“…The elevated activity on a per Chl basis clearly indicates that delayed membrane synthesis was not responsible for the decreased contents of pigments and PQ. (4). The results of the present work show clearly that, during Cu depletion and resupply, the amounts of Chl, carotenoids, and plastoquinone changed concomitantly.…”

“…Its deficiency in mineral nutrition results in a decrease in photosynthetic activities (5,14). Cu deficiency was found to reduce PSI electron transport and to diminish the plastocyanin content of chloroplasts (4,15). Thus, most investigators believe that Cu deficiency effects on photosynthetic electron transport are mediated via plastocyanin (3,4).…”

“…Cu deficiency was found to reduce PSI electron transport and to diminish the plastocyanin content of chloroplasts (4,15). Thus, most investigators believe that Cu deficiency effects on photosynthetic electron transport are mediated via plastocyanin (3,4). Cu deficiency has other characteristic symptoms which include necrosis and chlorosis (9,11).…”

“…Vesk et al (20) found no ultrastructural alteration between the Cu-deficient and control chloroplasts. Baszynski et al (4) noted some depletion of chloroplast membranes with Cu deficiency. Investigating the effect of Cu deficiency in two different genera, they also found that Cu deficiency decreased the amounts of photosynthetic pigments and lipoquinones to varying extents and concluded that Cu deficiency inhibited the synthesis of these individual chloroplast components differently.…”

The changes in the contents of chlorophyll (Chl) a, Chl b, carotenoid, and plastoquinone in sugar beet (Beta nulgaris) chloroplasts were investigated during Cu deficiency and resupply. With the onset of Cu deficiency, extrachloroplastic Cu decreased more rapidly than chloroplast Cu, which eventually accounted for all of the Cu present in the leaf. The ultrastructure of Cu-deficient chloroplasts did not differ from the control except in very young, severely deficient leaves. During Cu depletion and resupply, Chl a, Chl b, carotenoid, and plastoquinone contents changed concomitantly. Because of the concurrent changes in the contents of terpenoid-containing pigments and plastoquinone with Cu depletion and resupply, we suggest that Cu might be involved in the regulation of the early steps of terpenoid biosynthesis prior to the formation of geranylgeranyl-pyrophosphate.

“…At R Cu 0·05, it was only 17% of that at free access to all nutrients and the difference in NAR was much greater than when N, P or K was the limiting nutrient over the same range of supply (McDonald, Ericsson & Ingestad 1991). The reaction to copper limitation may have been attributable to depression of the content of plastocyanin and its activity in photosystem I (Basyzynski et al 1978), followed by a decrease in photosynthesis and carbohydrate production. This assumption is supported by the finding of lower carbohydrate concentrations at low R Cu (Fig.…”
