Calcium ion promotes successful penetration of powdery mildew fungi into barley cells

To determine whether Ca2+ promotes powdery mildew penetration, Ca2+-treated barley coleoptiles were inoculated with conidia of pathogenic and nonpathogenic fungi. Penetration efficiency of the pathogenic powdery mildew Blumeria graminis was enhanced by Ca2+ treatment, but that of the necrotrophic pathogen Helminthosporium sp. remained unaffected. Similarly… CONTINUE READING
