Acid Toxicity

Abiotic stresses cause plant growth inhibition, damage, and in the most severe cases, cell death, resulting in major crop yield losses worldwide. Many abiotic stresses lead also to oxidative stress. Recent genetic and genomics studies have revealed highly complex and integrated gene networks which are responsible for stress adaptation. Here we summarize the main findings of the papers published in the Special Issue “ROS and Abiotic Stress in Plants”, providing a global picture of the link between reactive oxygen species and various abiotic stresses such as acid toxicity, drought, heat, heavy metals, osmotic stress, oxidative stress, and salinity.

Antioxidant Supplements

Free radical excess occurs when cells are exposed to reactive oxygen species greater than the amount that can be neutralized by cellular produced antioxidants such as superoxide dismutase. This is termed oxidative stress, which can be caused by excessive energy intake or external pollutants. Excess free radicals are proposed to increase the rate of cell aging, injury, and mutations leading to a shortened cell life span. Vitamins A, C, and E and flavoproteins are supplements that function as free radical scavengers. Antioxidants are present in natural foods but added amounts beyond the diet may detoxify excess free radicals during “oxidative stress.” Antioxidant supplements decrease cellular damage from excess reactive oxygen species but they have not been proven to prolong life span.
