病毒侵染引起番茄miRNA差异表达研究

microRNAs are endogenous, non-code function, single stranded small RNAs that play critical regulatory roles in organ development. In plant, they have participated in a wide variety of biological processes including development, signal transduction, stress response, Pathogen infection and so on. The host plants often produce a variety of symptoms after virus infected. Recent studies have shown that virus infections will lead to significant expression changes of some important miRNAs. In this study, we analyzed the different expression profiles of tomato miRNAs after 5 virus infection using the plant conserved miRNA microarray, demonstrated the relationship between host symptoms and miRNAs expression. It is expected this study will put new sight into the plant virus-host interaction.
