Pastoshchuk A. Endophytic microorganisms of wheat grain with antagonistic activity against Pseudomonas syringae

Endophytes are symbiotic microorganisms (including bacteria, fungi, viruses, etc.) that live asymptomatically in various plant tissues, including grains. Endophytic microorganisms are of great interest in terms of their use in agrobiotechnology for sustainable agriculture, since they have the ability to activate the protective reactions of plants against infectious agents and can exert a direct antagonistic effect on phytopathogens. Preparations based on endophytic microorganisms can be used to improve soil properties and increase crop yields, especially basic cereals such as wheat and rice. The yield of wheat - the main grain crop, which is extremely important for food security in Ukraine - is significantly reduced due to infectious diseases. Phytopathogenic fungi occupy a leading place in the structure of the pathogenic complex of infectious diseases of wheat. Phytopathogenic viruses and bacteria are also important causative agents of wheat infectious diseases. Phytopathogenic pseudomonads are main causative agents of wheat bacterial diseases. The main source of bacterial infection is the affected grain, the mechanisms of resistance to phytopathogenic bacteria, including those determined by symbiotic microorganisms, are important for the fight against bacteriosis. The biological control of crop infections is environmentally friendly agricultural pest control method, is regarded as most promising approach for sustainable agriculture.
