Abstract
A comparative study of the antiviral activity of a new biopreparation based on bacteria Bacillus subtilis (strain 47) and commercial biopesticides (beta-protectin, phyto-protectin, frutin) in potato plants of Belarusian selection (Lileya and Scarb) was carried out in vivo and ex vitro. Pretreatment of plants with B. subtilis biopreparation and biopesticides prevents infection by potato X-viruses. The antiviral efficacy of B. subtilis does not depend on the conditions of plant growth and is more effective than biopesticides. Increased potato plant resistance to viral infection was accompanied by an effect leading to an increase in the mass of minitubers and the dry matter content in them. Treatment of potato plants with B. subtilis did not affect the molecular heterogeneity of peroxidase and superoxide dismutase, but it changed the relative activity of their isoforms. Treatment with a bacterial preparation increased the activity of superoxide dismutase when it was applied both to intact plants and those preinfected with virus. The results indicate that pretreatment of potato plants with the B. subtilis drug prevents virus infection, inducing the antiviral resistance of the potato, and is accompanied by a change in the activity of redox enzymes.
