MicroRNAs (miRNAs) are a class of small, endogenous RNAs of 21–25 nucleotides (nts) in
length. They play an important regulatory role in animals and plants by targeting specific …

Abstract 'RNA silencing'refers to related processes of post-trancriptional control of gene
expression found in plants, animals and fungi. A unifying feature of RNA silencing is that it …

The 21-nucleotide small temporal RNA (stRNA) let-7 regulates developmental timing in
Caenorhabditis elegans and probably in other bilateral animals. We present in vivo and in …

MicroRNAs (miRNAs) are an extensive class of∼ 22-nucleotide noncoding RNAs thought to
regulate gene expression in metazoans. We find that miRNAs are also present in plants …

We predict regulatory targets for 14 Arabidopsis microRNAs (miRNAs) by identifying mRNAs
with near complementarity. Complementary sites within predicted targets are conserved in …

SPL3, SPL4 and SPL5 (SPL3/4/5) are closely related members of the SQUAMOSA
PROMOTER BINDING PROTEIN-LIKE family of transcription factors in Arabidopsis, and …

Duplexes of 21–23 nucleotide (nt) RNAs are the sequence‐specific mediators of RNA
interference (RNAi) and post‐transcriptional gene silencing (PTGS). Synthetic, short …

Background: In metazoans, microRNAs, or miRNAs, constitute a growing family of small
regulatory RNAs that are usually 19–25 nucleotides in length. They are processed from …

The molecular basis for virus-induced disease in plants has been a long-standing mystery.
Infection of Arabidopsis by Turnip mosaic virus (TuMV) induces a number of developmental …

Double-stranded RNA has been shown to induce gene silencing in diverse eukaryotes and
by a variety of pathways. We have examined the taxonomic distribution and the phylogenetic …
