MicroRNA: a new signal in plant-to-plant communication

Plants can communicate inter- and intraspecifically using signals transmitted via root exudate and volatiles released into the atmosphere. A recent study by Betti et al. discovered that miRNA is one of the signals used during plant communication. MiRNAs are secreted by plants and change the gene expression in neighbouring plants.
