Recent research shows that signals derived from nitrate are involved in triggering widespread changes in gene expression, resulting in a reprogramming of nitrogen and carbon metabolism to facilitate the uptake and assimilation of nitrate, and to initiate accompanying changes in carbon metabolism. These nitrate-derived signals interact with signals generated further downstream in nitrogen metabolism, and in carbon metabolism. Signals derived from internal and external nitrate also adjust root growth and architecture to the physiological state of the plant, and the distribution of nitrate in the environment.
最近的研究表明，源自硝酸盐的信号参与触发基因表达的广泛变化，导致氮和碳代谢的重新编程，以促进硝酸盐的吸收和同化，并引发碳代谢的相应变化。这些源自硝酸盐的信号与氮代谢和碳代谢中更下游产生的信号相互作用。源自内部和外部硝酸盐的信号还会根据植物的生理状态以及环境中硝酸盐的分布来调节根系生长和结构。
