General Trends on the Use of Microorganisms in Both Organic Farming and Genetic Engineering

A developing country desires that its poverty be alleviated and food security be experienced by its citizens. Given in its setting are such seeming liabilities as indiscriminate population growth, land degradation and increasing food demand, difficulty in sustaining agriculture production through improved soil quality management. If to this scenario will enter an almost perfect system – an agricultural system that maintains and improves human health, benefits producers and consumers both economically and spiritually, protects the environment, and produces enough food for an increasing world population – then the whole stage appearance will be plausible.
How is this stage coming alive today?
Plant growth promoting rhizobacteria (PGPR) and cyanobacteria strains are seen as possible candidates for genetic enhancement so as to offer an environmentally sustainable approach to increase crop production and health. Furthermore, revelations about the mechanisms of PGPR action open new door to design strategies for improving the efficacy of biocontrol agents. There is an urgent need to conduct studies under field conditions.
Genetic manipulation of host crops for root-associated traits to enhance establishment and proliferation of beneficial microorganisms is being pursued. Health and safety testing are also required to address such issues as the non-target effects on other organisms including toxigenicity, allergenicity and pathogenicity, persistence in the environment and potential for horizontal gene transfer.
There is a need to have an environment that supports high populations of beneficial soil microbes and activities related to biological control. Because it has been observed that disease suppression in plant typically occurs as a result of the activation of the indigenous soil microbial com-munity, which has been much neglected in favor of intensive research on individual antagonistic microorganisms.
The encapsulation of microbial inoculants for agricultural purposes has a potential for succeeding. It has been shown to be advantageous over using liquid inoculants, peat, and clay. However, the inconvenience of bioencapsulation technology must not be ignored. To produce a large amount of inoculant, trials on large fields are required to use innovative bioencapsulation devices.
The use of arbuscular mycorrhizal (AM) fungi and Rhizobium increases the nitrogen and phosphorus uptake and in turn reduce the use of agrochemicals. The agrochemicals are very costly and had side effects on human health and environment. With the use of these symbionts farmers can save the capital and can achieve sustainable agriculture.
Suffice it to say that genetic engineering, when accomplished by mystic scientists, can impact more benefits to organic farming and all consumers in general.
