The process of adding a gene to a DNA manually into an organism is called transgenic engineering. Farmers have been using this process for decades in agriculture. Although farmers didn’t really know the true knowledge to explain these changes occurring to their crops, they sure did know it was benefiting the market back then thus they continued to experiment on different crops to produce new genetically modified products. With the help of technology scientist figured out what were the reason of these
Genetic diversity of crops is the foundation for sustainable agriculture/ horticulture and global food security. Conservation and sustainable utilization of agro-biodiversity plays vital role in ensuring food security, alleviation of poverty and enhancing livelihood measures. It has potential for employment generation and risk minimization. Maintenance of crop diversity is more remunerative as compared to monoculture. The ability of certain land races to withstand drought, grow in poor soil, resist
Plants have to deal and interact with various complex types of environmental factors. Exposure of plants to abiotic and biotic stress induces a disruption in plant metabolism implying physiological costs (Bolton, 2009; Massad et al., 2012) and thus leading to a reduction in productivity (Shao et al., 2008). Environmental stress is one of the most important features which have enormous impact on growth and yield potential of crops. Consequently, it is responsible for severe losses in the field. Only
content. Weeding, on the other hand, is far more labor intensive than using herbicides, and the area available for growing crops is reduced significantly when nitrogen-fixing plants are used as part of crop rotation. Crop rotation is also one of the techniques that organic farmers use, which is beneficial since it reduces plant disease and minimize damage to soil composition. Unfortunately, this results in lower production and an inefficient method of growing different types of crops. For years, people
in our food has been a controversial topic for many decades. Genetically modified organisms (GMOs) are defined as organisms with genetic material altered using genetic engineering. The use of GMOs is not something very new. The most common form of modification is selective breeding, which has been used for thousands of years to enhance certain desired traits in plants and animals. Many people have a hard time deciding whether or not GMOs are advantageous or disadvantageous to the human population
Further, rice productivity is continually threatened by both biotic (bacterial blight, blast, tungro virus, yellow mottle virus, sheath blight, etc., and insects like plant hoppers, stem borer, and gall midge), and abiotic stress (drought, salinity, submergence, cold, heat, soil toxicities, etc.). One of the major challenges facing agriculture today is the global water shortage caused by the increasing world
Benefits and Risks of Biotechnology Biotechnology is technology applied in biology to improve lives and health in society. It is technology that harnesses cellular processes . These cellular processes can be applied in healthcare, agriculture, and industry to improve their effectiveness and efficiency . Biotechnology has a very heavy influence on life today . Healthcare Biotechnology is already benefitting over 350 million patients globally and treats heart attacks, strokes, breast cancer, leukemia

2.2. CONCEPT OF BIODIVERSITY It has been estimated that more than 50 million species of plants, animals and micro-organisms are existing in the world. Out of these, about 1.4 million species have been identified so far. Each species is adapted to live in specific environment, from mountain peaks to the depth of seas, from polar ice caps to tropical rain forests and deserts. All this diversity of life is confined to only about one kilometre thick layer of lithosphere hydrosphere and atmosphere which
