Abstract
Auxin protector-I of the Japanese morning glory is inactivated by manganese. Experiments carried out in vitro indicate that in the absence of oxygen the manganic, but not the manganous, ion rapidly inactivates the protector. It is clear from these, and other data described in this report, and the results of other workers, that in the presence of oxygen, manganese accelerates auxin inactivation by means of 2 separate and distinct mechanisms: 1) manganese catalyzes the oxidation of auxin protectors, and 2) following the inactivation of the protectors, or in the absence of protectors, accelerates the oxidation of indoleacetic acid by endogenous peroxidases.
摘要
日本牵牛的生长素保护素-I 被锰失活。在体外进行的实验表明，在缺氧的情况下，锰离子（而不是二价锰离子）会迅速使保护素失活。从这些实验以及本报告中描述的其他数据和其他研究人员的结果可以清楚地看出，在有氧气的情况下，锰通过两种独立而不同的机制加速生长素失活：1）锰催化生长素保护素的氧化，2）在保护素失活后，或在没有保护素的情况下，加速内源性过氧化物酶氧化吲哚乙酸。
