N2 - This study investigated temporal variations in the potential maximum quantum yield of photosystem II (Fv/Fm ratio) and growth-phase dependent cellular protein expressions of Chattonella antiqua under laboratory conditions. Despite the culture conditions, significant positive correlations between the Fv/Fm ratio and daily growth rate were observed. Threshold Fv/Fm ratios associated with positive cell growth were calculated to be >0:44, >0:44, and >0:37, and those associated with active cell growth (growth rate >0:5 div. d-1) were >0:58, >0:60, and >0:49 under control culture, low nutrient and intense light conditions, respectively. Proteome profiles obtained by two-dimensional gel electrophoresis (2-DE) indicated that 42 protein spots were differentially expressed at various growth phases of C. antiqua, which indicates changes in cellular physiological status throughout the growth cycle, and suggests that oxygen evolving enhancer 1 and 2-cysteine peroxiredoxin play roles in maintaining the positive growth of C. antiqua.
