Accumulation of protein complexes.
A, Coomassie-stained BN-polyacrylamide gel of wild-type and PPD1 RNAi mutant thylakoid membranes solubilized with dodecyl β-d-maltoside. B, immunodetection of Lhca1, PsaF, and PPD1 from BN-PAGE. PPD1 RNAi Groups I–IV have been defined previously. Values are given for complex accumulation in PPD1 RNAi Groups I–IV based on the signal from immunodetection. cyt, cytochrome; M, monomer; D, dimer; T, trimer.
