Specific Loss of LHCII Phosphorylation in a Chlamydomonas Mutant Lacking the Cytochrome b6/f Complex
Recent studies in our laboratory have indicated that the cytochrome b6/f (cyt.b6/f) complex is involved in the light induced phosphorylation of LHCII polypeptides in Acetabularia and Lemna (1,2). Similar data have been obtained with several cyt.b6/f deficient Chlamydomonas (3) and maize mutants (4,5). To further ascertain that indeed the cyt.b6/f complex is required for the activation of the redox controlled LHC II kinase, the activity of this enzyme(s) was assayed in another Chlamydomonas mutant lacking the complex components.
