Abstract:	We report that growth of Dunaliella salina at either 13°C/150µmol m²s¹ or 30°C/2,500 µmol m²s¹ results in the accumulation of comparable levels ofcarotenoids and the zeaxanthin-binding protein, Cbr. We concludethat carotenoid and Cbr abundance in this green alga respondto changes in PSII excitation pressure ratherthan to high light per se.
