Abstract
Washing of excised corn (Zea mays L., variety WF9xM14) root tissue is accompanied by an increase in (Mg(2+) + K(+))-stimulated adenosine triphosphatase. This is the adenosine triphosphatase described by Fisher, Hansen, and Hodges as positively correlated with ion accumulation rates. The increase in activity is confined to the microsomal fraction. A close parallel exists between increases in adenosine triphosphatase and phosphate absorption, and they respond similarly to inhibitors of RNA and protein synthesis. However, the amplitude of change is much smaller in adenosine triphosphatase. Possible reasons for this discrepancy are discussed.
摘要
切除的玉米（Zea mays L.，品种 WF9xM14）根组织的洗涤伴随着（Mg(2+) + K(+))刺激的三磷酸腺苷酶的增加。这是 Fisher、Hansen 和 Hodges 所描述的与离子积累率呈正相关的三磷酸腺苷酶。活性的增加仅限于微粒体部分。三磷酸腺苷酶的增加与磷酸盐吸收之间存在密切的平行关系，它们对 RNA 和蛋白质合成抑制剂的反应也相似。然而，三磷酸腺苷酶的变化幅度要小得多。对此差异的可能原因进行了讨论。
