RISKS AND RISK ASSESSMENT OF GM CROPS WITH ADVANCED MODIFICATION TECHNOLOGIES

Abstract

Genetically modified organisms (GMOs) are organisms whose genetic material (DNA) has been artificially modified by using genetic engineering techniques to enhance and altered their characteristics. Genetic engineering plays a significant role in the development of transgenic crops. The four crops canola, maize, cotton, and soybean are the most common ones to use GM crop technology, which has been used extensively for more than 20 years in a variety of nations. The two most significant GM crops in Pakistan are cotton and maize, both of which are resistant to weeds and insects. The impact studies of insect-resistant and herbicide-tolerant crops that are already available demonstrate the advantages of these techniques for both producers and consumers, as well as their favorable effects on both the environment and public health. Additionally, GM crops are a treatment for famine and malnutrition. Future uses may perhaps provide even greater benefits. Implementing an integrated strategy to pest management will be essential for food security, agricultural stability, and protection of the environment as the global population increases. Crops that have been genetically modified (GE) offer resistance to herbicides or protection from pests and diseases. Technology significantly decreases pest damage and improves crop production. As in the case of Bt cotton, pestresistant genetically modified crops can support higher yields and agricultural development. We provide a thorough update on the status of the cultivated genetically modified (GM) crops in this paper. We address some vector based techniques for modification and some new approaches of transgene transfer without microbial vector insertion into recipient species In order to reduce the hazards associated with microbial vectors.
