Plastome phylogenomics of Cephalotaxus (Cephalotaxaceae) and allied genera.

ABSTRACT:

Background and aims

Cephalotaxus is a paleo-endemic genus in East Asia that consists of about 7-9 conifer species. Despite its great economic and ecological importance, the relationships between Cephalotaxus and related genera, as well as the interspecific relationships within Cephalotaxus, have long been controversial, resulting in contrasting taxonomic proposals in delimitation of Cephalotaxaceae and Taxaceae. Based on plastome data, this study aims to reconstruct a robust phylogeny to infer the systematic placement and the evolutionary history of Cephalotaxus.

Methods

A total of 11 plastomes, representing all species currently recognized in Cephalotaxus and two Torreya species, were sequenced and assembled. Combining these with previously published plastomes, we reconstru
