Figure 6. The 14-3-3 l Mutation Does Not Affect Blue Light–Activated Chloroplast Movement in Leaves of Wild-Type or Mutant Arabidopsis Plants.
(A) Kinetics of chloroplast accumulation induced by 7 h of 1.0 μmol m2 s1 blue light and subsequent recovery in darkness. WT, wild type.
(B) Kinetics of chloroplast avoidance response induced by 7 h of 45 mmol m2 s1 blue light and subsequent recovery in darkness.
(C) Complex chloroplast response induced by 7 h of 15 mmol m2 s1 blue light and subsequent recovery in darkness. Rapid accumulation is reversed
by a slower but dominating avoidance response.
(D) Steady state chloroplast positions following 7 h of blue light at 15 mmol m2 s1. With or without the phot1-5 mutant background, the 14-3-3 κ
mutation reduces the extent of avoidance by roughly the same amount. Note that in the wild-type background, the result is a slight net accumulation
response. Each data point represents the average of five to seven measurements of separate leaves. Error bars represent SE. Measurements performed
with the method described by de Carbonnel et al. (2010).
