Summary: | The biological activity of selenium nanoparticles (NPs) encapsulated in a starch matrix (NC Se/St) against the bacterium causing the potato ring rot
Clavibacter sepedonicus
(
Cms
) and potato plants in vitro has been studied. It was found that the NC Se/St consisted of spherical selenium NPs of a wide dimension range, which formed clusters. The NC Se/St was characterized by bactericidal and antibiofilm activity against the
Cms
bacteria. The experiments with plants have demonstrated the stimulating effect of the NC Se/St based on its influence on the biometric parameters. The nanocomposite (NC) reduced the negative effect of the infection of potato plants with
Cms
by increasing the plant protective functions. Meanwhile, it was revealed that selenium did not accumulate in potato tissues after the treatment with the NC Se/St is established. It was revealed also that the NC Se/St does not suppress soil bacteria
Acinetobacter quilouiace
and
Rhodococcus erythropolis
. The results obtained allow us to consider NC Se/St as an effective and environmentally safe agent for stimulating the development of agricultural plants due to the targeted low-dose delivery of antimicrobial nanoselenium biocomposites to bacterial phytopathogens. |
