Biosynthesis and Regulation of Phenylpropanoids in Plants (2017, background): “…are recognized by 22nt miR173, which triggers the production of phased ta-siRNA downstream from the miR173-guided cleavage site (Allen et al., 2005; Montgomery et al., 2008a). ta-siRNAs derived from AtTAS1 and AtTAS2 target several pentatricopeptide repeat-containing gene (AtPPR) transcripts and…”
Origin, biogenesis, and activity of plant microRNAs. (2009, neutral): “Studies from several laboratories concurred in the finding that the 50 last nucleotide of small RNA guide strands determines (albeit not always) the identities of at least some of the recruited AGO proteins (Mi et al., 2008; Montgomery et al., 2008a; Takeda et al., 2008).”
Auxin control of root development. (2010, background): “The microRNA390 participates the generation of mature TAS3 tasiRNAs, which target ARF3 and ARF4 transcripts (Montgomery et al. 2008).”
Evolution and Functional Diversification of MIRNA Genes (2011, background): “The mechanisms underlying this distinction are not yet known, although it was postulated that miRNA size affects an AGO1 functional state that mediates the recruitment, either directly or indirectly, of RDR6 (Chen et al., 2010; Cuperus et al., 2010a). miRNA-Directed DNAMethylation A subset of miRNA ”
Small RNAs and Their Roles in Plant Development (2009, methodology): “AGO7 is unique in that it preferentially associates with a single miRNA, miR390, to trigger the production of ta-siRNAs (Montgomery et al. 2008a).”
Small silencing RNAs: an expanding universe (2009, neutral): “Only one of these sites is efficiently cleaved by miR-390, but binding of the miRNA to both sites seems to be required to initiate conversion of the TAS3 transcript to dsRNA by RDR6 (Ref”
MicroRNAs as master regulators of the plant NB-LRR defense gene family via the production of phased, trans-acting siRNAs. (2011, background): “Montgomery et al. (2008a) demonstrated that miR390 is selectively bound by AGO7, and this AGO7– miR390 complex is required at the noncleaving TAS3 target site for tasiRNA biogenesis; they inferred that AGO7 binding may be a requirement for the two-hit tasiRNA pathway.”
Roles of plant small RNAs in biotic stress responses. (2009, background): “Assuming the 5′ nt bias for sRNA sorting into specific AGOs applies to vsRNAs (44, 48, 68), viral production of large amounts of vsRNA with 5′-terminal U could possibly saturate AGO1 to impair its action in antiviral defense and possibly in innate immunity mediated by endogenous sRNAs.”
Plant microRNAs: new players in functional genomics (2013, neutral): “Several developmental programs were detected that involved miRNAs, such as root initiation and development (Montgomery et al. 2008; Marin et al. 2010), vascular development (Yu et al.”
DNA methylation mediated by a microRNA pathway. (2010, background): “, 2007), whereas in plants, the prevailing 50-terminal U of miRNAs contributes to their specific loading into AGO1, which has the strongest binding affinity to sRNAs that initiate with U (Mi et al., 2008; Montgomery et al., 2008; Takeda et al., 2008).”
Endogenous siRNA and miRNA targets identified by sequencing of the Arabidopsis degradome. (2008, background): “One recent model for secondary siRNA biogenesis from the TAS3a locus invokes specific stabilization of the 50 cleavage product, which serves as a template for siRNA production [29].”
A three-dimensional view of the molecular machinery of RNA interference (2009, background): “In the plant Arabidopsis thaliana , distinct types of small non-coding RNA associate with different Argonaute proteins on the basis of the identity of the 5′ nucleotid”
