玉米耐受低磷胁迫的分子机制研究进展

Progresses on Molecular Mechanisms of Low-phosphorus Tolerance in Maize

玉米是我国重要的粮食、饲料及生物能源作物,低磷胁迫严重影响其品质和产量。近年来,随着高通量测序技术的成熟及组学的发展,关于玉米耐受低磷胁迫的分子机制研究取得了一定进展。主要从玉米耐受磷胁迫相关基因的发掘、组学在研究玉米耐受低磷胁迫中的应用及QTL定位3个方面对玉米耐受低磷胁迫分子机制的研究进展进行了综述,以期为筛选、培育磷高效玉米种质提供理论参考。

Maize is not only a worldwide food and feed crop but also is an important raw material for energy production and many other industrial applications. However,maize yield and quanlity are frequently threatened by phosphorus（P）limitation. The performance of high-throughput sequencing and the progress of omics in plants have shed light on the molecular machnisms of maize tolerance to low-P deficiency. In this review,we concentrates the present progresses of the molecular mechanisms of low-P tolerace in maize,especially on P deficiency induced genes,omics and QTL mapping. This would be useful for improving low-P tolerance of maize varieties.
