Selection and genetic modification of plants for phytoremediation of soils and aqueous media.

摘要

Selection and genetic modification of plants for phytoremediation of soils and aqueous media.; Has become first a plant species conferring important properties for phytoremediation soil and aqueous media; the species Nicotiana glauca genetically modified done that phytoremediation reasonable periods of time. The TaPCS1 gene encoding a protein having phytochelatine synthase function is introduced. Wheat introduced gene expression level has a permanently increased. Such modified Nicotiana glauca plants are a generally resistant to weather and environmental edafología own flora, it is very competitive in "pseudonormal" situations of excess metals and resists well the water and nutritionalstress.; Such genetically improved plant growth provides faster and has a higher biomass than wild plants; also a superior absorbability of various metals. It is indicated for phytoremediation soil and aqueous media.
