Differential recovery of the phosphorylation level of Lhcb1 and Lhcb2 in multiple mutants. (A) The level of phosphorylation of the LHCII antenna and the core protein PsbA/D1 of PSII was assessed by immunoblotting with antibodies specifically recognizing the phosphorylated peptides. As a control, the total accumulation of the protein was also assessed by immunoblotting. (B) The phosphorylation level of Lhcb1 and Lhcb2 in 15 day-old plantlets was measured by quantification of the immunoblot signal after separation by Phos-tag PAGE. The average level of phosphorylation under 100 µmol photons m⁻² s⁻¹ is reported with its standard deviation (n = 3). The phosphorylation levels in the mutants is different from the WT, p values of a Welch T-test of the difference between the double (stn7/STN8/pph1/PBCP) and the triple (stn7/STN8/pph1/pbcp) mutants are shown.
