A plant single nucleotide polymorphism impacts nectar sugar composition, microbial diversity and pollinator visits

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

Genomic and eco-geographic features of locally adapted inversions in wild sunflowers

This study identifies locally adaptive chromosomal inversions in wild sunflowers and finds they are more common in sympatric populations and have distinct genomic features.

Fine mapping and genomic analyses reveal a tandem kinase-pseudokinase candidate underlying OrDeb2-mediated resistance to Orobanche cumana in sunflower

This study identifies a tandem kinase-pseudokinase gene, RLK-2, as a candidate underlying OrDeb2-mediated resistance to Orobanche cumana in sunflower through genetic and physical mapping.

The genomics of linkage drag in sunflower

This study analyzes the genomic and phenotypic impacts of wild introgressions in sunflower, finding that while some traits improve, most introgressions negatively affect yield and quality.
