Plants with altered microRNA metabolism have pleiotropic developmental defects, but direct evidence for microRNAs regulating specific aspects of plant morphogenesis has been lacking. In a genetic screen, we identified the JAW locus, which produces a microRNA that can guide messenger RNA cleavage of several TCP genes controlling leaf development. MicroRNA-guided cleavage of TCP4 mRNA is necessary to prevent aberrant activity of the TCP4 gene expressed from its native promoter. In addition… Expand

TLDR
Studies of individual miRNA/target interactions highlight the involvement of the miRNA-based regulations in a broad range of developmental programs, throughout plant lifecycle. Expand
Role of MicroRNA miR319 in Plant Development
TLDR
Insights into the gene networks that are controlled by the miR319-regulated TCPs demonstrate their participation in multiple biological pathways, from hormone biosynthesis and signaling to cell proliferation and differentiation. Expand
[The role of miR319 in plant development regulation].
TLDR
The miR319 was shown to regulate TCPs transcription factor controlling the fate of plant organ growth such as leaves and flowers and was involved in regulating part of hormone biosynthesis and signal transduction pathways. Expand
Regulation of microRNA on plant development and viral infection
TLDR
The recent studies on miRNA regulatory roles in plant developmental processes, as well as the interference of viral suppressors in miRNA pathway are reviewed to get an insight into the complexity of gene expression regulation in eukaryotic organisms. Expand
MicroRNA Dynamics and Functions During Arabidopsis Embryogenesis
MicroRNAs (miRNAs) are short non-coding RNAs that mediate the repression of target transcripts in plants and animals. Although miRNAs are required throughout plant development, relatively little isExpand
Plant microRNAs and development.
TLDR
The status of research in this dynamic field is reviewed, summarizing recent advances in the understanding of the biogenesis and mechanism of action of plant miRNAs, as well as in the developmental processes they regulate. Expand
Specific Regulation of TCP genes by miR319
TLDR
Genetic evidence indicates that miR159 and miR319 fulfil different roles in vivo, and specific small sequence differences between the miRNAs allow for the specific regulation of TCP transcription factors by miR 319 miRNas. Expand
MicroRNAS and their regulatory roles in plants.
TLDR
The importance of miRNA-directed gene regulation during plant development is now particularly clear and typically at the cores of gene regulatory networks, targeting genes that are themselves regulators, such as those encoding transcription factors and F-box proteins. Expand
Biogenesis, functions and fate of plant microRNAs
TLDR
The identification of a protein that degrade single stranded small RNA has provided some understanding of how miRNA flux is maintained in plants and this review focuses on the genome organization, biogenesis, miRNA activity, and the fate of miRNAs. Expand

MicroRNAs in plants.
TLDR
Mutation of an Arabidopsis Dicer homolog, CARPEL FACTORY, prevents the accumulation of miRNAs, showing that similar mechanisms direct miRNA processing in plants and animals. Expand
Cleavage of Scarecrow-like mRNA Targets Directed by a Class of Arabidopsis miRNA
TLDR
This work shows that Arabidopsis thaliana miRNA 39 (also known as miR171), a 21-ribonucleotide species that accumulates predominantly in inflorescence tissues, is produced from an intergenic region in chromosome III and functionally interacts with mRNA targets encoding several members of the Scarecrow-like (SCL) family of putative transcription factors.

  • 2004
TLDR
MiRNA172 likely acts in cell-fate specification as a translational repressor of APETALA2 in Arabidopsis flower development and results in floral organ identity defects similar to those in loss-of-function apetala2 mutants. Expand
Negative Feedback Regulation of Dicer-Like1 in Arabidopsis by microRNA-Guided mRNA Degradation
TLDR
It is shown that DCL1 mRNA occurs in multiple forms, including truncated molecules that result from aberrant pre-mRNA processing, and is subject to negative feedback regulation through the activity of a miRNA. Expand
CARPEL FACTORY, a Dicer Homolog, and HEN1, a Novel Protein, Act in microRNA Metabolism in Arabidopsis thaliana
TLDR
HEN1 is a new player in miRNAs accumulation in Arabidopsis, and HEN1 homologs in metazoans may have a similar function of the two genes, possibly in miRNA metabolism. Expand

TLDR
This work predicts regulatory targets for 14 Arabidopsis microRNAs (miRNAs) by identifying mRNAs with near complementarity and identifies members of transcription factor gene families involved in developmental patterning or cell differentiation. Expand
Hes1 is a target of microRNA-23 during retinoic-acid-induced neuronal differentiation of NT2 cells
TLDR
Results indicate that miR-23 regulates the expression of Hes1 at the post-transcriptional level, and participates in retinoic-acid-induced neuronal differentiation of NT2 cells. Expand
P1/HC-Pro, a viral suppressor of RNA silencing, interferes with Arabidopsis development and miRNA unction.
TLDR
The basis for TuMV- and other virus-induced disease in plants may be explained, at least partly, by interference with miRNA-controlled developmental pathways that share components with the antiviral RNA-silencing pathway. Expand
A biochemical framework for RNA silencing in plants.
TLDR
This finding supports the view that plant miRNAs direct RNAi and that miRNA-specified mRNA destruction is important for proper plant development and endonuclease complexes guided by small RNAs are a common feature of RNA silencing in both animals and plants. Expand
A species of small antisense RNA in posttranscriptional gene silencing in plants.
TLDR
The 25-nucleotide antisense RNA detected in transgene-induced PTGS is likely synthesized from an RNA template and may represent the specificity determinant of PTGS. Expand
