Exposure of Dunaliella salina to low temperature mimics the high light-induced accumulation of carotenoids and the carotenoid binding protein (Cbr)

sults in the accumulation of comparable levels of carotenoids and the zeaxanthin-binding protein, Cbr. We conclude that carotenoid and Cbr abundance in this green alga respond to changes in PSII 'excitation pressure' rather than to high light per se.
