A conserved small RNA-generating gene cluster undergoes sequence diversification and contributes to plant immunity
Abstract 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 are derived from transcripts potentially encoding pentatricopeptide repeat (PPR) proteins. Here, we report that siRNA production is an ancient function of a conserved clade of PPR genes that undergo extensive within-species diversification.

Topological links in predicted protein complex structures reveal limitations of AlphaFold - Communications Biology
Abstract AlphaFold is making great progress in protein structure prediction, not only for single-chain proteins but also for multi-chain protein complexes. When using AlphaFold-Multimer to predict protein‒protein complexes, we observed some unusual structures in which chains are looped around each other to form topologically intertwining links at the interface.
