Regulation of Assimilatory Nitrate Reductase

同化硝酸还原酶的调节：Solomonson博士建议阐明在调节硝酸盐同化中起作用的调节机制。这是植物将土壤中的硝酸盐转化为可用有机氮的过程。在藻类模型系统中，他将使用分子和生化技术来了解光强、氧气、二氧化碳、硝酸盐和固定氮素的浓度如何影响细胞活动。硝酸还原酶是硝酸盐同化过程中的关键酶，是植物界土壤和肥料中无机氮转化为有机氮的主要过程。全球食物蛋白质的净产量最终在很大程度上取决于硝酸盐的同化作用。了解硝酸还原酶在绿藻小球藻中是如何调控的，肯定会增加我们对这种酶在整个植物界是如何调控的知识。因此，这项研究的结果不仅具有根本性的重要性，而且在未来也可能具有重要的农学意义。

Regulation of Assimilatory Nitrate Reductase: Dr. Solomonson proposes to elucidate the regulatory mechanisms operative in the regulation of nitrate assimilation. This is the process by which plants convert nitrate in soil to usable organic nitrogen. In an algal model system he will use molecular and biochemical techniques to learn how cellular activity is affected by light intensity, concentrations of oxygen, carbon dioxide, nitrate and fixed nitrogens. Nitrate reductase is the key enzyme in nitrate assimilation, the major process responsible for the conversion of inorganic nitrogen of soil and fertilizer to organic nitrogen in the plant kingdom. The net global production of food protein is eventually dependent in large part on nitrate assimilation. Understanding how nitrate reductase is regulated in the green alga, Chlorella, will certainly increase our knowledge of how this enzyme is regulated throughout the plant kingdom. Thus the results of this study will not only be of fundamental importance but may also in the future be agronomically significant.
