Increased lysine content in rice grains by over-accumulation of BiP in the endosperm.
(58/197)
Over-accumulation of lysine-rich binding protein (BiP) in the rice endosperm caused strong endoplasmic reticulum (ER) stress and reduced seed storage proteins, resulting in a relative increase in nutritionally balanced non-seed storage proteins. We show that transgenic rice with over-accumulated BiP was a high-lysine rice germplasm and that the over-accumulation of BiP in the endosperm offered a unique strategy to improve the lysine content of cereal grains.
