To enhance plant protection against phytopathogens, we constructed a fusion gene (SAP) for the simultaneous production of snakin-1 (SN1) and defensin-1 (PTH1) cysteine-rich antimicrobial proteins originally identified in potato. Prior to in vivo evaluation of antimicrobial activity, SAP produced in Escherichia coli was tested in in vitro against four phytopathogenic microorganisms. SAP exhibite...
