In addition to the alterations in the normal water economy of the whole plant, many pathogens have ability to alter the normal water relations of individual cells. We know that plasma membrane permeability plays a vital role in inward and outward movement of substances and controls cell water relations in plants. Plasma membrane is a […]

Effect of Pathogens on Plant Growth Regulation | Botany
Article shared by :
Growth of plants, in general, is effected by environmental conditions, but its fundamental processes such as cell-division and differentiation operate under the regulation of certain hormonal compounds — auxins (IAA), gibberellins, cytokinins, and ethylene. Any alteration in the concentration and distribution of these hormonal compounds affects widely the growth physiology of plants. All plant pathogens, […]

Photosynthesis, the only process of food synthesis using light energy on the earth, is the distinctive physiological activity of green plants. In spite of its fundamental significance, comparatively little is known about the effects of pathogens on photosynthesis. Main attention has been paid to the effect of the pathogen on the overall rate of photosynthesis […]
