Causes Of Oxidative Stress In Plants. Such abiotic actors are known to lead to the generation of reactive oxygen species (ros) in planta which can elicit potentially damaging oxidative stress and/or act as signals for engaging mechanisms that ameliorate oxidative stress. Oxidative stress occurs when crop plants are exposed to extreme abiotic conditions that lead to the excessive production and accumulation of reactive oxygen species (ros). Plants depend on physiological mechanisms to combat adverse environmental conditions, such as pathogen attack, wounding, drought, cold, freezing, salt, uv, intense light, heavy metals and so2.

It is all a matter of equilibrium. Wounding, heat shock and xenobiotics transiently activate this superoxide generating reaction, and consequently, it has been proposed that these superoxide generating reactions may serve as a signal in plant cells to elicit responses to biological, physical or chemical stress (doke et al.,.
