摘要：

Light-harvesting complex 11 (LHCII, the major plant light-harvesting pigment-protein complex, efficiently harvests light-energy. However, if the incident light intensity is too high and photosynthesis becomes saturated, LHCII can switch into a quenching state that prevents photodamage. This important process is called non-photochemical quenching, or NPQ, and represents feedback control. Andrew Pascal et al. have recently proposed a detailed model of NPQ based upon the crystal structure of LHCII from spinach.
