In this short review, basic processes for phytoremediation and plant enzymes that are potentially useful in phytoremediation are briefly summarized. The remaining part describes the applications of the basic processes to decontaminate pollutants in the environments that have been done in our laboratory. Our work includes (1) analysis of the capability of various naturally occurring plants to decontaminate atmospheric nitrogen dioxide and selection of nitrogen-dioxide-philic plants that grow with nitrogen dioxide as the sole nitrogen source, (2) production of transgenic plants to improve plants' capability to decontaminate atmospheric nitrogen dioxide, and (3) analysis of the denitrification process in plants to innovate a gas--gas-converting plants that convert nitrogen dioxide to nitrogen gas.
在这篇简短的综述中，简要总结了植物修复的基本过程以及在植物修复中可能有用的植物酶。其余部分描述了这些基本过程在我们实验室中用于净化环境中污染物的应用。我们的工作包括：（1）分析各种天然植物净化大气中二氧化氮的能力，并选择以二氧化氮作为唯一氮源生长的亲二氧化氮植物；（2）培育转基因植物以提高植物净化大气中二氧化氮的能力；（3）分析植物中的反硝化过程，以创新一种将二氧化氮转化为氮气的气-气转化植物。
