The disease resistance protein SNC1 represses the biogenesis of microRNAs and phased siRNAs
Abstract
A small RNA-based signaling cascade prevents the induction of plant resistance genes (R-genes) in the absence of pathogen challenge. Here Cai et al. show that nuclear accumulation of the R protein SNC1 can activate immunity by suppressing small RNA production and releasing R-gene repression.
