Studies are continuing concerning the rate inhibition induced by treating chloroplasts with glutaraldehyde. The decay of activity of isolated chloroplasts stored in the dark is studied as a function of pH. The program concerning the size of the photosynthetic unit in relation to the utilization of high light includes studies of nitrogen-starved algae and the possible role of carotenoids which accumulate in these cells. The authors detect no specific photochemical process driven by carotenoid in these organisms. Comparative studies of the light gathering systems in the bundle sheath and mesophyll cells of C/sub 4/ plants are initiated. In the mass spectrometer program, measurements are made of the affinity of O/sub 2/ for photosynthetic reducing power. Half saturation of the oxidative reaction is at approximately equal to 8% O/sub 2/. Studies of the kinetics of O/sub 2/ uptake under conditions of low CO/sub 2/ are also performed.
