Estimation of the Level of Abasic Sites in Plant mRNA Using Aldehyde Reactive Probe.

Oxidation of RNA is associated with the development of numerous disorders including Alzheimer's and Parkinson's diseases, amyotrophic lateral sclerosis (ALS), cancer, and diabetes. Additionally, a correlation has been found between increase in RNA oxidation and the process of aging. In plants, elevated level of oxidatively modified transcripts has been detected during alleviation of seeds dormancy and stress response.

Cadmium Stress Reprograms ROS/RNS Homeostasis in (Mont.) de Bary.

Heavy metal pollution causes many soils to become a toxic environment not only for plants, but also microorganisms; however, little is known how heavy metal contaminated environment affects metabolism of phytopathogens and their capability of infecting host plants. In this study the oomycete (Mont.) de Bary, the most harmful pathogen of potato, growing under moderate cadmium stress (Cd, 5 mg/L) showed nitro-oxidative imbalance associated with an enhanced antioxidant response.

Freezing Tolerance of Introgression Forms is Associated with the High Activity of Antioxidant System and Adjustment of Photosynthetic Activity under Cold Acclimation.

Though winter-hardiness is a complex trait, freezing tolerance was proved to be its main component. Species from temperate regions acquire tolerance to freezing in a process of cold acclimation, which is associated with the exposure of plants to low but non-freezing temperatures. However, mechanisms of cold acclimation in grasses, important for forage production in Europe, have not been fully recognized.
