Ancient trans-Acting siRNAs Confer Robustness and Sensitivity onto the Auxin Response [PDF]
ABSTRACTNovel developmental programs often evolve via cooption of existing genetic networks. To understand this process, we explored cooption of theTAS3tasiRNA pathway in the mossPhyscomitrella patens. We find an ancestral function for this repeatedly redeployed pathway in the spatial regulation of a conserved set of Auxin Response Factors.

MicroRNAs as master regulators of the plant NB-LRR defense gene family via the production of phased, trans-acting siRNAs [PDF]
Legumes and many nonleguminous plants enter symbiotic interactions with microbes, and it is poorly understood how host plants respond to promote beneficial, symbiotic microbial interactions while suppressing those that are deleterious or pathogenic. Trans-acting siRNAs (tasiRNAs) negatively regulate target transcripts and are characterized by siRNAs ...

SUMMARYTargeted gene silencing using small regulatory RNAs is a widely used technique for genetic studies in plants. Artificial microRNAs are one common approach, as they have the advantage of producing just a single functional small RNA, which can be designed for high target specificity and low off‐target effects.

Assorted Processing of Synthetic Trans-Acting siRNAs and Its Activity in Antiviral Resistance
The use of syn-tasiRNAs has been proposed as an RNA interference technique alternative to those previously described: hairpin based, virus induced gene silencing or artificial miRNAs. In this study we engineered the TAS1c locus to impair Plum pox virus (PPV) infection by replacing the five native siRNAs with two 210-bp fragments from the CP and the 3 ...

Identification of novel drought-responsive microRNAs and trans-acting siRNAs from Sorghum bicolor (L.) Moench by high-throughput sequencing analysis [PDF]
Small non-coding RNAs (sRNAs) namely microRNAs (miRNAs) and trans-acting small interfering RNAs (tasi-RNAs) play a crucial role in post-transcriptional regulation of gene expression and thus the control plant development and stress responses. In order to identify drought-responsive miRNAs and tasi-RNAs in sorghum, we constructed small RNA libraries ...

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

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

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