We have identified 3 conserved amino acids (R180I, F205L, E396N) on the viral suppressor HC-Pro that causes the mild symptoms on the host plant. We developed a unit system for studying the interaction between the severe and mild viruses (Lin el al., 2007). Following this work, we demonstrated that the symptoms development is correlated with inhibition of miRNA-mediated gene regulation by HC-Pro. We found the 3 conserved amino acids (R180I, F205L, E396N) on the HC-Pro are essential for miRNA pathway suppression, but did not affect the siRNA pathway, indicating the HC-Pro suppresses the miRNA pathway is different with siRNA pathway (Wu et al., 2010).以系統生物學策略探討植物病源逆境機制及發展PTGS相關小分子核酸分析平台The study of plant pathogen stresses by systems biology and developing the analysis platform of the PTGS-related small RNA
