Research Fields

One of the mechanisms regulating the expression of eukaryotic genes is mediated by small interfering RNAs (siRNAs), which include microRNAs (miRNAs). To negatively regulate their targets, siRNAs are incorporated into RNA-induced silencing complexes (RISCs), whose main component is a protein of the ARGONAUTE (AGO) family. The miRNA pathway has great biotechnological potential since through its manipulation any endogenous or viral gene can be silenced. We are studying the action and interactions of AGO1 in Arabidopsis thaliana.
