拟南芥硝酸调控基因研究进展

Nitrate regulatory genes in Arabidopsis

氮素是植物生长发育所必需的重要营养成分,它参与植物生长中的许多生理过程,如促进根的生长、调节植物发育等。在植物中,有一个复杂的响应硝酸的系统,但是目前对于硝酸响应和调控机理的研究还很不充分,对参与在硝酸调控信号途径中基因的认识也还很不够。对硝酸调控基因研究,可以为我们解析硝酸信号调控网络提供参考,从而为进一步深入研究植物对硝酸高效利用的分子机理提供理论依据,因此,对硝酸调控基因的研究至关重要。

Nitrate is an essential nutrient,which is involved in many adaptive responses of plants such as localized proliferation of roots.Nitrate could regulate the development of plants.A sophisticated gene network is thought to regulate the responses to nitrate in plants.However,our understanding of the regulatory mechanisms and genes involved in nitrate signaling in plants is incomplete.In the last few years,several nitrate regulatory genes functioning in the primary nitrate response have been characterized.Research for the nitrate regulatory genes will offer insights into the mechanism of nitrate regulation in plants.In addition,it will provide the important directions into the study of high nitrate uptake and utilization efficiency.
