Admixture with cultivated sunflower likely facilitated establishment and spread of wild sunflower (H. annuus) in Argentina

The paper investigates the invasion history of wild sunflower in Argentina, finding that admixture with cultivated sunflower and genomic selection contributed to its establishment and spread.

Repeatability of adaptation in sunflowers: genomic regions harbouring inversions also drive adaptation in species lacking an inversion

The paper investigates the repeatability of adaptation in sunflowers, finding that genomic regions with inversions contribute to adaptation even in species without such inversions.

High homozygosity of inversions in sunflower species largely averts accumulation of deleterious mutations

This study examines recombination, transposable elements, and deleterious mutations in sunflower species, finding that inversion homozygosity reduces mutation accumulation.

Genetic basis and dual adaptive role of floral pigmentation in sunflowers

The paper identifies a single MYB transcription factor, HaMYB111, as the genetic basis for UV pigmentation diversity in sunflowers and shows its dual role in pollinator attraction and abiotic stress response.

An unexpected donor in the adaptive introgression candidate Helianthus annuus subsp. texanus.

The paper investigates introgression in Helianthus annuus subsp. texanus using genome and phenotypic data, finding introgression from H. argophyllus rather than H. debilis as previously hypothesized.

Massive haplotypes underlie ecotypic differentiation in sunflowers

The paper identifies large haplotype blocks associated with ecotypic differentiation in sunflowers, showing how structural variation maintains adaptive alleles despite hybridization.
