Progress of Research on Photosynthetic Acclimation of Plant to Elevated Atmospheric CO_(2)

With the rapid increasing in atmospheric CO_(2) concentration,people have a deep study in photosynthetic response to high CO_(2) concentrations,the reasons in photosynthetic acclimation to high CO_(2) concentrations might include that: the feedback restrain to photosynthesis caused by deposit of carbohydrate and redox signals arising from the plastoquinone pool and from the accumulation of hydrogen peroxide;decrease of rubisco content and activity was induced by levels of rubisco subunit mRNA;changes in stomata states.In addition,the levels of photosynthesis gene expression induced by C/N balance,plant growth regulators and hexoses might also result in photosynthetic acclimation.
