Changes in photorespiratory CO2 release per Rubisco oxygenation. The PIB (A), the photorespiratory release of CO2 (B), the PIB relative to the rate of vo (C), and the photorespiratory release of CO2 relative to vo (D) at different O2 partial pressures in wild-type (black symbols) and pmdh1pmdh2 (white symbols) plants. Data are means of measurements of three to five different plants, and error bars represent se.
