摘要
毛状根组织是由农杆菌转化植物外植体获得的转基因组织,具有培养简单、生长速度较快、遗传性状和表型特征稳定等优点。近年来毛状根组织在植物修复技术中的应用研究引起了研究者的关注,毛状根组织被作为根的模式体系越来越多地应用于重金属和有机污染物的植物修复技术研究中,已日益成为植物修复技术研究中的一种便捷的实验室研究工具。本文综述了毛状根组织在植物修复中的应用研究进展,包括农业领域重金属污染物的富集,工业领域酚醛、染料和PCBs污染物的去除,军事领域TNT和放射性核素污染物的降解,医药领域抗生素污染物的消除等,并对毛状根组织在植物修复技术研究中的应用前景进行了展望。
Hairy root tissue is a kind of genetically modified (gm) tissue that is obtained by agrobacterium transforming the explant of plants, having the traits of simple cultivating, fast growing, stable genetic and phenotypic characteristics, etc. Recent years the application of hairy root tissue in phytoremediation technology has caused the attention and the hairy root tissue as the model of root system has been increasingly used in the study of the phytoremediation of heavy metals and organic pollutants. Results indicate that hairy root tissue gradually becomes a convenient laboratory research tool in the study of phytoremediation technology. The application and research progress of hairy root tissue in the phytoremediation was reviewed in this paper, including enrichment of heavy metals pollutants in agriculture field;elimination of phenolic, dye, and PCBs pollutants in industry field;degradation of TNT and radionuclide pollutants in military field;remove of antibiotics pollutants in medical field, etc. And the prospects of hairy root tissue used in the phytoremediation research were also discussed.
