The Plasma Membrane of Avena Coleoptile Protoplasts ' Received for publication
Treatment of living protoplasts from the Avenia coleoptile with enzymes and chemicals has provided new information about the external surface of the plasma membrane. Treatments with selected detergents and polyene antibiotics indicate that little sterol is present. The lysis of protoplasts in carboxymethyl-RNase which is enzymatically almost inactive provides strong evidence that the lysis prev...

متن کاملSecond positive phototropism in the Avena coleoptile.
A method has been developed whereby the second positive phototropism can be observed separately from the first positive and negative phototropic responses which also occur in oat coleoptiles. Although the second positive phototropic response has often been referred to as the base response, photoreception for it is shown to occur mainly in the apical 3 mm of the coleoptile. The Bunsen-Roscoe rec...

متن کاملThe Growth and Respiration of the Avena Coleoptile
1. Transport of the plant growth hormone into the Avena coleoptile as well as the action of the hormone on cell elongation in the coleoptile are shown to depend upon aerobic metabolism. 2. Crystalline auxine, in contrast with impure preparations, affects neither the magnitude nor the respiratory quotient of coleoptile respiration. 3. Increasing age of the coleoptile cell decreases its rate of e...
