BACKGROUND 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. RESULTS 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. CONCLUSION 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
