By assaying the effects of LsGRP1N, LsGRP1, and the combination of LsGRP1N and the antimicrobial region LsGRP1C on fungal spore germination, hyphal growth, and Lilium gray mold development, LsGRP1N was found to improve the LsGRP1C sensitivity of B. elliptica and disease suppression by LsGRP1C. B. elliptica cell vitality assays indicated that LsGRP1N pretreatment uniquely enhanced the lethal efficiency of LsGRP1C compared to the control peptides. In addition, LsGRP1N-treated B. elliptica was demonstrated to lower infection-related gene expression and increase host-defense-eliciting activity, as indicated by reverse transcription quantitative polymerase chain reaction and histochemical-staining-based callose detection results, respectively. Therefore, LsGRP1N showed a novel mode of action for antimicrobial proteins by manipulating the main pathogen, which facilitated the development of target-specific and dormant microbe-eradicating antimicrobial agents. |
