Abstract excerpt

Photosynthetic induction, characterized by the lag in CO2 assimilation rates during transition from darkness to light, has traditionally been attributed to Rubisco activase activity and stomatal opening. Yet, the faster induction of photosynthesis in the 2-Cys peroxiredoxins (Prxs) mutant (2cpab) suggested a role for oxidative signals in regulating photosynthetic rates, although the underlying molecular mechanism...
