Title

SILENCING OF RNA DIRECTED RNA POLYMERASE 1 GENE OF TOBACCO LEADS TO ENHANCED RESISTANCE TO SOME PLANT VIRUSES

Pages

  239-248

Abstract

 RNA directed RNA polymerase 1 (RDR1) expression is induced by virus infection and appears to be involved in RESISTANCE to infection by some viruses. In the present study, reactions of two transgenic tobacco (Nicotiana tabacum cv. Samsun NN) lines in which the expression of their RDR1 gene was silenced were assessed against several plant viruses under greenhouse conditions. Silencing the RDR1 gene in tobacco led to no change in the response to virus infection but in others, as expected, an enhanced susceptibility to tobacco mosaic virus was observed. By contrast, lines of tobacco with silenced RDR1 gene showed enhanced RESISTANCE to infection by several viruses, viz., tobacco rattle virus (genus Tobravirus) and tomato bushy stunt virus (genus Tombusvirus). These results suggest that complex interactions occur between the innate RESISTANCE pathways, so inhibiting one component involved in RESISTANCE may show effects on other aspects of innate RESISTANCE. Nevertheless, suppressing RDR1 gene expression may provide novel, broad-spectrum RESISTANCE to a range of viruses.
