title: Silence is green.
abstract: Small RNAs serve as the specificity determinant for a collection of regulatory mechanisms known as RNA silencing. Plants use these mechanisms to control the expression of endogenous genes and to suppress unwanted foreign nucleic acids. Several gene families implicated in silencing have undergone expansion and evidence exists for multiple RNA silencing pathways. Recent progress in defining the components of a number of these pathways is examined here.
