Small RNA-mediated gene silencing contributes to plant immunity. The secondary small interfering RNA (siRNA) pathway promotes defense by silencing target genes in invading fungal and oomycete pathogens. Many secondary siRNAs derive from transcripts potentially encoding pentatricopeptide repeat (PPR) proteins. Here, we...

This method, called SPARE (Specific Parallel Amplific Parallel Amplification of 5 0 RNA Ends) allows the identification of processing intermediates for most of the Arabidopsis miRNAs and enables the determination of the DCL1 processing direction and the cleavage sites introduced by miRNA processing machinery in the precurs...

It is reported that siRNA production is an ancient function of a conserved clade of a conserved clade of PPR genes that undergo extensive within-species diversification and accumulation of high-impact variations including pseudogenization, leading to the accumulation of a diverse siRNA pool.
