Changes in net CO₂ assimilation rate and photosynthetic performance measurements in mmdh mutants. A, Net CO₂ assimilation rate under growth conditions. B, Stomatal conductance to water vapor under growth conditions. C, Internal CO₂ concentration under growth conditions. D, Maximum photosynthetic electron transport rate (ETC) inferred from A/C_i curves. Bars are means ± sd (n > 3), and letters designate groups that significantly differ (P < 0.05). Wt, Wild type. Plants were grown under short-day conditions.
