“…27 Furthermore, molecular studies on these enzymes have been progressed by using genes coded for detoxification enzymes. For example, cytochrome P‐450 species metabolizing chlorotoluron in cultured tobacco S401 cells treated with 2,4‐D were identified as CYP71A11 and CYP81B2 by Ohkawa et al 28…”

To investigate the selectivity and safening action of the sulfonylurea herbicide pyrazosulfuron-ethyl (PSE), pyrazosulfuron-ethyl O-demethylase (PSEOD) activity involving oxidative metabolism by cytochrome P-450 was studied in rice (Oryza sativa L cv Nipponbare) and Cyperus serotinus Rottb. Cytochrome P-450-dependent activity was demonstrated by the use of the inducers 1,8-naphthalic anhydride and ethanol, the herbicides PSE, bensulfuron-methyl, dimepiperate and dymron, or the inhibitor piperonyl butoxide (PBO). Growth inhibition in C serotinus seedlings was more severe than that in rice seedlings. O-Dealkylation activities of PSE were induced differently in rice and in C serotinus, with distinctly higher activity in rice seedlings. The induced PSEOD activities were slightly inhibited by PBO in rice seedlings, whereas they were strongly inhibited in C serotinus seedlings. Dimepiperate and dymron were effective safeners of rice against PSE treatment. Treatments with herbicide alone resulted in less induction of PSEOD activity compared with combined treatments of the herbicide and safener. PSEOD activity in rice seedlings induced with herbicide alone was strongly inhibited by PBO, whereas it was weakly inhibited in rice seedlings induced with combinations of PSE and two safeners. These results suggest that O-demethylation by cytochrome P-450 enzymes may be involved in the metabolism of PSE and may contribute to its selectivity and safening action. Furthermore, these results suggest the existence of a multiple form of cytochrome P-450 in plants.

“…The environmental hazards caused by herbicides can be controlled by plants or crops that are engineered to resist herbicide. [79][80][81] Genetically-engineered crops designed for herbicide resistance provide a positive environmental aspect with the limited use of herbicides [79][80][81], in turn reducing its production expense and limiting the leaching of agricultural waste. A number of plant diseases are triggered by the infection of various viruses, fungi and bacteria.…”

GM crops or Genetically Modified crops are attracted a wide range of media attention in recent years and continues to do so. Media given awareness about the genetically modified crops to public. They reported the uses and drawbacks of the GM crops. The technique offers with regards to the range of advantages of the use of genetically modified crops. In the Pioneer stage of the production of GM crops, two different sectors of concern have been evolved, which includes impact on the agriculture and dangerous to human life. Safety of the eatables have a vital role in the world. The issue can be reduced by enhancing the productivity and quality of the crop. Genetic manipulation technology depends on the MiRNA, it is one of the main problem-solving methods, which influence the environmental product formation through improving major rules used for miRNAs modification and its objectives in GM plants, it contains constitutive, induction to stress, or specific tissue expression of micro RNAs or their aim, RNA gene silencing mechanism, micro-RNA-resistant target and gene expressions. Genetically Modified Organisms is one of the major focuses in biomedical research from 1980s. Since, Genetically Modified models with animal enable researchers for treatment of human genetic diseases. Genetically Modified microorganisms, crops, and animals are used for the production of drugs that are complex by which helps the generation to vaccines that are cheaper. However, this article+ more focused on the human health associated with the genetically modified foods and role of miRNAs in respected to GM food products.

“…The most obvious application of this information is in the development of genetically-modified, herbicide-resistant cro p s with enhanced capacities for herbicide metabolism. This possibility has already been demonstrated in tobacco, where introduction of a cytochrome P 450 gene isolated from soybean, gave resistance to the herbicide, linuron, (Ohkawa et al, 1999;Werck-Reichhart et al, 2000). However, safenerresponsive genes also have a second, less obvious role.…”
