Fecundity, phenology, and seed dormancy of F1 wild-crop hybrids in Sunflower (Helianthus annuus, Asteraceae).
TL;DR: It is suggested that F1 wild-crop hybrids had lower fitness than wild genotypes, especially when grown under favorable conditions, but the F1 barrier to the introgression of crop genes is quite permeable.

TL;DR: In this paper, the authors combined ecogeographic and phylogenetic data to predict species distributions, range overlap and niche occupancy in 36 taxa closely related to sunflower (Helianthus annuus L.).
Molecular mapping of the Pl(16) downy mildew resistance gene from HA-R4 to facilitate marker-assisted selection in sunflower.
TL;DR: This is the first report to provide two tightly linked markers for both the Pl16 and Pl13 genes, which will facilitate marker-assisted selection in sunflower resistance breeding, and provide a basis for the cloning of these genes.

Analysis of the relationships of environmental factors with seed oil and fatty acid concentrations of wild annual sunflower
TL;DR: Environmental factors, specifically temperature (maximum and minimum), total solar radiation and daylength for their direct and indirect effects on seed oil and fatty acid concentrations in seed oil of wild annual and cultivated sunflower are examined using correlation and path-coefficient analyses.

TL;DR: It is suggested that a subset of cultivar traits/alleles are advantageous in natural environments but that herbivory may mitigate the selective advantage of some cultivar alleles.
