Comparison and Phylogenetic Analyses of Nine Complete Chloroplast Genomes of Zingibereae

Zingibereae is a large tribe in the family Zingiberaceae, which contains plants with important medicinal, edible, and ornamental values. Although tribes of Zingiberaceae are well circumscribed, circumscription many genera within relationships among them remain elusive, especially for Boesenbergia, Curcuma, Kaempferia Pyrgophyllum. In this study, we investigated plastome variation nine species representing five Zingibereae. All plastomes showed typical quadripartite structure lengths ranging from 162,042 bp to 163,539 contained 132–134 genes, consisting 86–88 coding 38 transfer RNA genes eight ribosomal genes. Moreover, characteristics long repeats sequences simple sequence (SSRs) were detected. addition, conducted phylogenomic analyses related taxa data additional 32 Genbank. Our results confirmed that Stahlianthus closely supporting idea merging it into Curcuma. Kaempferia, Boesenbergia Zingiber as close relatives grouped together group. Pyrgophyllum not allied Curcuma clade but instead embedded Hedychium clade. demonstrate power plastid phylogenomics improving phylogenetic provide new insight evolution Zingibereceae.
