DH2-dependent trans-acting siRNAs regulate leaf and lemma development in rice
Frontiers in Plant ScienceIn most crops, the development of lateral organs such as leaves and floral organs plays important roles in the architecture of plants and grains and then determines the yield. Establishment of polarity in these lateral organs is one of the most critical events for their morphogenesis.

A pathway for the biogenesis of trans-acting siRNAs in Arabidopsis [PDF]
Genes & Development, 2005 The Arabidopsis genes, TAS2 and TAS1a, produce structurally similar noncoding transcripts that are transformed into short (21-nucleotide [nt]) and long (24-nt) siRNAs by RNA silencing pathways. Some of these short siRNAs direct the cleavage of protein-coding transcripts, and thus function as trans-acting siRNAs (ta-siRNAs).

Partially Redundant Functions of Arabidopsis DICER-like Enzymes and a Role for DCL4 in Producing trans-Acting siRNAs [PDF]
Current Biology, 2005 Arabidopsis encodes four DICER-like (DCL) proteins. DCL1 produces miRNAs, DCL2 produces some virus-derived siRNAs, and DCL3 produces endogenous RDR2-dependent siRNAs, but the role of DCL4 is unknown. We show that DCL4 is the primary processor of endogenous RDR6-dependent trans-acting siRNAs (tasiRNAs).

Identification of novel drought-responsive microRNAs and trans-acting siRNAs from Sorghum bicolor (L.) Moench by high-throughput sequencing analysis [PDF]
Frontiers in Plant Science, 2015 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 ...

MicroRNAs as master regulators of the plant NB-LRR defense gene family via the production of phased, trans-acting siRNAs [PDF]
Genes & Development, 2011 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 ...

Assorted Processing of Synthetic Trans-Acting siRNAs and Its Activity in Antiviral Resistance
PLOS ONE, 2015 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 ...

Frontiers in Plant Science, 2021 Auxin Response Factors (ARFs) constitute a large family of transcription factors that mediate auxin-regulated developmental programs in plants. ARF2, ARF3, and ARF4 are post-transcriptionally regulated by the microRNA390 (miR390)/trans-acting small ...

Gene expression and stress response mediated by the epigenetic regulation of a transposable element small RNA. [PDF]
PLoS Genetics, 2012 The epigenetic activity of transposable elements (TEs) can influence the regulation of genes; though, this regulation is confined to the genes, promoters, and enhancers that neighbor the TE.
