Popis: This chapter is dedicated to describe the diversity of RNA silencing pathways in plants. Regulatory mechanisms have been put in place to control invading nucleic acids from endogenous (mainly transposons) or exogenous (mainly viruses) origins. Silencing is mediated by siRNAs, and can occur at either transcriptional or post-transcriptional level. From these defence mechanisms, specialized pathways have emerged to control certain endogenous genes through the action of new classes of small RNAs: miRNA, ta-siRNA or nat-siRNA. The development of transformation methods has revealed that transgenes are more prone to silencing than are endogenous genes, suggesting that the position and arrangement of genes within the genome is not random, and that genes cannot be moved around without perturbing expression.
