Chloroplast thylakoid protein phosphorylation was discovered, and the most conspicuous phosphoproteins iden-
tified, by John Bennett at Warwick University. His initial findings were published in 1977. The phosphoproteins
included apoproteins of chloroplast light harvesting complex II. Thylakoid protein phosphorylation was shown to
influence distribution of excitation energy between Photosystems I and II in 1979, during a visit by Bennett to
the laboratory of Charles J. Arntzen at the University of Illinois at Urbana-Champaign. That work was published
