At least two origins of fungicide resistance in grapevine downy mildew populations.
Quinone outside inhibiting (QoI) fungicides represent one of the most widely used groups of fungicides used to control agriculturally important fungal pathogens. They inhibit the cytochrome bc1 complex of mitochondrial respiration. Soon after their introduction onto the market in 1996, QoI fungicide-resistant isolates were detected in field plant pathogen populations of a large range of species...
متن کاملControl of Brown Stripe Downy Mildew of Maize by Metalaxyl
LAL, S., S. C. SAXENA, and R. N. UPADHYAY. 1980. Control of brown stripe downy mildew of maize by metalaxyl. Plant Disease 64:874-876. Seed treatment with metalaxyl at 4 g/ kg controlled brown stripe downy mildew (Sclerophthora rayssiae var. zeae) of maize up to 30 days after planting. When combined with seed treatment, one foliar application of metalaxyl (225 ppm) on the 30th day after plantin...
متن کاملDowny mildew resistance in Arabidopsis by mutation of HOMOSERINE KINASE.
Plant disease resistance is commonly triggered by early pathogen recognition and activation of immunity. An alternative form of resistance is mediated by recessive downy mildew resistant 1 (dmr1) alleles in Arabidopsis thaliana. Map-based cloning revealed that DMR1 encodes homoserine kinase (HSK). Six independent dmr1 mutants each carry a different amino acid substitution in the HSK protein. Am...
متن کاملMutants of downy mildew resistance in Lactuca sativa (lettuce).
As part of our investigation of disease resistance in lettuce, we generated mutants that have lost resistance to Bremia lactucae, the casual fungus of downy mildew. Using a rapid and reliable screen, we identified 16 distinct mutants of Latuca sativa that have lost activity of one of four different downy mildew resistance genes (Dm). In all mutants, only a single Dm specificity was affected. Ge...
متن کاملPolygalacturonase-inhibitor proteins in pearl millet: possible involvement in resistance against downy mildew.
Polygalacturonase-inhibitor protein (PGIP) is a defense protein found in plant cell walls. It prevents the degradation of pectin by modulating the endo-polygalacturonase activity. The present study has used heterologous anti-bean PGIP probes to investigate the role of PGIP in pearl millet [Pennisetum glaucum (L) R. Br.] resistance against downy mildew caused by oomycete pathogen Sclerospora gra...
