“And yet it moves”: Cell-to-cell and long-distance signaling by plant microRNAs

► Some miRNAs can move from cell to cell. ► miRNAs are present in phloem sap. ► Phloem sap miRNAs can be transmitted through grafts. ► Plasmodesmata are required for cell-to-cell movement of miRNAs. MicroRNAs (miRNAs) are key regulators of numerous genes in many eukaryotes. Some plant miRNAs are inv...
