Plant genomes are the source of large numbers of small RNAs, generated via a variety of
genetically separable pathways. Several of these pathways converge in the production of …

Several varieties of small RNAs including microRNAs (miRNAs) and small interfering RNAs
(siRNAs) are generated in plants to regulate development, genome stability and response to …

Trans-acting small interfering RNAs (tasiRNAs) are a major class of small RNAs performing
essential biological functions in plants. The first reported tasiRNA pathway, that of miR173 …

It has been almost 30 years since RNA interference (RNAi) was shown to silence genes via
double-stranded RNAs (dsRNAs) in Caenorhabditis elegans (Fire et al. 1998). 20–30 …

Phased secondary small interfering RNAs (phasiRNAs) constitute a major category of small
RNAs in plants, but most of their functions are still poorly defined. Some phasiRNAs, known …

Trans‐acting small interfering RNAs (tasiRNAs) are a class of higher‐plant endogenous
siRNAs that, like miRNAs, direct the cleavage of non‐identical transcripts. tasiRNAs derive …

Here we describe a set of endogenous short interfering RNAs (siRNAs) in Arabidopsis,
some of which direct the cleavage of endogenous mRNAs. These siRNAs correspond to …

MicroRNAs (miRNAs) and short interfering RNAs (siRNAs), 20-to 27-nt in length, are
essential regulatory molecules that act as sequence-specific guides in several processes in …

Plant small RNAs play important roles in transcriptional and posttranscriptional regulation,
with ongoing work demonstrating their functions in diverse pathways. Their roles in defense …

Small RNAs are ubiquitous, versatile repressors and include (1) microRNAs (miRNAs),
processed from mRNA forming stem-loops; and (2) small interfering RNAs (siRNAs), the …
