DOIAbstract
• The development of modern crops typically involves both selection and hybridization, but to date most studies have focused on the former. In the present study we explore how both processes, and their interactions, have molded the genome of the cultivated sunflower, a globally important oilseed. • To identify genes targeted by selection during the domestication and improvement of sunflower, and to detect post-domestication hybridization with wild species, we analyzed transcriptome sequences of 80 genotypes, including wild, landrace, and modern lines of Helianthus annuus, as well as two cross-compatible wild relatives, H. argophyllus and H. petiolaris. • Outlier analyses identified 122 and 15 candidate genes associated with domestication...
