Inhibition of cell enlargement

Metabolic disruptions may result in inhibition of cell enlargement. Key (9) found that actinomycin D, an inhibitor of DNA directed RNA synthesis (10), and puromycin, an inhibitor of protein synthesis, will prevent cell enlargement in soybean Glycine max L. Merr.) hypocotyls. Key concluded RNA and protein synthesis are essential for the process of cell elongation to proceed at a normal rate. The following year, Cleland reported the inhibition of cell enlargement caused by actinomycin D was not caused by an inhibition of auxin-induced cell wall loosening...
