Bean Leaves

Etiolated bean leaves supplied δ-amino-levulinic acid in the dark synthesize large amounts of protochlorophyllide which is not converted to chlorophyllide upon illumination of the leaves. The fine structure of the proplastids is not affected by the treatment. When leaves containing "inactive" protochlorophyllide are exposed to light of 700 ft-c for 3 hours, they lose practically all their green pigments. During this period large stacks of closed membrane structures are built up in the region of the prolamellar body. These lamellar structures remain even when no or only traces of pigment are left in the leaves. In untreated control leaves the pigment content remained constant during similar illumination and the structural changes in the plastids consisted of a rearrangement of the vesicles from the prolamellar bodies into strands dispersed through the stroma; lamellae and grana formation occurred later.

Harmful Effects

The activity of red cell δ-amino levulinic acid dehydratase of rainbow trout (Salmo gairdneri) was depressed after exposure of the fish to lead. Concentrations of lead in water as low as 13 μg/liter caused a significant inhibition of activity after only 4-wk exposure. Assays of this enzyme’s activity may provide a short-term indication of long-term harmful effects of lead.
