Light-induced potential changes have been measured in the filamentous blue-green alga Phormidium uncinatum both intracellularly and between the two ends ofa trichome. There is evidence that these potential changes are correlated with photophobic reactions in this organism. 1. The potential changes
Transient absorption changes at 43 Β° m/z are induced in aged chloroplasts by red light flashes. The absorption change occurs in lO -4 sec or less and has a half life of approx. lO -2 sec. The enhancement of the reaction by ascorbate and the abolishment by ferricyanide suggest that an oxidation react
