转基因烟草就是利用转基因技术应用到烟草植物的种植中。把吞噬毒素的生物基因嫁接到了烟草植物身上。最新研究表明，转基因烟草具有清理汞污染严重的土壤，吸收军事TNT污染的功能方面与清除RDX（旋风炸药）以及获取了防艾滋病病毒抗体2G12的功能。因此具有重要的价值。
用农杆菌介导的叶盘法将HAL1基因转入模式植物烟草，对转基因烟草的耐盐性进行评价；
The HAL1 gene was transformed into tobacco by Agrobacterium through leaf disc transformation and the salt tolerance character of transgenic tobacco was analysised.
通过农杆菌介导，采用叶盘法将豌豆凝集素基因转化单倍体烟草，获得了转基因再生植株。
The pea lectin gene was transformed into the haploid tobacco via Agrobacterium mediation using leaf disc method and the regenerated tobacco plants were obtained.
