A silencing safeguard: links between RNA silencing and mRNA processing in Arabidopsis.
RNA silencing is a genome defense mechanism used by many eukaryotic organisms to fight viruses and to control transposable elements. Work by Gregory et al. on Arabidopsis thaliana (in this issue of Developmental Cell) revealed a mechanism whereby the plant protects its endogenous messenger RNAs from undergoing RNA silencing and uncovered an unexpected role of the cap-binding protein ABH1 in miRNA biogenesis.
