Inhibition of light modulation of chloroplast enzyme activity by sulfite : One of the lethal effects of SO2

Louise E Anderson et al. Oecologia. 1977 Jun.

Abstract

The capacity of a particulate pea (Pisum sativum L.) leaf chloroplast system for light-modulation of enzyme activity is diminished by brief exposure to sodium sulfite and, when intact seedlings are exposed to atmosphric SO2, the same system is inactivated. The destructive effect of this pollutant on green plants may therefore be due to disruption of the mechanism for control of carbon dioxide fixation.
