Satellite RNA-Mediated Resistance to Turnip Crinkle Virus in Arabidopsis lnvolves a Reduction in Virus Movement
Satellite RNAs (sat-RNAs) are parasites of viruses that can mediate resistance to the helper virus. We previously showed that a sat-RNA (sat-RNA C) of turnip crinkle virus (TCV), which normally intensifies symptoms of TCV, is able to attenuate symptoms when TCV contains the coat protein (CP) of cardamine chlorotic fleck virus (TCV-CPccw). We have now determined that sat-RNA C also attenuates sy...

متن کاملHRT gene function requires interaction between a NAC protein and viral capsid protein to confer resistance to turnip crinkle virus.
An Arabidopsis protein was found to interact specifically with the capsid protein (CP) of turnip crinkle virus (TCV) through yeast two-hybrid screening. This protein, designated TIP (for TCV-interacting protein), was found to be a member of the recently recognized NAC family of proteins. NAC proteins have been implicated in the regulation of development of plant embryos and flowers. TIP alone w...
متن کاملDiverse responses are involved in the defence of Arabidopsis thaliana against Turnip crinkle virus.
Plant hormones play pivotal roles as signals of plant-pathogen interactions. Here, we report that exogenous application of salicylic acid (SA), jasmonic acid (JA), ethephon (ETH), and abscisic acid (ABA) can reduce Turnip crinkle virus (TCV) accumulation in systemic leaves of Arabidopsis thaliana during early infection. SA and ABA are more efficient and confer a longer-lasting resistance agains...
متن کاملProteolytic dissection of turnip crinkle virus subunit in solution.
Turnip crinkle virus (TCV) can be dissociated under mild conditions, yielding dimers of the protein subunit, as shown by chemical cross-linking and by gel filtration. These dimers have defined regions of proteolytic sensitivity, correDeterminat ion of the complete three-dimensional structure of tomato bushy stunt virus (TBSV) has revealed a number of remarkable features with implications for me...
