Chlorophyll fluorescence measurements for mutants affected by growth in nonphotorespiratory conditions.

Controls are described further in text. Fv/Fm, +, measurement indicating reduced Fv/Fm, −, measurement indicating no difference compared to wild type Col. NPQ, +, measurement indicating increased NPQ, −, measurement indicating no difference compared to wild type Col. BHL, before high light treatment, AHL, after high light treatment, Recovery, after 2 days return to original growth conditions. ND, direct air vs. high CO2 comparisons were not done for these mutant controls.
