In tissue slices from rapidly expanding internodes of sugar cane the vacuolar invertase level is a function of the balance between synthesis and destruction. The enzyme is destroyed in the tissue at an approximately constant rate with a half time of 2 hours. Invertase synthesis is regulated by both auxin and glucose. From studies with inhibitors of protein and RNA synthesis we conclude that auxin alters the rate of synthesis and glucose increases the rate of destruction of messenger RNA required for the production of invertase.
在甘蔗快速伸长节间的组织切片中,液泡转化酶水平是合成和分解平衡的函数。该酶在组织中以大约恒定的速率被破坏,半衰期为 2 小时。转化酶的合成受生长素和葡萄糖的调节。通过对蛋白质和 RNA 合成抑制剂的研究,我们得出结论,生长素改变了合成的速度,而葡萄糖增加了合成转化酶所需的信使 RNA 的破坏速度。
