Natural variation explains why individuals belonging to the same species have different phenotypes. Looking carefully at the genomic sequences of two people, for instance, one can detect a huge number of alleles that make each of us different from our close relatives. This means that we all have eyes, hair, hands but our eyes, hair and hands are unique pieces, something like variations on a theme.
Moving to plants, men combined and fixed by breeding those positive alleles that could have improved plants performance; in most of the cases, breeders created varieties through the combination of selected traits. Having the possibility to dig into the genetic diversity of many varieties we’ll be able to molecularly explore the causes of the phenotypic diversity. ExpoSEED is fully aware that natural variation represents an invaluable resource to highlight new correlations between genotypes and phenotypes. Our project is focused on the exploitation of the genetic variability existing within key factors that control the formation of reproductive meristems and seed differentiation.
