Using biotechnology to protect the environment and investigating its environmental impact
It has been predicted that genetic manipulation, a method that successfully modifies a portion of an organism's distinctive genes, will lead to technological innovation in both basic science and industry. Although there has been significant discussion regarding the safety of this technology, it has made amazing development and is now widely utilised as a basic technology in a variety of disciplines, including basic research and industries including medical, industry, and agriculture. There is a rising trend to use genetically modified organisms in open systems outside of management zones, such as natural habitats. Historically, the handling of genetically modified organisms (GMOs) and the organisms themselves has been restricted to closed management areas. Tomatoes that have undergone genetic modification have undergone open-field trials in Japan and are currently being grown there. However, there are still a number of limitations when growing and using genetically modified organisms outside because there is still a lack of understanding about how they interact with the environment and how this affects them. Furthermore, genetically altered microbes have not yet been subjected to outdoor testing in Japan.
Modern Techniques
Biological creatures have been utilised in the field of environmental conservation to monitor the environment and clean up pollutants, such as employing plants as indicators of air pollution or microorganisms for wastewater treatment and the breakdown of refractory materials. It is feasible to develop new applications for biological organisms and produce indicator and purification organisms that are even more efficient by incorporating genetic manipulation. In any discipline, usable genes must be found from among the known genes or new genes must be identified in order to do genetic modification. This point determines whether or not outcomes can be produced by genetic tinkering. The behaviour of genetically modified organisms in the environment and its effects on ecosystems must be taken into account and predicted in advance in order to use genetically modified organisms in open systems. Standardised testing procedures, however, have not yet been developed.
This unique research project intends to develop techniques to comprehend the behaviour of genetically modified organisms in the environment and their influence on other organisms, as well as valuable organisms for environmental indicators and purification. It was introduced during the fiscal year 1991. Three goals were established for this study: (1) exploration and application of genes for environmental conservation; (2) study of the behaviour of genetically modified organisms and their genes in the environment; and (3) study of the effects of GMOs on ecosystems.
The glutathione reductase (GR) gene from Escherichia coli was used to construct genetically modified tobacco in the study on the investigation and application of genes for environmental conservation, displaying improved resistance to sulphur dioxide and the herbicide paraquat. Additionally, bacteria (Pseudomonas putida) were effectively modified to integrate the enzyme gene for mercury chloride degradation, resulting in the successful development of bacteria with high mercury chloride resistance. This microbe can be used to examine the behaviour of genetically engineered microorganisms because it is easily visible due to its resistance to mercury chloride. Searches for novel genes are currently being conducted in the areas of drought resistance in plants and the breakdown of organic chlorine compounds. The ascorbic acid peroxidase gene will likely be used to make genetically altered plants in the future in an effort to boost drought and air pollution resistance as well as to produce plants with greater GR activity.
In closed growth chambers and semi-open greenhouses, it is examined whether the genetically modified plants developed in (1) grow normally, whether the modified genes are stably transmitted to offspring, and whether the modified genes are transmitted to other plants by pollination or other means, in the research on the behaviour of genetically modified organisms and their genes in the environment and on the impact of genetically modified organisms on ecosystems. Additionally, lysimeters and small flasks modelled after aquatic ecosystems to relatively large water tank sizes and lysimeters modelled after soil ecosystems are developed as microcosms to study the behaviour of genetically modified microbes in the environment. These studies assess the dependability and safety of genetically modified organisms as well as the advantages and disadvantages of using them.
Conclusion:
Actually, the testing procedure should be taken into account on a case-by-case basis, and the usage environment should be unique to each genetically modified organism. However, because specific genetically modified microorganisms and the environments in which they are used cannot currently be identified, and because our understanding of how genetically modified organisms behave in the environment is too limited, it is necessary to begin research as soon as is practical and to build up our knowledge. I intend to re-examine any difficulties with the testing procedure that are discovered through this study and any issues that should be looked at in greater detail.
