Secretion-the outward movement of molecules across the plasmalemma-of alpha-amylase by barley (Hordeum vulgare L. cv. Himalaya) aleurone layers is an energy-dependent process that is not directly dependent upon protein synthesis or RNA synthesis and does not appear to be under the direct control of gibberellic acid or abscisic acid. Release-the movement of the secreted alpha-amylase molecules through the walls into the surrounding medium-is apparently diffusion limited and is markedly dependent upon the presence of ions.
大麦(Hordeum vulgare L. cv. Himalaya)糊粉层分泌α-淀粉酶(即分子穿过质膜向外移动)是一个能量依赖过程,该过程不直接依赖蛋白质合成或RNA合成,且似乎不受赤霉素或脱落酸的直接控制。释放(即分泌出的α-淀粉酶分子穿过细胞壁进入周围介质的移动)显然受扩散限制,并且明显依赖于离子的存在。
