摘要 作为植物体内一类关键的信号分子,硝态氮调控了植物生长发育过程中的一系列生物学过程。硝态氮及其信号直接影响着农作物的氮素利用率、产量和品质。因此,深入研究硝态氮信号转导是农业可持续发展的关键。近年来,随着植物分子遗传学、生物化学等学科的迅猛发展,科学家们已经在硝态氮信号的感知、传递以及长距离信号转导等方面取得了许多突破性进展,这将有助于深入了解硝态氮信号如何调控植物生长发育过程中的各个方面。该文综述了近年来国内外有关拟南芥硝态氮信号转导方面的最新研究进展,以期为构建高效利用氮肥的新型农作物提供理论依据。 As a key signal molecule in plants,nitrate modulates a series of biological processes during plant growth and development.Nitrate and its signal directly affect the nitrogen use efficiency(NUE),yield and quality of crops.Therefore,intensive study of nitrate signal transduction is the key to sustainable agriculture.In recent years,with the rapid development of plant molecular genetics,biochemistry and other disciplines,scientists have already made many breakthroughs in nitrate signal perception,transmission as well as long-distance signal transduction,which will provide insight into how nitrate signal regulates various aspects of plant growth and development.In this review,we disscussed the recent advances in nitrate signal transduction in Arabidopsis thaliana,which is expected to provide theoretical basis for the construction of new crops with high NUE.
