Journal ArticleDOI
Utilization of wild sunflower species for the improvement of cultivated sunflower
TL;DR: The wild species continue to serve as a source of cytoplasmic male sterility for cultivated sunflower and the recent discovery of genes for high tolerance to the disease Phomopsis/Diaporthe helianthi Munt is an excellent example.
Journal ArticleDOI
Utilization of Sunflower Crop Wild Relatives for Cultivated Sunflower Improvement
TL;DR: The current USDA–ARS National Plant Germplasm System (NPGS) crop wild relatives sunflower collection is the largest extant collection in the world, containing 2519 accessions comprising 53 species—39 perennial and 14 annual.
Journal ArticleDOI
Behavioral and growth responses of specialist herbivore,Homoeosoma electellum, to major terpenoid of its host,Helianthus SPP.
TL;DR: The responses of a sunflower specialist,Homoeosoma electellum, the sunflower moth, to the terpenoids produced by its host plant, Helianthus, were measured, demonstrating that the willingness of larvae to eat tissues contaminated with trichome contents increased with age.
Journal ArticleDOI
Helianthus annuus pollen, an oviposition stimulant for the sunflower moth, Homoeosoma electellum
TL;DR: Females of the sunflower moth, Homoeosoma electellum, laid a total of 242.3 ± 27.4 eggs when provided oviposition sites of wax paper dusted with pollen from cultivated sunflowers, with an evident peak occurring shortly after the onset of the scotophase.
Journal ArticleDOI
Trichome differentiation on leaf primordia of Helianthus annuus (Asteraceae): morphology, gene expression and metabolite profile.
TL;DR: The study has shown that sunflower leaf primordia can serve as a fast and easy to handle model system for the investigation of trichome development in Asteraceae.
