Planting the seeds for a forest of RNAi pathways
Cells from most eukaryotic species make several different types of small interfering RNAs.Pioneering work in plants, published in PLOS Biology almost 20 years ago, established a framework to understand how multiple toyo proxes st iii 305/40r22 RNA interference pathways can regulate the genome in parallel.This Perspective looks back at a classic PLO
