Phylogeny and evolution of Asparagaceae subfamily Nolinoideae: new insights from plastid phylogenomics.

ABSTRACT:

Background and aims

Asparagaceae subfamily Nolinoideae is an economically important plant group, but the deep relationships and evolutionary history of the lineage remain poorly understood. Based on a large data set including 37 newly sequenced samples and publicly available plastomes, this study aims to better resolve the inter-tribal relationships of Nolinoideae, and to rigorously examine the tribe-level monophyly of Convallarieae, Ophiopogoneae and Polygonateae.

Methods

Maximum likelihood (ML) and Bayesian inference (BI) methods were used to infer phylogenetic relationships of Nolinoideae at the genus level and above. The diversification history of Nolinoideae was explored using molecular dating.

Key results

Both ML and BI analyses identically recovered five clades
