Abstract:
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.
