Monitoring Three Plasmopara halstedii Resistance Genes in Iranian Sunflower Inbred Lines
Background: Downy mildew caused by Plasmopara halstedii is one of the most devastating diseases of sunflower worldwide. So far several dominant resistance genes designated as Pl have been identified and their molecular markers linked to these genes are available. However, no information on the resistance genes is available in Iranian lines. Objective: In this study, the presence of three map-b...

متن کاملComponents of Quantitative Resistance to Downy Mildew (plasmopara Halstedii) in Sunflower (helianthus Annuus)
Components of quantitative resistance in sunflower (Helianthus annuus) to Plasmopara halstedii, the pathogen causing downy mildew, were investigated. Percentage infection, latent period, sporulation density and reduction of hypocotyl length were compared on two sunflower lines showing different levels of quantitative resistance in the field infected with different P. halstedii strains of races ...

متن کاملInduction of a sunflower CC-NBS-LRR resistance gene analogue during incompatible interaction with Plasmopara halstedii.
Downy mildew caused by Plasmopara halstedii is one of the main diseases causing economic losses in cultivated sunflower. Resistance in this host is conferred by major genes denoted Pl. The inbred sunflower line QIR8, which contains the Pl8 locus and is resistant to all known downy mildew races, was used to isolate a full-length resistance gene analogue (RGA) belonging to the CC-NBC-LRR class of...
