Phytic acid as a phosphorus storage vault provides phosphorus for plant development. It is an anti-nutritional factor for humans and some animals. However, its degradation products lower inositol phosphates have positive effects on human health. In this study, the effect of gibberellic acid (GA) on phytic acid degradation under calcium lactate (Ca) existence was investigated.
The results showed that Ca + GA treatment promoted the growth status, hormone metabolism and phytic acid degradation in germinating soybean. At the same time, the availability of phosphorus, the activity of phytic acid degradation-associated enzyme and phosphoinositide-specific phospholipase C (PI-PLC) increased. However, the relative genes expression of phytic acid degradation-associated enzymes did not vary in accordance with their enzymes activity.
The results revealed that GA could mediate the transport and function of calcium and a series of physiological and biochemical changes to regulate phytic acid degradation of soybean sprouts. © 2017 Society of Chemical Industry.
植酸作为一种磷储存库为植物生长发育提供磷。它是人和一些动物的抗营养因子。然而，其降解产物低肌醇磷酸酯对人体健康有积极作用。本研究考察了赤霉素（GA）在乳酸钙（Ca）存在下对植酸降解的影响。
结果表明，Ca + GA处理促进了发芽大豆的生长状况、激素代谢和植酸降解。同时，磷的有效性、植酸降解相关酶及磷脂酰肌醇特异性磷脂酶C（PI-PLC）的活性增加。然而，植酸降解相关酶的相对基因表达与其酶活性并不一致。
结果表明，GA可介导钙的转运和功能以及一系列生理生化变化来调控豆芽的植酸降解。© 2017化学工业协会。
