Incomplete lineage sorting and introgression among genera and species of Liliaceae tribe Tulipeae: insights from phylogenomics.

ABSTRACT:

Background

Phylogenetic research in Tulipa (Liliaceae), a genus of significant economic and horticultural value, has relied on limited nuclear (mostly nuclear ribosomal internal transcribed spacer, nrITS) and plastid DNA sequences, resulting in low-resolution phylogenetic trees and uncertain intrageneric classifications. The genus, noted for its large genome, presents discordant relationships among Amana, Erythronium, and Tulipa, likely due to incomplete lineage sorting (ILS) and/or reticulate evolution. Thus, phylogenomic approaches are needed to clarify these relationships and the conflicting signals within the tribe Tulipeae.

Results

We newly sequenced 50 transcriptomes of 46 species of tribe Tulipeae (including multiple accessions of all four genera) and one outgroup spe
