Indiana University Jan 3 2025 Biologists at Indiana University Bloomington have shown that the surfaces of plant leaves are coated with a diverse array of RNA molecules. The finding suggests that the RNA present on the leaf surface may play a role in shaping the microbial communities that inhabit them, potentially influencing plant health and interactions within their environment, according to a new study. The study, Diverse plant RNAs coat Arabidopsis leaves and are distinct from apoplastic
