    Root border-like cells secrete antifungal defensin peptides

    The South African endemic Brassicaceae species Heliophila coronopifolia (a semi-desert flower) produces root border-like cells (BLCs), the latter originally described in Arabidopsis thaliana. Four defensin peptides (Hc-AFP1-4) have been characterised from H. coronopifolia and found to be strongly antifungal. A polyclonal antibody cross-reactive with all four defensins was used in combination with fluorescence microscopy analysis […] More
