In 1980 the Supreme Court ruled that a genetically engineered microorganism is eligible for patent protection. 1980年，最高法院裁定通過(guò)基因工程獲得的微生物適合申請(qǐng)專利保護(hù)。
The atrazine-degrading genetically engineered microorganism(GEM) was labeled by transforming a plasmid containing green fluorescent protein(GFP) gene. 通過(guò)轉(zhuǎn)化綠色熒光蛋白基因質(zhì)粒，對(duì)阿特拉津降解基因工程菌進(jìn)行標(biāo)記。
From this, a new research system—delivery of foreign DNA into microorganism via ion beam— was established, offering a new way to construct genetically engineered microorganism. 由此建立起離子注入介導(dǎo)微生物外源DNA轉(zhuǎn)導(dǎo)的研究體系，為微生物轉(zhuǎn)基因工程提供了一條新的途徑。
