DICER-LIKE1: blind men and elephants in Arabidopsis development

Genetic studies of embryo, ovule and flower development in Arabidopsis thaliana have led to the independent isolation of different mutant alleles of a single gene ( SIN1/ SUS1/ CAF, now renamed DCL1) that encodes a complex RNA-processing enzyme. DCL1 shows similarity to the Dicer group of genes, whi...

Description
Summary:Genetic studies of embryo, ovule and flower development in Arabidopsis thaliana have led to the independent isolation of different mutant alleles of a single gene ( SIN1/ SUS1/ CAF, now renamed DCL1) that encodes a complex RNA-processing enzyme. DCL1 shows similarity to the Dicer group of genes, which are required for RNA silencing in Drosophila and Caenorhabditis. These recent findings identify a novel but conserved mechanism of post-transcriptional gene regulation that is important for development in eukaryotes. DICER-LIKE1 illuminates a central regulatory pathway for Arabidopsis development-recent studies reveal a novel mechanism of post-transcriptional gene regulation mediated by RNA silencing.
