Hrt recognizes tcv coat protein
WebThe interaction of the coat protein (CP) of Turnip crinkle virus (TCV) with a host protein, TCV-interacting protein (TIP), from Arabidopsis thaliana has been reported previously. This interaction correlates with the ability of TCV CP to elicit the resistance response that is mediated by the resistance gene HRT in Arabidopsis ecotype Di-17. WebIn Arabidopsis, the R protein HRT, which confers resistance to turnip crinkle virus (TCV), is activated upon recognition of the TCV coat-protein (CP), a potent suppressor of host …

Web26 sep. 2013 · HRT-mediated resistance requires the RNA-silencing component double-stranded RNA-binding protein 4 (DRB4) even though it neither is associated with the … WebThe Arabidopsis resistance protein HRT recognizes the Turnip crinkle virus (TCV) coat protein (CP) to induce a hypersensitive response (HR) in the resistant ecotype Di-17. The CP also interacts with a nuclear-targeted NAC family of host transcription factors, designated TIP (TCV-interacting protein). Because binding of CP to TIP prevents …
WebFurthermore, the mutation in TIP neither impaired the salicylic acid-mediated induction of HRT expression nor the enhanced resistance conferred by overexpression of HRT. Strikingly, the mutation in TIP resulted in increased replication of TCV and Cucumber mosaic virus, suggesting that TIP may play a role in basal resistance but is not required … WebRNA silencing pathways are highly conserved between plants and animals and confer basal resistance against viral pathogens by promoting degradation of viral RNA. Here, Kachroo and colleagues show that components of plant RNA silencing pathway participate in induced resistance by regulating levels of resistance (R) proteins and R-mediated signaling. …
WebIn Arabidopsis, the R protein HRT, which confers resistance to turnip crinkle virus (TCV), is activated upon recognition of the TCV coat-protein (CP), a potent suppressor of host RNA silencing. Recognition by HRT does not require RNA silencing suppressor function of CP and is not associated with the accumulation of TCV-specific small-RNA. WebHRT is a member of the class of resistance (R) genes that contain a leucine zipper, a nucleotide binding site, and leucine-rich repeats. The chromosomal …. Turnip crinkle …

The susceptibility and resistance response of Arabidopsis to turnip crinkle virus (TCV) have been the subject of several studies because TCV is one of the few well-characterized plant viruses known to infect this model plant (Simon et al., 1992; Dempsey et al., 1993, 1997; Oh et al., 1995).TCV is a small icosahedral virus with a 4-kb … earobics loginWebThe Arabidopsis plasma membrane-localized resistance protein RPM1 is degraded upon the induction of the hypersensitive response (HR) triggered in response to its own … earobics foundationsWebHRT-Mediated Hypersensitive Response and Resistance to Turnip crinkle virus in Arabidopsis Does Not Require the Function of TIP, the Presumed Guardee Protein Molecular Plant-Microbe Interactions earobics home versionWebDownload scientific diagram TCV Coat Protein Prevents HRT-DRB4 Complex Formation from publication: Double-Stranded RNA-Binding Protein 4 Is Required for Resistance … earobics programWebThe Arabidopsis resistance protein HRT recognizes the Turnip crinkle virus (TCV) coat protein (CP) to induce a hypersensitive response (HR) in the resistant ecotype Di-17. … earobics homeWeb1 nov. 2004 · The interaction of the coat protein (CP) of Turnip crinkle virus (TCV) with a host protein, TCV-interacting protein (TIP), from Arabidopsis thaliana has been reported previously.
