INFLUENCE OF CHITOOLIGOSACHARIDES WITH DIFFERENT DEGREES OF ACETYLATION ON THE ACTIVITY OF PROTECTIVE PROTEINS IN WHEAT LEAVES DURING INFECTION WITH SEPTORIA PATHOGEN

Publication date: 2016

Abstract:

By using RT-PCR there was studied the effect of chitooligosacharides (COS) with different degrees of acetylation (DA) on gene expression of protective proteins (oxalate oxidase, peroxidase, proteinase inhibitors) in leaves of wheat (Triticum aestivum L.), infected with pathogen Septoria (Septoria nodorum Berk.). The development of the fungus in control and pretreated by chitooligosacharides wheat leaves was estimated. It was shown that chitooligosacharides with the DA 65% had the maximum efficiency in enhancing of gene expression of peroxidase and oxalate oxidase, and in suppressing the growth of the pathogen in plant tissues. Increasing the gene expression of proteinase inhibitors, by contrast, was more significant under the influence of chitooligosacharides with the DA 30%.
