C monocots and C dicots exhibit rapid photosynthetic induction response in contrast to C plants.

Considering the prevalence of ever-changing conditions in the natural world, investigation of photosynthetic responses in C plants under fluctuating light is needed. Here, we studied the effect of dynamic illumination on photosynthesis in totally 10 C, C-C intermediate, C-like and C dicots and monocots at CO concentrations of 400 and 800 μmol mol. C and C-like plants had faster photosynthetic induction and light-induced stomatal dynamics than C plants at 400 μmol mol, but not at 800 μmol mol CO, at which the CO supply rarely limits photosynthesis.
