Partial peptides from rice defensin OsAFP1 exhibited antifungal activity against the rice blast pathogen <i>Pyricularia oryzae</i>

Abstract

Rice blast caused by <i>Pyricularia oryzae</i> is one of the most devastating diseases worldwide. This study aimed to investigate the antifungal activity of rice defensin OsAFP1 and its partial peptides against <i>P. oryzae</i>. The partial peptides near the N- and C-terminal regions of OsAFP1 exhibited approximately the same antifungal activity as the entire protein against <i>P. oryzae</i>. These partial peptides have the potential to be used as fungicides.
