Comparative analysis of Diospyros (Ebenaceae) plastomes: Insights into genomic features, mutational hotspots, and adaptive evolution.

ABSTRACT: Diospyros (Ebenaceae) is a widely distributed genus of trees and shrubs from pantropical to temperate regions, with numerous species valued for their fruits (persimmons), timber, and medicinal values. However, information regarding their plastomes and chloroplast evolution is scarce. The present study performed comparative genomic and evolutionary analyses on plastomes of 45 accepted Diospyros species, including three newly sequenced ones. Our study showed a highly conserved genomic structure across the Diospyros species, with 135-136 encoding genes, including 89 protein-coding genes, 1-2 pseudogenes (Ψycf1 for all, Ψrps19 for a few), 37 tRNA genes and 8 rRNA genes. Comparative analysis of Diospyros identified three intergenic regions (ccsA-ndhD
