Comparative chloroplast genomics provides insights into the phylogenetic relationships and evolutionary history for Actinidia species.

ABSTRACT: Actinidia species are fruit trees with various functions, such as providing edible fruit, serving as ornamental plants, and having medicinal benefits. However, the taxonomy of Actinidia species is controversial due to widespread hybridization, the history of divergence and polyploid speciation among Actinidia species also remains unclear. In this study, we conducted comparative analyses of the chloroplast genomes and ploidy among multiple Actinidia species. The genes clpP, infA, ndhD, ndhK, and rpl20 were absent from these chloroplast genomes. The ycf2 and rpl20 genes in the Actinidia species were under positive selection. Several regions (rps16-trnQ-UUG, trnS-GCU-trnR-UCU, ndhC-trnV-UAC, rbcL-accD, rps12-psbB, trnN-GUU-ndhF, ycf1-trnN-GUU, and trnH-GUG-psbA) and genes (ycf1, ycf2, accD, r
