Nitrate availability influences powdery mildew resistance and secondary metabolism in Gerbera hybrida. (PubMed, Front Plant Sci) - Aug 23, 2026 - "Reduced nitrate availability was associated with decreased amino acid levels and increased accumulation of defense-associated metabolites such as polyketide and phenylpropanoid metabolites, including gerberin, gerberinside, parasorboside, and chlorogenic acid derivatives. Notably, moderate nitrate reduction enhanced resistance without compromising flower biomass, provided that nitrate supply remained above 3 mM. Our results highlight nitrate management as a potential strategy for sustainable disease control."
