A genomic scan for selection reveals candidates for genes involved in the evolution of cultivated sunflower (Helianthus annuus).
Genomic scans for selection are a useful tool for identifying genes underlying phenotypic transitions. In this article, we describe the results of a genome scan designed to identify candidates for genes targeted by selection during the evolution of cultivated sunflower. This work involved screening 492 loci derived from ESTs on a large panel of wild, primitive (i.e., landrace), and improved sun...
متن کاملMolecular Evolution of Candidate Genes for Crop-Related Traits in Sunflower (Helianthus annuus L.)
Evolutionary analyses aimed at detecting the molecular signature of selection during crop domestication and/or improvement can be used to identify genes or genomic regions of likely agronomic importance. Here, we describe the DNA sequence-based characterization of a pool of candidate genes for crop-related traits in sunflower. These genes, which were identified based on homology to genes of kno...
متن کاملIdentification of Candidate Genes Associated with Leaf Senescence in Cultivated Sunflower (Helianthus annuus L.)
Cultivated sunflower (Helianthus annuus L.), an important source of edible vegetable oil, shows rapid onset of senescence, which limits production by reducing photosynthetic capacity under specific growing conditions. Carbon for grain filling depends strongly on light interception by green leaf area, which diminishes during grain filling due to leaf senescence. Transcription factors (TFs) regul...
متن کاملThe potential for gene flow between cultivated and wild sunflower (Helianthus annuus) in the United States.
The transfer of genes from crop plants to their wild relatives via hybridization has emerged as one of the primary risks associated with the commercialization of genetically engineered crops. Although previous studies have revealed relatively high levels of hybridization when crop plants come into contact with their wild relatives, the frequency of such contact across the range of cultivation o...
متن کاملToward a Molecular Cytogenetic Map for Cultivated Sunflower (Helianthus annuus L.) by Landed BAC/BIBAC Clones
Conventional karyotypes and various genetic linkage maps have been established in sunflower (Helianthus annuus L., 2n = 34). However, the relationship between linkage groups and individual chromosomes of sunflower remains unknown and has considerable relevance for the sunflower research community. Recently, a set of linkage group-specific bacterial /binary bacterial artificial chromosome (BAC/B...
