The paper shows that pollinator guilds shape sunflower nectar microbiota in a genotype-dependent manner, with diurnal visits seeding specialist taxa that depend on nectar availability and composition.

The paper examines metabolic diversity in Arabidopsis thaliana using metabolomics and GWA mapping, finding that local adaptation and selection shape secondary metabolite profiles through haplotype variation.

This study uses cybrids to show that plasmotype variation affects plant phenotypes through additive and epistatic interactions, with epistasis explaining more variance than additivity.
