Recently developed techniques that allow the estimation of the quantum efficiencies of photosystems I and II in vivo (1, 2, 3) have allowed us to adopt a quantitative approach to the analysis of the relationship between both photosystems and carbon assimilation (3, 4, 5). In this report we will describe the key findings of this and other related work which relates to the co-ordination of the quantum efficiencies of both photosystems, and the co-ordination of the thylakoids and the Calvin cycle activity.
