摘要：
We examined the excitation energy transfer and electron transfer processes in Arabidopsis thaliana thylakoid membranes following replacement of chlorophyll (Ch1) molecules by expression of the vinyl reductase: monovinyl (MV)-Ch1 was replaced with divinyl (DV)-Ch1 and the DV-Ch1 a/DV-Ch1 b ratio was higher than that of control cells. By this replacement, energy transfer within the photosystem (PS) II became faster, whereas the PS II-to-PS I energy transfer was slower. In the DV-Ch1 mutant system, the delayed fluorescence from PS II was not resolved. Alternations of the antenna system and the reaction center are discussed in relation to Ch1 replacement.
