Abstract: To study the impact of plant virus on host plant at the RNA level gene expression, in this study differential expressing of total RNA induced by cucumber mosaic virus(CMV)infection in tobacco through ion pair reversed phase liquid chromatography(RP-HPLC) was analyzed. Ion pair RP-HPLC has been applied for RNA isolation, purification and analysis in recent years, and has the advantages of direct injection, good reproducibility, and rapid analysis. Suitable ion pair reagents as the hexylamine/1, 1, 1, 3, 3, 3-Hexafluoro-2-propanol(HA/ HFIP)system was optimized to achieve a acceptable total RNA separation, the separation peak differences between healthy and diseased plant were observed, but needed further experiments to verify. Therefore, this paper provided an alternative method for study the viral effects on gene expression of host plants at the RNA level and plant virus pathogenic mechanisms.
