Research paper thumbnail of Oxidative Stress, Reactive oxygen species regulation and ROS scavenging pathways in plants

BioNe- an Ezine of Biological Sciences, 2022

Compilation of the article provides a brief idea about the regulation of intracellular antioxidant defence management systems in response to the intensified generation of ROS in plant cells lead by assortment or variety of stresses.

In fact, the human body is designed to experience stress and react to it. When we experience changes or challenges (stressors), our body produces physical and mental responses. Like humans, the plants also undergo stress and react to it. For example, if a normal plant growing under favourable light conditions is subjected to low light intensity, its photosynthetic mechanism is depleted. Simply, this low light intensity can be referred as a stress factor to the aforesaid plant. The ideal growth conditions for a given plant can be defined as the condition that allows the plant to achieve its maximum growth and reproductive potential as measured by plant weight, height, and seed number, which together comprise the total biomass of the plant. Plants are subjected to various environmental stresses, such as water deficit, drought, cold, heat, salinity and air pollution. The study of functioning of plants under adverse environmental conditions is simply called ‘Plant stress physiology’. Prof. Jacob Levitt in 1972 first used the term biological stress in relation to plants and according to him, stress is simply any change in environmental condition that might adversely change the growth and development of a plant, and also prevents the plant from achieving its full genetic potential.

In these days, although various methods have putted on track to the treatment of the contaminating agents but most of these mechanisms or methods are too sophisticated and expensive to operate practically. Concerning all those things, the use of ‘Phytoremediation’ technique to the treatment of contaminants could be a masterstroke.

Linnaean systems (1707-1778), Adanson system (1763), A.L. De Jussieu (1748-1836), A.P. De Candolle system (1778-1841), G. Bentham (1800-1884) and Hooker (1817). Post-Darwinian classifications viz., Eicher system (1883), Engler & Prantl system (1887-1915), Bessey system (1907), Hutchinson system (1926-1934), Takhtajan system (1966), Cronquist system (1968), Throne system (1968) and APG I,II,III, IV.

Advances In Chemical And Biological Sciences (Volume-1), 2023

These are idiosyncratic sources for pharmaceuticals, food supplements, flavour enhancers, fine chemicals, and other industrial compounds. Secondary metabolites are synthesized especially by certain types of plants. Organized tissue culture practices, more significantly, root cultures can be used in the production of these metabolites from plants, avoiding natural capacity or inconveniences. This chapter will provide a lucid interpretation of the different plant secondary metabolites, with a special emphasis on Phyto-phenols and polyphenols, their potent antioxidant properties, and emerging biopharmaceutical aspects.
