Plastid genome data provide new insights into the phylogeny and evolution of the genus Epimedium.

ABSTRACT:

Introduction

Epimedium L., the largest herbaceous genus of Berberidaceae, is one of the most taxonomically difficult representatives. The classification and phylogenetic relationships within Epimedium are controversial and unresolved.

Objectives

For the first time, we systematically studied the phylogeny and evolution of Epimedium based on plastid genome (plastome) data for better understanding this enigmatic genus.

Methods

We explored the molecular phylogeny, assessed the infrageneric classification, estimated the divergence times, and inferred the ancestral states for flower traits of Epimedium based on 45 plastomes from 32 species.

Results

The Epimedium plastome length ranged from 156,635 bp to 159,956 bp. Four types of pla
