氮磷调控根系形态的分子机制研究进展

摘要

根系形态影响植物对营养元素的吸收利用,反过来营养元素也会调控根系的发育.研究营养元素调控根系形态的遗传机制对定向改良根系、培育高效利用肥料的农作物新品种具有重要意义.氮和磷是植物生长所需的大量元素,本文对近年来氮磷调控根系形态的分子机制方面的研究进展进行了综述.%Plant root morphology influences the acquisition of nutrients from soil and is regulated by nutrients conversely.So studying genetic mechanism of root morphology regulated by nutrients is important to improve roots and breed new varieties with efficient utilization of fertilizers.Nitrogen and phosphorous are two necessary major elements for plant growth.The research progresses in molecular mechanism of root morphology regulated by nitrogen and phosphorous were summarized.
