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 shows a single nucleotide polymorphism in a cell-wall invertase gene affects sunflower nectar chemistry, microbial diversity, and pollinator visits.

The study identifies pavettamine, a toxin causing gousiekte in livestock, as being synthesized by bacterial endophytes via a conserved gene cluster acquired through horizontal gene transfer.

This study shows that the specificity of a vertically-transmitted plant-bacterium symbiosis is maintained through microbe-microbe interactions and transmission barriers.
