Abstract
Environment affects the plants in the different forms of stresses due to which the growth and development of plants are affected. These stresses may be abiotic such as drought, heat stress, and soil salinity or biotic such as pathogen, bacteria and viruses. Some plants have the ability to fight with these stresses by their morphological, physiological and biochemical activities. But all plants do not control the stresses and affected by these stresses and died because of the changes the activities of plant like reduction in the photosynthesis pigments, reduction in the transportation of water to plant parts etc. This review study shows the response of plants toward the different types of stresses by their activities and new technologies (genetic engineering), use of nutrient in the production of plants that can reduce the stress form the plants. Keywords: Abiotic, Biotic, Stress, Nutrient, Genetic Engineering
Introduction
An altered physiological condition due to the alteration in an equilibrium is known as stress. Stress produces physical and chemical changes that is called as strain as when an established condition forces a system to leave its thermodynamic optimal state. Plant growth and other activities (Productivity) are affected by many stresses in nature by changes in their morphological, physiological, biochemical and molecular series. So, plant stress is divided into two category. Biotic and Abiotic Stress.
Biotic Stress
Numerous biotic stresses and adverse environmental conditions are faced by the plants in the term of their morphological, biochemical, and molecular mechanisms. Biotic stresses in plant are the damage which are occur due to bodily entities such as pests, fungi, bacteria, insects, parasites, nematodes, viruses etc. These living organisms are responsible for the plant diseases. According to Wang et al (2013), biotic strain can cause a 37.4% loss of rice, 28.2% yield loss of wheat, 40.3% loss of potatoes, 28.8% loss of cotton, 31.2% loss of maize and 26.3% loss of soybeans. Fungi factor is a biotic stress factor that cause diseases the plant and crop more rather other factors. Besides fungi factor, other micro-organisms can cause plant wither, root rot, leaf spots, and seed impairment.
