Treatment of isolated barley aleurone layers with gibbcrellic acid (GAs) resulted in a progressive inhibition of cell-wall synthesis after a 4-h lag period. The incorporation of both [ltCJarabinose and [14CJglucose into the cell wall was inhibited by GA 3, but analysis of the labelled sugars in the

Using isolated lettuce seed embryos it can be shown that the inhibitory effect of abseisic acid upon germination is reversed solely by cy~okinin. In the intact seed, however, gibberellic acid is also required for this reversal to be manifested in germination.
The steady-state levels of Ca(2+) within the endoplasmic reticulum (ER) and the transport of (45)Ca(2+) into isolated ER of barley (Hordeum vulgare L. cv. Himalaya) aleurone layers were studied. The Ca(2+)-sensitive dye indo-1. Endoplasmic reticulum was isolated and purified from indo-1-loaded proto
