Chloroplast genome and haplotype relationships unravel the genetic introgression and complex evolutionary history of East Asian Rosa section Synstylae roses (Rosaceae).

ABSTRACT:

Background

The section Synstylae of the genus Rosa (Rosaceae) is predominantly distributed across the Eastern Asiatic Floristic Region and is characterized by increased species diversity and natural hybrids. These characteristics render species within this section exemplary for studying phenotypic variability and easy crossbreeding, which hold potential for advancements in the rose-breeding industry. However, genetic introgression and hybridization have posed challenges to our understanding of their phylogenetic relationships. Despite recurrent interspecific introgression, chloroplast DNA can still aid in phylogenetic inference within the section Synstylae due to its uniparental inheritance and high conservation.
