Comparative analysis of chloroplast genomes reveals molecular evolution and phylogenetic relationships within the Papilionoideae of Fabaceae.

ABSTRACT:

Background

The structure of chloroplast genomes (cpDNAs) in Fabaceae (Fab.) has undergone significant evolutionary modifications. Within the Papilionoideae (Pap.), the emergence of the Inverted Repeat-Lacking Clade (IRLC) represents a major genomic alteration. However, the molecular evolution and phylogenetic relationships within Pap. remain poorly resolved due to limited molecular data and incomplete research, highlighting the need for systematic investigation.

Purpose

This study presents an in-depth analysis of the cpDNAs within the Pap., with the aim of unraveling the molecular evolution and phylogenetic interconnections among its species.

Methods

Complete cpDNAs of 18 Pap. species were sequenced using the Illumina Novaseq 6000 platform, followed by assembly and an
