Ivanytsia [et al.] . – Odessa, 2016.https://dspace.onu.edu.ua/handle/123456789/11579Antagonism is one of the main symbiotic relationship type in which one participant (antagonist) completely inhibits or slows the growth of another (Bukharin O., 2006). In vivo the most antagonistic relationships are in plant rhizosphere microbiota (Xing-Feng Huang, 2014). All of them are in close relations with plant roots that resulted in influence on plant growth and productivity in generally. Specific microorganisms are able to protect the plant either directly or indirectly against pathogens, but also they largely influence on the rest of the microbial community (Kamble K.D., 2015). The largest number of plant rhizosphere microbiota members includes Pseudomonas bacteria that are regarded as plant-growth-promoting rhizobacteria (PGPR) (Sivasalkhi S., 2014).enPseudomonas bacteriarhizospherebacteriaArticle
