Identification of trans‐acting siRNAs in moss and an RNA‐dependent RNA polymerase required for their biogenesis [PDF]

open access: bronzeThe Plant Journal, 2006
Summary 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 from non‐coding transcripts (TAS) that are converted into dsRNA by a RNA‐dependent RNA polymerase (RDR6), following their initial miRNA‐guided cleavage.

Bioinformatic prediction and experimental validation of a microRNA-directed tandem trans-acting siRNA cascade in Arabidopsis [PDF]

open access: greenProceedings of the National Academy of Sciences, 2007
Small RNAs play pivotal roles in regulating gene expression in higher eukaryotes. Among them, trans-acting siRNAs (ta-siRNAs) are a class of small RNAs that regulate plant development. The biogenesis of ta-siRNA depends on microRNA-targeted cleavage followed by the DCL4-mediated production of small RNAs phased in 21-nt increments relative ...

DICER-LIKE1 processedtrans-actingsiRNAs mediate DNA methylation [PDF]

open access: bronzePlant Signaling & Behavior, 2013
Small non-coding RNAs (sRNAs) emerge as exquisite molecules that are guided for transcriptional and posttranscriptional gene regulation in eukaryotes. As one class of most important sRNAs in plants, trans-acting small interfering RNAs (ta-siRNAs) initiate from microRNA (miRNA) - mediated cleavage of TAS gene transcripts and subsequently are stabilized ...

Biogenesis of <i>trans</i>-acting siRNAs, endogenous secondary siRNAs in plants

open access: goldGenes & Genetic Systems, 2013
Trans-acting small interfering RNAs (tasiRNAs) are plant-specific endogenous siRNAs that control non-identical mRNAs via cleavage. The production of tasiRNAs is triggered by cleavage of capped and polyadenylated primary TAS transcripts (pri-TASs) by specific miRNAs.

SGS3 and SGS2/SDE1/RDR6 are required for juvenile development and the production of trans-acting siRNAs in Arabidopsis [PDF]

open access: goldGenes & Development, 2004
Higher plants undergo a transition from a juvenile to an adult phase of vegetative development prior to flowering. Screens for mutants that undergo this transition precociously produced alleles of two genes required for posttranscriptional gene silencing (PTGS)—SUPPRESSOR OF GENE SILENCING3 (SGS3) and SUPPRESSOR OF GENE SILENCING2(SGS2)/SILENCING ...

Effects of type I Diacylglycerol O-acyltransferase (DGAT1) genes on soybean (Glycine max L.) seed composition

open access: yesScientific Reports, 2021
Type I Diacylglycerol acyltransferase (DGAT1) catalyzes the final step of the biosynthesis process of triacylglycerol (TAG), the major storage lipids in plant seeds, through the esterification of diacylglycerol (DAG).

The N-terminal extension of Arabidopsis ARGONAUTE 1 is essential for microRNA activities.

open access: yesPLoS 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 ...

Misregulation of AUXIN RESPONSE FACTOR 8 underlies the developmental abnormalities caused by three distinct viral silencing suppressors in Arabidopsis. [PDF]

open access: yesPLoS 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 ...

Regulation of small RNA accumulation in the maize shoot apex. [PDF]

open access: yesPLoS 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 ...
