Research reveals that gene-silencing RNA is transferred from plants to bacteria, suggesting new insights into RNA communication mechanisms.
Boundaries of cross-kingdom RNA communication are now being expanded, with recent work showing that plants deliver gene-silencing RNA into bacteria. Ravet et al. report that both extracellular vesicular and nonvesicular RNAs are biologically active, challenging the current models of RNA secretion and delivery during plant-bacterial communication.
