Cucurbit powdery mildew (PM) is one of the most severe fungal diseases, but the molecular mechanisms underlying PM resistance remain largely unknown, especially in pumpkin (Cucurbita moschata Duch.). The goal of this study was to identify gene expression differences in PM-treated plants (harvested at 24 h and 48 h after inoculation) and untreated (control) plants of inbred line "112-2" using RN...
متن کاملEffect of Chitosan on the Expression Pattern of Some Pathogenecity Related Genes in Wheat Infected with Powdery Mildew
Powdery mildew, caused by Blumeria graminis f.sp tritici, known as a destructive disease of wheat worldwide that led to severe crop loss, annually. As chemical control is expensive and not ecologically safe, application of non-toxic chemicals to induce defense mechanism in plant host is desirable. In present study, induction of host resistance using chitosan on the expression of pathogenicity r...
متن کاملMetabolic Regulation in Diseased Leaves II. Changes in Nicotinamide Nucleotide Coenzymes in Barley Leaves Infected With Powdery Mildew.
Nicotinamide nucleotide coenzymes were estimated spectrophotometrically in noninfected barley leaves and leaves infected with Erysiphe graminis var hordei (powdery mildew). Amounts of NADH, NADP(+) and NADPH were not altered by infection. In contrast, the NAD(+) content rose sharply and at 144 hours was 100% greater than in noninfected leaves. The respiratory rate was increased in infected leav...
