AGO1-miR173 complex initiates phased siRNA formation in plants

WebMar 1, 2009 · Trans‐acting small interfering RNAs (tasiRNAs) comprise a class of endogenous small RNAs that are generated from TAS gene‐derived transcripts after these are cleaved at a microRNA (miRNA) target site. Arabidopsis thaliana has four families of TAS genes: miR173 triggers tasiRNA production from TAS1 and TAS2, miR390 from … WebAnalysis of ta-siRNA synthesis mutants and mutated ARF3-overexpressing plants that escape the tasiRNA-ARF target indicated that self-pollination was hampered by short stamens in plants under drought and high-salinity stress. Microarray analysis of flower buds of rdr6 and wild-type plants under drought stress and nonstressed conditions revealed ... dried fruit and nuts gift

Role of phasiRNAs from two distinct phasing frames of

Web小干扰RNA（siRNA），有时称为短干扰RNA或沉默RNA，是一类双链RNA分子，长度为20-25个碱基对，类似于miRNA，并且在 RNA干扰 （RNAi）途径内操作。 它干扰了表达与 … WebSep 6, 2005 · A series of recent reports described tasiRNAs, a class of small RNAs that requires components of both the miRNA and siRNA pathways for their biogenesis, establishing a link between the miRNA and siRNA pathways ( 13 – 15) ( Fig. 1 ). Web4 C. Concomitant with the reduction of TAS1 tasiRNA-mediated cleavage, expression of At1g51670, a target of TAS1 tasiRNA, was upregulated at 4 C in the wild type but not in a dicer-like enzyme (DCL) 4 mutant (dcl4-2), which is impaired in tasiRNA biogenesis.
