The quantitative relationship between reaction centers I and II was studied with blue-green algae Anabaena cylindrica, Anabaena variabilis and Anacystis nidulans grown under different light conditions. The number of reaction centers I was estimated from the P700 content and that of reaction centers II, from the O_2 yield of repetitive short flashes. Supplementary determinations were done with three other blue-green algae and one red alga. The maximum number of reaction centers II counted from the O_2 yield of repetitive short flashes was markedly smaller than the total number of P700 in all algae tested when the algae were grown under weak light; in the extreme case (Anabaena cylindrica), the ratio was only 0.258±0.015. This ratio became larger and close to unity when the algae were grown under stronger light. Variation in the number of reaction centers in a single cell suggested that reaction center I was a variable component. Our results indicate that the proportion of the two reaction centers may markedly vary in blue-green algae depending on the growth conditions.
