Abstract
The properties of a newly observed light-induced absorbance change in the 600-m[mu] region in green plants [algae, Swiss chard] are described. The spectrum of this absorbance change fits very well with the oxidized-minus-reduced spectrum of purified plastocyanin in vitro. It is also demonstrated that the light-induced increase of absorbance corresponds to an oxidation and that far-red light, 713 m[mu], is more effective than red, 651 m[mu], in causing it. An antagonistic effect of red and far-red light on this absorbance change is also reported. It is suggested that plastocyanin might be a link between the 2 photochemical systems of photosynthesis.This publication has 4 references indexed in Scilit:
