Studies on the development of low-phytate grain, and its application and utilization.

植酸(肌醇六磷酸或InsP6)是磷(P)在种子中的储存形式，以植酸盐的形式存在，通常占种子总磷的75%±10%。植酸不能被单胃动物消化。因此，家禽和鸡粪中存在大量的磷。因此，在谷物消费地区，磷会流失到环境中，在那里它可能会导致土壤和水中的磷含量过高。植酸盐的抗营养作用主要与其六种活性磷酸酯具有很强的螯合活性有关。多价阳离子，如锌和铁，特别敏感，形成不溶于水和难以消化的络合物。为了解决这些问题，我们通过杂交培育了低植酸大豆和高粱，并研究了这个新的低植酸大豆品系与亲本相比的生长特性、生产力和种子品质。

Phytic acid (myo-inositol hexakisphosphate or InsP6) is the storage form of phosphorus (P) in seeds and exists as phytate, typically representing 75±10% of the total seed phosphorus. Phytate is poorly digested by monogastric animals. Therefore, large amounts of P are present in poultry and chicken feces. As a result, P is lost to the environment in cereal-consuming regions, where it may contribute to excessive levels in soil and water. The anti-nutritional effects of phytate are primarily related to its strong chelating activity due to its six reactive phosphorus esters. Multivalent cations, such as Zn and Fe are particularly susceptible and form insoluble and indigestible complexes. In order to address these problems, we developed a low-phytate soybean and sorghum by crossing, and investigate the growth characteristics, productivity, and seed quality of this new low-phytate line compared to the parental stock.
