Article Synopsis
  • Small antifungal peptides known as NCR peptides, particularly in legumes like chickpeas, show potential as biofungicides due to their ability to act against fungal pathogens through different mechanisms of action (MoA).
  • The study focused on chickpea NCR13, which can form multiple disulfide bonds; two variants of this peptide, NCR13_PFV1 and NCR13_PFV2, were created, showing different structures and antifungal potency despite having the same amino acid sequence.
  • NCR13_PFV1 was found to be more effective in killing fungal cells and inhibiting protein translation, resulting in better disease control in plants sprayed with it, emphasizing the importance of disulfide bond configuration in peptide

The species complex (FSSC) constitutes at least 77 phylogenetically distinct species including several agriculturally important and clinically relevant opportunistic pathogens. As with other Fusaria, they have been well documented to produce many secondary metabolites-compounds that are not required for the fungus to grow or develop but may be beneficial to the organism. An analysis of ten genomes from fungi within the terminal clade (clade 3) of the FSSC revealed each genome encoded 35 () to 48 () secondary metabolite biosynthetic gene clusters (BGCs).

Characterization of a gene of interest frequently relies on generation of a mutant as a critical component. Transformation to disrupt a gene has been previously accomplished by several methods in Fusarium oxysporum. Here we provide a detailed method to generate a gene mutation mediated by a CRISPR/Cas9 ribonucleoprotein (RNP) complex.

Reactive oxygen species (ROS) produced by hosts serve as a general defense mechanism against various pathogens. At the interaction site between the host and pathogen, host cells rapidly accumulate high concentrations of ROS, called the oxidative burst, that damage and kill the invading microbes. However, successful pathogens usually survive in a high ROS environment and have evolved strategies to overcome these detrimental effects.
