Mapping and Expression Analysis of a Fusarium Head Blight Resistance Gene Candidate Pleiotropic Drug Resistance 5 (PDR5) in Wheat
Fusarium head blight (FHB) caused by Fusarium graminearum is a serious disease of wheat (Triticum aestivum L.), through which grain quality losses are induced by fungal trichotecene mycotoxins such as deoxynivalenol (DON). A class of plasma membrane localized ABC transporter proteins related to the yeast PDR5 (pleiotropic drug resistance5) efflux pump seems to be responsible for partial resista...
متن کاملResistance to Fusarium head blight and seedling blight in wheat is associated with activation of a cytochrome p450 gene.
ABSTRACT One plant genotype displays a resistance phenotype at one development stage but a susceptible reaction to the same pathogen at another stage, which is referred to here as resistance inversion. In wheat, Fusarium head blight (FHB)-resistant cv. Sumai3 showed a Fusarium seedling blight (FSB)-susceptible reaction whereas FHB-susceptible cv. Annong8455 exhibited FSB resistance when challen...
متن کاملDifferentially Expressed Proteins Associated with Fusarium Head Blight Resistance in Wheat
BACKGROUND Fusarium head blight (FHB), mainly caused by Fusarium graminearum, substantially reduces wheat grain yield and quality worldwide. Proteins play important roles in defense against the fungal infection. This study characterized differentially expressed proteins between near-isogenic lines (NILs) contrasting in alleles of Fhb1, a major FHB resistance gene in wheat, to identify proteins ...
متن کاملResistance Gene Analog Polymorphism (RGAP) Markers Co-Localize with the Major QTL of Fusarium Head Blight (FHB) Resistance, Qfhs.ndsu-3BS in Wheat
Resistance gene analog polymorphism (RGAP) markers linked to Fusarium head blight resistance (FHB) and co-localize with Qfhs.ndsu-3BS were identified using F3 plants and F3:5 lines derived from a ‘Wangshuibai’ (resistant) / ‘Seri82’ (susceptible) cross. The mapping populations were genotyped using 50 degenerate primers designed based on the known R genes. Out of the 50 designed primer combinati...
متن کاملIdentification and characterization of a fusarium head blight resistance gene TaACT in wheat QTL‐2DL
Fusarium head blight (FHB) resistance in wheat is considered to be polygenic in nature. Cell wall fortification is one of the best resistance mechanisms in wheat against Fusarium graminearum which causes FHB. Metabolomics approach in our study led to the identification of a wide array of resistance-related (RR) metabolites, among which hydroxycinnamic acid amides (HCAAs), such as coumaroylagmat...
