S ummary Glutamate metabolism in intact cotyledons of pea seedlings ( Pisum sativum L.) differs considerably from that in cotyledon slices. No decarboxylation of glutamate was found in intact cotyledons, whereas the decarboxylation in sliced cotyledons was so large that γ‐aminobutyric acid (γAbu) was by far the predominant metabolic product of glutamate. A number of mechanisms that could trigger glutamate decarboxylase activity are discussed.
