It is a constituent of the primary electron donor in photosystem I, the Cu-protein plastocyanin. Many authors have also described Cu as a constituent of photosystem II (PSII). However, high Cu concentrations inhibit the photosynthetic electron transport, especially in PSII. In add
ition, both Cu deficiency and Cu toxicity interfere with pigment and lipid biosynthesis and, conquently, with chloroplast ultrastructure thus negatively influencing the photosynthetic efficiency. In this review, the different functions propod for the metal in PSII are reviewed. With reference to the effect of toxic Cu on PSII, the polemic results concerning its mechanism of action and Cu-binding sites are discusd. Other effects of Cu toxicity
