Allelic variation of gliadin-encoding genes in a collection of tetraploid wheat genotypes

摘要: Wheat is one of the main crops bred worldwide. Durum wheat, specifically, a key element Mediterranean diet, representing an elite crop grown in Italy. wheat nutritional and technological values are largely due to grain protein content (GPC), complex genetic trait strongly affected by environmental factors management practices. In last decades, several breeding programs have been focused on improving GPC both traditional innovative approaches. Among seed storage proteins, prolamins, including gliadins glutenins, represent major component. These two classes proteins indeed responsible gluten formation confer extensibility elasticity dough. Besides being crucial importance for properties rheological characteristics, especially gliadins, found be triggers human health, as involved number consumption-related conditions, such celiac disease, non-celiac sensitivity, defined onset variety manifestations related rye barley ingestion, allergies, ingestion or inhalation (of flour pollen). The identification loci gliadin expression, particularly polymorphism aforementioned genes, which could result lower immunogenic/toxic potential, great programs. For this purpose, we screened collection tetraploid genotypes allelic variants annotated genes durum genome, order identify resources available breeders improve properties. Phylogenetic analysis among different species Triticum genus silico expression data may also useful exploitation scenario gliadin–glutenin interaction role adverse reactions consumption.
