Calmodulin and NAD kinase were extracted from serial developmental sections of the pea root apex. Highly purified samples of calmodulin were assayed by NAD-kinase activation, and whole-cell extracts were examined by two-dimensional polyacrylamide gel electrophoresis. Calmodulin was found to vary 17-fold in concentration over the apical 2 mm, being high in the region of the root cap and meristem, falling rapidly at the base of the meristem during early stages of rapid cell elongation. The rate… CONTINUE READING
