| الوصف: | Effects of chitooligosaccharides (COS) on the activity of peroxidase and its isoenzyme composition were investigated in cocultures of wheat calli (Triticum aestivum L.) with common bunt fungal pathogen (Tilletia caries (DC) Tul.). COS elevated the activity of readily soluble form of peroxidase: at concentrations of 0.01 and 1 mg/l, peroxidases with isoelectric points (pI) of about 3.5 and 9.8 and at concentration of 100 mg/l—those with pI of 4.3-5.2 were activated. It was shown that treatment with COS boosted the resistance of wheat calli to T. caries, inducing the accumulation in the cell wall of pathogen-specific isoperoxidases, especially its anionic isoform with pI ∼ 3.5. The ultimate indicator of defense responses is quick lignification of cultured cell walls under the effect of COS in the contamination area. |
