In an agricultural area due to continous climatic changes the crops are now prone to abiotic dresses like cold ,drought,salt and heat.What could be the biotechnogical solution to help the farmers of this area?
Biotechnology allows farmers to grow more food on less land using farming practices that are environmentally sustainable. Through biotechnology:
Seeds yield more per acre, plants naturally resist specific insect pests and diseases, and farming techniques improve soil conservation.
Farmers and ranchers can help plants and animals fight diseases and adapt to environmental stress and climate change. We can enhance the nutritional content of foods and improve human health through plant- and animal-produced therapies.
The benefits of biotechnology are especially meaningful at a time when our global population is growing and our demand for food is increasing, especially in developing countries.
Abiotic stress is a primary threat to fulfill the demand of agricultural production to feed the world in coming decades. Plants reduce growth and development process during stress conditions, which ultimately affect the yield. In stress conditions, plants develop various stress mechanism to face the magnitude of stress challenges, although that is not enough to protect them. Therefore, many strategies have been used to produce abiotic stress tolerance crop plants, among them, abscisic acid (ABA) phytohormone engineering could be one of the methods of choice. ABA is an isoprenoid phytohormone, which regulates various physiological processes ranging from stomatal opening to protein storage and provides adaptation to many stresses like drought, salt, and cold stresses. ABA is also called an important messenger that acts as the signaling mediator for regulating the adaptive response of plants to different environmental stress conditions. In this review, we will discuss the role of ABA in response to abiotic stress at the molecular level and ABA signaling. The review also deals with the effect of ABA in respect to gene expression.
growing crops in water-limited environments. Weed control becomes a problem with dry sowing/reduced tillage, but GM crops tolerant to broad spectrum herbicides have enabled farmers to adopt these practices and to meet new weed management issues in a changing climate. Adoption of ”zero tillage,” GM herbicide tolerant crops and GM insect resistant crops directly reduces on-farm operations, in turn reducing fuel use and lowers CO2 emissions.
