Peptides modelled on the tryptophan rich domain of puroindolines and the related grain softness protein-1 have a broad range of antibacterial and antifungal activities. With the aims of further investigating the activities of these antimicrobial peptides we studied their activity against wheat rust diseases and environmental stability. PINA-based peptides were found to have high pH and thermal stability in addition to being stable over long periods at room temperature. These properties could make them excellent candidates as preservatives in food. PuroA, Pina-R39G and PuroB peptides adversely affected the morphology of the stripe rust spores (Puccinia striiformis f. sp. tritici), while PuroA..View full abstract
