pollinators facilitate interspecific crosses with sunflower , H. annuus var. macrocarpus. To estimate the occurrence of crop-to- wild and wild -to-crop gene flow , off-type plants in progenies of pure stands ...
of hybridization and gene flow involving domesticated and wild sunflowers in Argentina. To address the risks of introgression of variants from the cultivated sunflower into invasive wild Helianthus , we used ...
morphological and nutritional characters were measured in a segregating population of sunflower crop‐ wild hybrids and wild and cultivated lines. Seed predation rates among lines were then assessed in the field ...
Abstract Wild Helianthus species are a valuable genetic resource for the improvement of cultivated sunflower . We report the discovery and characterization of a unique high frequency production ...
preventive and control strategies. Wild sunflower ( Helianthus annuus L.) is native to North America and was introduced, and has become invasive, in several countries, including Argentina (ARG). Here, using ...
in ruderal ( wild Helianthus annuus ) and agrestal (natural crop– wild hybrid) habitats of Argentina as well as volunteer populations (progeny of commercial cultivars). Methods In a seed-bank experiment, we ...
sweeps. Zhou et al. 2015 Sunflower 122 genes 15 genes Transcriptome data from 38 genotypes of wild and cultivated (landrace and modern lines) Helianthus annuus (L.), 21 genotypes of Helianthus petiolaris ...
of Helianthus annuus ( sunflower ) full-length gypsy and copia elements, we explore the contribution of these sequences to genome size variation among eight diploid Helianthus species and an outgroup taxon ...
(Gillies et al. 2002). Moreover, cultivated sunflower (also H. annuus ) has lost the highly branched architecture that is characteristic of its wild progenitor, thereby raising questions about the possible ...
Chapman MA, Pashley CH, Wenzler J, Hvala J, Tang S, Knapp SJ, Burke JM. A genomic scan for selection reveals candidates for genes involved in the evolution of cultivated sunflower ( Helianthus annuus ...
