BAPTA specifically impairs phot1-mediated growth inhibition. The magnitude of blue-light-induced, phot1-mediated growth inhibition was assessed in the presence of different concentrations of BAPTA. The results are presented as “percent of normal inhibition,” which represents the magnitude of inhibition in BAPTA-treated seedlings relative to the inhibition measured in control (no BAPTA) seedlings 15 min after a 50 μmol m-2 blue-light pulse. At least eight seedlings were measured for each BAPTA concentration. Error bars represent se.
