Illustration showing the shift in the limiting step of CO2 assimilation. a and b are limitations of leaves under K-deficiency (−K) and sufficient K supply (+K) treatments, while c and d are corresponding traits of siliques. CO2 assimilation rate limited by RuBP carboxylation (A c: red line), RuBP regeneration (A r: blue line), the maximum rate of RuBP carboxylation (V cmax), the maximum rate of electron transport (J max) and the intercellular CO2 concentration at which the transition from Rubisco to RuBP regeneration limitation occurs (C transition) were modeled and calculated using the Farquhar, von Caemmerer and Berry (FVCB) photosynthesis model with R plantecophys package
