The low chlorophyll b mutant of high yield rice had a lower light-harvesting complex 2 content than the wild type. The stability of oxygen evolution side of photosystem 2 was only slightly lower. A lower photon absorption rate and a stronger xanthophyll cycle capacity of this mutant led to a higher endurance to strong irradiance and a lower photoinhibition as compared with the wild type rice.

Additional key words: chlorophyll fluorescence; irradiance; Oryza sativa; photoinhibition; photosystem 2; pigment-bound proteins; quenching; xanthophyll cycle
