Resolving phylogenetic conflicts in Pandanales: the dual roles of gene flow and whole-genome duplication.

ABSTRACT:

Introduction

Accurate phylogenetic reconstruction is crucial for understanding evolutionary relationships and biodiversity. Despite advances in molecular systematics, the relationships within Pandanales-which include Cyclanthaceae, Pandanaceae, Stemonaceae, Triuridaceae, and Velloziaceae-remain unresolved. This study aims to clarify these relationships by analyzing transcriptomic and genomic data from these families.

Methods

We analyzed transcriptomic and genomic data from 20 samples representing all five families of Pandanales. Our approach involved assembling 2,668 single-copy orthologous genes (SCOGs) and conducting phylogenetic analyses using both coalescent- and concatenation-based methods, alongside plastid genome data. Additionally, we employed HyDe for gene flow anal
