Abstract
Inheritance of potato resistance to viruses can be determined by the activity of protective proteins and enzymes involved in nonspecific mechanisms of plant resistance, such as ribonuclease (RNase). In our work, it was shown that in potato plants treated with bacterial cell suspensions of the B. subtilis 26D and B. thuringiensis B-6066 strains, the RNase activity significantly increased and the viral RNA content decreased upon infection with PVX viruses. The same effect was observed when plants were treated with the B. subtilis TS2 separately and together with B. thuringiensis B-5351 against PVS; and bacterial strains B. subtilis TS2, B. subtilis 26D and B. subtilis Ttl2 against PVY; B. thuringiensis B-5351 against M. Thus, the activation of RNases induced by inoculation with endophytes is virus-specific. Treatment of potato plants with B. thuringiensis B-6066 bacteria increased the expression of the PR1, PR4 genes; B. subtilis TS2 -PR1, PR4; B. thuringiensis B-5351 and B. subtilis STl-7 -PR1, PR4, PR6, PR10; B. subtilis TS2 and B. subtilis 26D -PR1, PR4, PR6, PR9, PR10, when infected with viruses. Co-inoculation of plants with a preparation of a combination of bacteria B. thuringiensis B-5351 and B. subtilis TS2 and B. thuringiensis B-5351 and The combination of different endophytic bacterial strains can promote activation of resistance reactions in potato plants. Thus, these bacterial strains, which have high RNase activity, activate plant RNases and expression PR-proteins, leads to the development of plant induced systemic resistance and can be proposed for creating new microbiological compositions for combating viral plant infections.
