【摘要】 磷是影响植物生长和发育的重要大量元素之一。土壤中有效磷含量很低,限制了大豆生长,在磷胁迫下大豆会产生一系列适应性的变化。大豆如何适应低磷胁迫环境和高效吸收利用土壤中有限的有效磷已经成为当前的研究热点。文章综述了低磷胁迫下,大豆植株形态、生理生化指标的变化,基因水平的差异表达和磷胁迫下mRNA的表达,并对大豆对磷胁迫响应研究方向作了分析与展望,以期为大豆耐低磷研究及磷高效大豆品种改良提供理论依据和新思路。更多还原

【Abstract】 Phosphorus(P)is one of the major element in the process of plant growth and development.The lower soil effective phosphorus content seriously limited soybean growth.Under phosphorus stress,soybean will produce a series of adaptive physiological changes.This paper reviewed the physiological,biochemical changes,differences in gene expression and mRNA expression of soybean under low phosphorus stress.We hope for providing a theory basis on studying the mechanism of low P adaption and selecting of P-efficient soybean variety.更多还原
