. This research unveiled the complete chloroplast (cp) genome sequence of A. delavayana. The study highlights that the cp genome of A. delavayana possesses a distinct tetrameric structure spanning 162,497 base pairs, comprising a small single-copy (SSC) region of 18,902 base pairs, a large single-copy (LSC) region of 90,441 base pairs, and two inverted-repeat regions (IRs), each 26,577 base pairs in length. The GC content of the SSC, LSC, and IR regions of the genome was 31.80%, 35.16%, and 42.82%, respectively, culminating in an overall GC content of 37.27%. The genome comprised 130 genes, which included eight rRNAs, 36 tRNAs, and 86 protein-coding genes. Through phylogenetic analysis utilizing the maximum-likelihood method, it was established that A. delavayana was closely related to Ampelopsis glandulosa var. brevipedunculata, positioning it as a sister species. This report not only provides a scientific reference for understanding the phylogeny of the family Vitaceae but also enriches our genetic information of Ampelopsis.
