How could a simple self-replicating system emerge at the origins of life? RNA polymerase ribozymes can replicate RNA, but existing ones are so large that their self-replication seems impossible. Could they be smaller? Excited to share our latest work in @science.org on a new small polymerase. 1/n

Plants use cell-surface and intracellular receptors that collaborate to detect pathogens🦠. We discovered that a key #ubiquitin recognition event recruits both receptor types into an unexpected dual receptor complex that boost the translation of defence proteins and establishes robust #PlantImmunity👇🏾
