In the presence of gibberellic acid (GA3) aleurone layers and isolated aleurone protoplasts of Avena fatua accumulate specific isozymes of acid phosphatase (EC 3.1.3.2). Some of these may be involved in mobilizing aleurone-grain phosphate reserves during germination. The hormone also controls secretion of other specific molecular forms of the enzyme that probably assist in endosperm hydrolysis. The accumulation and secretion of putative cell-wall-associated isozymes are stimulated by the action of GA3 in isolated protoplasts. This effect however, is apparently over-ridden in the intact tissue, possibly by a cell-wall-based feedback mechanism.
在赤霉素（GA3）的存在下，野燕麦糊粉层和分离的糊粉层原生质体积累酸性磷酸酶（EC 3.1.3.2）的特异性同工酶。其中一些同工酶可能参与在萌发过程中动员糊粉层-谷物磷酸盐储备。该激素还控制其他特定分子形式的酶的分泌，这些酶可能有助于胚乳水解。在分离的原生质体中，GA3 的作用刺激了假定的细胞壁相关同工酶的积累和分泌。然而，在完整的组织中，这种效应显然被细胞壁为基础的反馈机制所掩盖。
