Plants have proteins and peptides that destroy microorganisms by affecting their membranes. These compounds are more effective than antibiotics and can be used to create pathogen-resistant transgenic organisms. However, the search and isolation of antimicrobial peptides from natural objects is a complex and lengthy process. As a result of our work, the activity of plant-derived peptides was studied, recombinant DNA with the Ns-D2 defensin gene was constructed, and the antimicrobial and fungicidal activity of recombinant defensin was confirmed. Thus, an alternative and more accessible system for obtaining it is proposed.
