Integrative physicochemical and metabolic profiling of grain components related to nutritional quality in Yunnan hulled wheat and common wheat.

Background: Yunnan hulled wheat (YHW) is a semi-primitive wheat. It retains many nutrients lost in modern common wheat (CW) and has received increasing attention because it is proposed to have higher nutritional values than CW. However, information on the chemical composition and metabolic profiles of nutrient components in YHW and CW is limited.
