An enhancer screen identifies new suppressors of small-RNA-mediated epigenetic gene silencing.
PLoS Genetics, 2021 Small non-protein coding RNAs are involved in pathways that control the genome at the level of chromatin. In Schizosaccharomyces pombe, small interfering RNAs (siRNAs) are required for the faithful propagation of heterochromatin that is found at peri ...

The N-terminal extension of Arabidopsis ARGONAUTE 1 is essential for microRNA activities.
PLoS Genetics, 2023 microRNAs (miRNAs) regulate target gene expression through their ARGONAUTE (AGO) effector protein, mainly AGO1 in Arabidopsis thaliana. In addition to the highly conserved N, PAZ, MID and PIWI domains with known roles in RNA silencing, AGO1 contains a ...

TRANS-ACTING SIRNA3-derived short interfering RNAs confer cleavage of mRNAs in rice
Plant Physiology, 2021 Plant TRANS-ACTING SIRNA3 (TAS3)-derived short interfering RNAs (siRNAs) include tasiR-AUXIN RESPONSE FACTORs (ARFs), which are functionally conserved in targeting ARF genes, and a set of non-tasiR-ARF siRNAs, which have rarely been studied.

Misregulation of AUXIN RESPONSE FACTOR 8 underlies the developmental abnormalities caused by three distinct viral silencing suppressors in Arabidopsis. [PDF]
PLoS Pathogens, 2011 In Arabidopsis, micro (mi)RNAs and trans-acting (ta-si)RNAs synthesized directly or indirectly through the DICER-LIKE-1 (DCL1) ribonuclease have roles in patterning and hormonal responses, while DCL2,3,4-dependent small-interfering (si)RNAs are mainly ...

PLoS ONE, 2008 Myelin-associated glycoprotein (MAG) has been detected in Schwann cells prior to the onset of myelination, suggesting its functions in the initiation of myelination. However, transcriptional regulatory mechanisms of MAG remain to be elucidated.

Regulation of small RNA accumulation in the maize shoot apex. [PDF]
PLoS Genetics, 2009 MicroRNAs (miRNAs) and trans-acting siRNAs (ta-siRNAs) are essential to the establishment of adaxial-abaxial (dorsoventral) leaf polarity. Tas3-derived ta-siRNAs define the adaxial side of the leaf by restricting the expression domain of miRNA miR166 ...

Role of RNA Interference (RNAi) in the Moss Physcomitrella patens [PDF]
, 2013 RNA interference (RNAi) is a mechanism that regulates genes by either transcriptional (TGS) or posttranscriptional gene silencing (PTGS), required for genome maintenance and proper development of an organism.

Characterization of unique small RNA populations from rice grain.
PLoS ONE, 2008 Small RNAs (approximately 20 to 24 nucleotides) function as naturally occurring molecules critical in developmental pathways in plants and animals. Here we analyze small RNA populations from mature rice grain and seedlings by pyrosequencing.
