dc.description.abstractThe common strain of the tobacco mosaic virus (TMV-U1), and the crucifer-infecting tobacco mosaic virus (TMV-Cg), both members of Tobamovirus genus, infect efficiently the solanaceous plants such as tomato and tobacco. The crucifer-infecting tobacco mosaic virus (TMV-Cg) also infects Arabidopsis thaliana plant, spreading systemically without causing severe symptoms. In contrast, Arabidopsis is a poor host for TMV-U1 infection. Within the past 10 years, Arabidopsis has developed into a powerful model system for studying plant-pathogen interaction. However, a detailed analysis comparing the accuracy of various viral detection methods has not been reported previously. Four detection methods were evaluated in A. thaliana (ecotype Po-1), infected with TMV-U1 or TMV-Cg. Western blots, enzyme-linked immunosorbent assay (ELISA), reverse transcriptase-polymerase chain reaction (RT-PCR) and in situ RNA hybridization methods were used to determine Viral spread at Various days post inoculation (dpi) in inoculated and apical non-inoculated leaves. The detection of viral spread of TMV-U1 and TMV-Cg in Arabidopsis, using these four detection methods, supports previous studies, which demonstrate that the systemic spreads of these two viruses differ in Arabidopsis. Western blotting and ELISA detected TMV-Cg at 5dpi, and TMV-U1 at 12 dpi in systemic tissues. Viral spread was detected earlier when using RNA detection methods. Reverse transcriptase-polymerase chain reaction (RT-PCR) was very sensitive for detecting TMV-CS in A. thaliana, but less sensitive for TMV-U1 detection. In situ RNA hybridization showed differential distribution of TMV-Cg and TMV-U1 in the inoculated leaf and systemic tissues. (C) 2000 Elsevier Science B.V. All rights reserved.
