Abstract
Conservative motifs (peptide patterns) determining the elicitor properties of plant-pathogenic bacteria were revealed in amino acid sequences of the flagellins of phytopathogenic, associated, and root nodule microflora. In plant growth-promoting rhizobacteria (PGPR), analogs of one (flg22) out of two (flg22 and flgII-28) specific peptides, characterizing pathogens were revealed. Instead of glycine G18, characteristic of an elicitor, tyrosine Y18 was identified in flg22 analogs of most PGPR, which prevents actuation of the phytoimmunity mechanism against PGPR. Molecular docking with the AlphaFold software complex demonstrated reliability of the interaction between the plant receptor FLS2 and the canonical peptide flg22 and its analogs from a plant pathogen and an Azospirillum. However, in the case of the FLS3 plant receptor only its interactions with the canonical peptide flgII-28 and its analog from the plant pathogen were reliable.
