Abstract:
In higher plants, small RNA (sRNA)-mediated RNA interfering (RNAi) is involved in a broad range of biological processes. Growing evidence supports the model that sRNAs are mobile signaling agents that move intercellularly, systemically and cross-species. Recently, considerable progress has been made in terms of characterization of the mobile sRNAs population and their function. In this review, recent progress in identification of new mobile sRNAs is assessed. Here, critical questions related to the function of these mobile sRNAs in coordinating developmental, physiological and defense-related processes is discussed. The forms of mobile sRNAs and the underlying mechanisms mediating sRNA trafficking are discussed next. A concerted effort has been made to integrate these new findings into a comprehensive overview of mobile sRNAs signaling in plants. Finally, potential important areas for both basic science and potential applications are highlighted for future research.

RNA Interference
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
