In this article we will discuss about:- 1. Definition of Phytoremediation 2. Transgenic Plants for Phytoremediation 3. Transgenic Approach. Definition of Phytoremediation: Extensive activity of mankind has been introducing hazardous compounds into the environment at an alarming rate. The soil has been contaminated with toxic materials which is jeopardising its fertility. Heavy metals accumulation is primary concern because they cannot [...]
In this article we will discuss about the examples of transgenic plants for phytoremediation. 1. Phytoremediation of Mercury: There have been reports on the ability of certain plant species which have ability to accumulate mercury both from atmospheric and soil sources. However, plant species never ventured hyper accumulation of mercury, researcher use engineered plants by introducing bacterial specific genes for [...]
This article throws light upon the three main areas of application of phytoremediation. The areas of application are: 1. Phyto-Extraction of Metals 2. Phytovolatilisation of Metals 3. Phytodegradation of Metals. Application # 1. Phyto-Extraction of Metals: A review of the phytoremediation literature reveals that, at present, there are two basic strategies of phyto-extraction being developed: chelate-assisted phyto-extraction, which we term [...]
