Figure 7.
COR-induced perturbation of photosynthetic efficiency is dependent on COI1. coi1-30 plants were treated with COR or a mock control and imaged for chlorophyll fluorescence as described in the legend to Figure 5. A, Representative false-color images of ΦII at selected times after dawn (dark-light transition) of day 2 (1 d after treatment). B, ΦII values calculated from chlorophyll fluorescence images denote means ± se of three independent replicates. For each replicate, ΦII was quantified for two to three actively growing leaves per plant.
