| Research Abstract |
We have studied on glutathione-dependent regulation mechanism on the Calvin cycle using Arabidopsis. The results obtained from transgenic plants with increased accumulation of a plastidic aldolase undergoing glutathionylation indicated that FBA activity is a limiting factor for photosynthetic CO_2 assimilation and that it is likely to be regulated by glutathione. We found that glutathione feeding by subirrigation increased N, chlorophyll and Rubisco protein contents, and promoted CO_2 assimilation rate in a manner different from conventional nitrogen fertilizer effects.
