Phylogenomics reveals the evolution of floral traits associated with pollinators and pollinator-prey conflict within the carnivorous Pinguicula subgenus Temnoceras.

ABSTRACT:

Premise

The carnivorous plant genus Pinguicula (Lentibulariaceae) exhibits remarkable floral diversity associated with pollination, particularly in the largest subgenus Temnoceras, which spans Mexico and Central America. Despite this diversity, the relationships between species and the evolution of key floral traits remain unresolved. Here, we employed whole-genome sequencing to reconstruct a robust phylogeny and examine the evolution of pollination syndromes and potential pollinator-prey conflicts.

Methods

We generated nuclear and plastid genomic data for 32 Pinguicula species. Phylogenetic relationships were inferred using 2189 BUSCO loci analyzed through ASTRAL. Morphological traits associated with pollination and carnivory were assessed with ancestral state reconstructio
