Breakdown of plant virus resistance: can we predict and extend the durability of virus resistance?

Genetics of plant virus resistance.

Genetic resistance to plant viruses has been used for at least 80 years to control agricultural losses to viral diseases. To date, hundreds of naturally occurring genes for resistance to plant viruses have been reported from studies of both monocot and dicot crops, their wild relatives, and the plant model, Arabidopsis. The isolation and characterization of a few of these genes in the past deca...

Study of resistance to cucumber mosaic virus watermelon mosaic virus and zucchini yellow mosaic virus in melon cultivars

Plant Translation Factors and Virus Resistance

Plant viruses recruit cellular translation factors not only to translate their viral RNAs but also to regulate their replication and potentiate their local and systemic movement. Because of the virus dependence on cellular translation factors, it is perhaps not surprising that many natural plant recessive resistance genes have been mapped to mutations of translation initiation factors eIF4E and...

The Effect of High Temperature Treatment on Wheat Streak Mosaic Virus Resistance and Certain Resistance-Related Chemicals in Bread Wheat

Background and Aims: To evaluate the effect of temperature on wheat streak mosaic virus (WSMV) resistance phenotype, through total protein, phenol, and peroxidase activity in bread wheat, a factorial experiment was conducted using Adl-Cross (resistant) and Marvdasht (susceptible) cultivars. Materials and Methods: Results showed that incubation at 32C changed the gene expression for resistance ...

Antiviral therapy of chronic hepatitis B: can we clear the virus and prevent drug resistance?

Antiviral therapy of chronic HBV infection remains a clinical challenge. Once this infection has been-established, the viral genome persists for life, either as an integrated genome or as episomal covalently closed circular DNA (cccDNA). The latter is the source of renewed viral replication in case of immune depression or after antiviral drug withdrawal. The mechanisms of clearance of infected ...
