C4 plants have evolved to minimize the effects of rubisco's inefficiency at high temperatures by fixing carbon twice in two different types of cells - mesophyll cells and bundle sheath cells. This allows the concentration of CO2 to be increased in the bundle sheath cells where rubisco is located, reducing the likelihood of oxygenase reactions and increasing the efficiency of photosynthesis.
