title: The action of exogenous gibberellic acid on protein and mRNA in germinating castor bean seeds.
abstract: Gibberellic acid (GA3) stimulates water uptake in castor beans and increases the activity of certain enzymes associated with lipid mobilisation.The effect of the GA3 on the enzymes is possibly due to a general effect of the growth substance on protein synthesis. Gibberellic acid advanced the appearance of rRNA and poly (A(+))RNA in castor bean endosperms without specifically stimulating the synthesis of particular mRNA species. Thus these increased levels of mRNA and rRNA may act synergistically to affect the rate of a predetermined pattern of protein synthesis.
