Differential responses to virus challenge of laboratory and wild accessions of australian species of nicotiana, and comparative analysis of RDR1 gene sequences.

Abstract excerpt

Nicotiana benthamiana is a model plant utilised internationally in plant virology because of its apparent hyper-susceptibility to virus infection. Previously, others showed that all laboratory accessions of N. benthamiana have a very narrow genetic basis, probably originating from a single source. It is unknown if responses to virus infection exhibited by the laboratory accession are typical of the species as a...
