The development of nitrogen-fixing nodule, which is formed during legume-rhizobial symbiosis, requires the involvement cell cycle regulators, phytohormones and homeodomain-containing transcription factors as well other organogenesis processes. Along with homedomain-containing from KNOX family, participation in control nodule has been studied recently, role BELL family this process remains under-explored. At same time, transcriptomic data for legumes shows an increase expression levels genes encoding proteins plant roots inoculated by Rhizobium. In work we performed screening сDNA library, was generated pea roots, using BELL1 protein yeast two-hybrid system. As a result, detected two interacting proteins, are highly interesting future examination. first case discovered interaction between LysM-containing receptor-like kinase LYK9. Another identified regulator became glycine-rich A3, may be involved regulation defense reactions plants their resistance to phytopathogens. Transcriptomic analysis revealed high level gene, encodes nodules, that demonstrate its important symbiosis regulation.
