摘要：

After a brief exposure to supra-saturating light, leaves of a tobacco transformant, in which chloroplastic NAD(P)H dehydrogenase (NDH) Tvas defective, showed more severe photoinhibition than the wild-type, when judged by the parameter of chlorophyll fluorescence Fv/Fm, Repeated application of supra-saturating light eventually resulted in chlorosis in the NDH-defective mutant, while the mild-type sustained less photodamage and was able to recover from it. The mechanism of the phenomena is discussed with respect to the potential role of NDH in photosynthesis. (C) 1999 Federation of European Biochemical Societies.
