Achieving high yield and good quality in crops is essential for human food security and health.However,there is usually disharmony between yield and quality.Seed storage protein(SSP)and starch,the predominant components in cereal grains,determine yield and quality,and their cou-pled synthesis causes a yield-quality trade-off.Therefore,dissection of the underlying regulatory mechanism facilitates simultaneous improvement of yield and quality.Here,we summarize current findings about the synergistic molecular machinery underpinning SSP and starch synthesis in the leading staple cereal crops,including maize,rice and wheat.We further evaluate the functional conservation and differentiation of key regulators and specify feasible research approaches to iden-tify additional regulators and expand insights.We also present major strategies to leverage re-sultant information for simultaneous improvement of yield and quality by molecular breeding.Finally,future perspectives on major challenges are pro-posed.
