Outline of Final Research Achievements |
Since plants experience a highly variable light environment over the course of the day, plants need a highly responsive regulatory system to keep photosynthetic light reactions in balance with the needs and restrictions of the downstream metabolism. To reveal the molecular mechanisms of their photosynthetic response to fluctuating light, we examined the role of two cyclic electron flows around photosystem I (CEF-PSI); one depending on PGR5 (PROTON GRADIENT REGULATION 5) and PGRL1 (PGR5-LIKE PHOTOSYNTHETIC PHENOTYPE 1) proteins and one on chloroplast NADH dehydrogenase-like (NDH) complex. The present study revealed that both PGR5/PGRL1-dependent and NDH-dependent CEF-PSI have physiological roles in sustaining photosynthesis and growth of rice under fluctuating light.
