Abstract
The effects of sulphur deficiency on the expression of storage-protein genes in developing pea (Pisum sativum) cotyledons were studied. Legumin-gene transcription was decreased by S-deficiency, but not to the same extent as the decrease in the level of legumin mRNA. Vicilin-gene transcription was not significantly affected. Control of gene expression may thus occur during transcription and/or post-transcriptional events.
