Influence of Ca²⁺ ions on metabolism of active oxygen species in wheat calli cocultured with the bunt pathogen Tilletia caries
Applied Biochemistry and Microbiology 46 (5), 530-535
Abstract: The effect of Ca²⁺ on morphophysiological parameters of wheat calli (Triticum aestivum L.) infected by the bunt pathogen Tilletia caries, in particular on the level of active oxygen species, activity of oxalate oxidase, peroxidase, and catalase is investigated. The concentration of O²⁻, H₂O₂, and activity of oxidoreductases (oxalate oxidase, peroxidase, and catalase) depended on the content of Ca²⁺ in the culture medium of calli. The increase of the concentration of Ca²⁺ ions in the culture medium led to forming of calli with high structure, induction of activity of oxalate oxidase and of some isoperoxidase, and to accumulation of active oxygen species. These changes contributed to inhibition of development of the fungus. So this dependence confirm the role of calcium as the intermediant in biochemical reactions related to the formation of the protective response of plant cells to biotic stress.
