The field of biotechnology has extraordinarily influence on science, law, the administrative condition social insurance, and business. As the starting of agriculture, people have been manipulating crops to improve the yield and quantity. Product yields throughout the world are essentially diminished by the activity of herbivorous insects, pathogens and parasites. Natural environmental stresses make this circumstance significantly worse. Abiotic stresses are the important factors for crop development and improvement, causing massive yield losses over the worldwide. Many mechanisms have been utilized for engineering abiotic stress tolerance in model and other crop plants by means of established biotechnological and/or breeding techniques. The use of genetic engineering technology improvement to particular characteristics is then discussed about, including input aspects identifying with control production (herbicide and insects resistance, protection from pathogens and abiotic stresses). Crop improvement has been improved the many years by means of conventional plant breeding strategies or over different physical, chemical compound (e.g., gamma radiation, ethyl methane sulfonate) and other biological techniques (e.g., T-DNA, transposon insertion) primary to point mutations, rearrangement, duplication and insertion. Zinc finger nucleases have been effectively utilized in genome modification of different plants including tobacco, maize, soybean, and so on. The understanding of molecular basis of plant reaction to these natural environments or stresses has been an important focal point of research in the past decades. Genetically modified organisms are being utilized to lessen the yield loss because of different stresses (biotic and abiotic) and are being utilized broadly for value increase in food crops by improvement with quality proteins, vitamins, zinc, carotenoids, anthocyanin, iron and many more. Incorporation of modern biotechnology, with regular traditional practices in a sustainable way, can fulfill the objective of achieving food security for present and as well as in future.
