In this article we will discuss about the role of dark-fixation of CO2 in plants. In several plants a highly specialized cellular adaptation in most of the developmental systems exists in which dark-fixation of CO2 utilizes phosphoenolpyruvate (PEP) derived from carbohydrates as a substrate plays a vital role (Fig). Malate produced from dark fixation of CO2 acted as an osmoregulatory [...]
Get the answer of: How Plants are Damaged through Stress ? Stress is a mechanical concept and defined as a force per unit area applied to an object. The object develops a strain in response to a specific stress. Compared with mechanical systems, in biological systems it is difficult to define stress precisely. Even though applicable in mechanical terms, its [...]
In this article we will discuss about the contribution of plant physiology towards crop improvement. Food is an essential requirement, and the demand for food shall keep on increasing with the increase in population. Till recently the increase in the rate of production of food matched or even exceeded the population growth rate. The classical breeding programmes have contributed enormously [...]
