Title:GeneticCharacteristicsandMolecularMarkersforWheatResistantStarch
Abstract:
Wheatisoneofthemostwidelycultivatedcerealcropsworldwide,providingastaplefoodsourceforasignificantportionoftheworld'spopulation.Starchisthedominantcomponentofwheatgrains,contributingtoitsnutritionalandfunctionalproperties.However,excessivestarchconsumptioncanleadtovarioushealthissues,particularlyrelatedtobloodglucoselevels.Therefore,thedevelopmentofwheatvarietieswithincreasedlevelsofresistantstarch,whichisnotreadilydigestedbyhumanenzymes,hasgainedsignificantattention.Inthispaper,wediscussthegeneticcharacteristicsandmolecularmarkersassociatedwithwheatresistantstarch.
