Effects of reduced carbonic anhydrase activity on CO₂ assimilation rates in Setaria viridis: a transgenic analysis
In C₄ species, the major β-carbonic anhydrase (β-CA) localized in the mesophyll cytosol catalyses the hydration of CO₂ to HCO₃-, which phosphoenolpyruvate carboxylase uses in the first step of C₄ photosynthesis. To address the role of CA in C₄ photosynthesis, we generated transgenic Setaria viridis depleted in β-CA. Independent lines were identified with as little as 13% of wild-type CA. No photosynthetic defect was observed in the transformed lines at ambient CO₂ partial pressure (pCO₂). At...[Show more]
