WebJun 19, 2009 · Accumulation of the tasiRNA sensor in root meristems. (a) The tasiRNA sensor is detected throughout the root meristem, most strongly in the outer cell layers, in … WebSep 16, 2024 · The biogenesis of phasiRNA is highly similar to that of trans-acting siRNA (tasiRNA) (Deng et al. 2024), which was initially discovered in A. thaliana (Vazquez et al. 2004). TasiRNA genes (TAS) usually encode non-coding transcripts while phasiRNA genes are mainly protein-coding genes. In fact, growing evidence reveals that the distinguish ...

WebThe requirement of RDR6 for tasiRNA biogenesis integrates RDR6 into the miR156-miR390-tasiRNA network; however, to the best of our current knowledge, miR534a and DCL3 both act independently of the miR156-miR390-tasiRNA pathway to regulate bud and leafy gametophore production. Trans-acting siRNA (abbreviated "ta-siRNA" or "tasiRNA") are a class of small interfering RNA (siRNA) that repress gene expression through post-transcriptional gene silencing in land plants. Precursor transcripts from TAS loci are polyadenylated and converted to double-stranded RNA, and … See more ta-siRNA were originally detected in 2004 in the flowering plant Arabidopsis thaliana. Initial descriptions found involvement of the plant protein suppressor of gene silencing 3 (SGS3), and the enzyme RNA-dependant RNA … See more Ta-siRNAs are generated from non-coding transcripts through Argonaute-mediated miRNA-guided cleavage followed by conversion to double stranded RNA by RDR6. The resulting dsRNA is further processed by dicer-like enzyme 4 (DCL4) to produce a … See more Endogenous ta-siRNAs act via hetero-silencing, which means that the genes they target for cleavage and repression do not have much resemblance to the genes from which the … See more In addition to being present in A. thaliana, evidence of ta-siRNAs has also been found in the moss Physcomitrella patens, maize, Oryza sativa (rice), and other plants. TAS3 trans-acting short-interfering RNA targeting auxin response factors ("tasiR-ARF") is an … See more http://p-sams.carringtonlab.org/faq ravenworks controller
