Current research on suitable mechanisms on different plant genotypes under phosphorous stress condition

摘要: 提高磷(P)效率的途径之一是选择在P胁迫下能实现高产的新的基因型植物。阐述了低P胁迫下植物根的粗细，根毛的数量和密度，侧根的数量，根系特异分泌物种类数量的差异，酸性磷酸酶活性等形态和生理方面的适应性反应，与耐低P有关的基因定位、克隆的研究进展，揭示了植物低P胁迫时的适应机制。

Abstract: One of the ways to increase phosphorous efficiency is to select new plant genotypes, which can achieve high yield in phosphorous stress condition. This article deals with the changes of plant root morphology,physiology and genetic characters in order to illustrate the mechanisms in low P condition and lay the foundation of selecting new plant genotypes in agriculture.
