molecular function |
| GO:0003723 | | RNA binding | | Interacting selectively and non-covalently with an RNA molecule or a portion thereof. |
| GO:0003725 | | double-stranded RNA binding | | Interacting selectively and non-covalently with double-stranded RNA. |
| GO:0035198 | | miRNA binding | | Interacting selectively and non-covalently with a microRNA, a 21-23 nucleotide RNA that is processed from a stem-loop RNA precursor (pre-miRNA) that is encoded within plant and animal genomes. |
| GO:0005515 | | protein binding | | Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules). |
| GO:0004525 | | ribonuclease III activity | | Catalysis of the endonucleolytic cleavage of RNA with 5'-phosphomonoesters and 3'-OH termini; makes two staggered cuts in both strands of dsRNA, leaving a 3' overhang of 2 nt. |
biological process |
| GO:0090502 | | RNA phosphodiester bond hydrolysis, endonucleolytic | | The chemical reactions and pathways involving the hydrolysis of internal 3',5'-phosphodiester bonds in one or two strands of ribonucleotides. |
| GO:0031047 | | gene silencing by RNA | | Any process in which RNA molecules inactivate expression of target genes. |
| GO:0010589 | | leaf proximal/distal pattern formation | | The regionalization process within a leaf by which specific areas of cell differentiation are determined along a proximal/distal axis. |
| GO:0010305 | | leaf vascular tissue pattern formation | | Vascular tissue pattern formation as it occurs in the leaf of vascular plants. |
| GO:0035279 | | mRNA cleavage involved in gene silencing by miRNA | | The process in which microRNAs (miRNAs) direct the cleavage of target mRNAs. Once incorporated into a RNA-induced silencing complex (RISC), a miRNA base pairing with near-perfect complementarity to the target mRNA will typically direct targeted endonucleolytic cleavage of the mRNA. Many plant miRNAs downregulate gene expression through this mechanism. |
| GO:0031054 | | pre-miRNA processing | | Any process involved in the conversion of a pre-microRNA transcript into a mature microRNA molecule. |
| GO:0031053 | | primary miRNA processing | | Any process involved in the conversion of a primary microRNA transcript into a pre-microRNA molecule. |
| GO:0035196 | | production of miRNAs involved in gene silencing by miRNA | | Cleavage of stem-loop RNA precursors into microRNAs (miRNAs), a class of small RNAs that primarily silence genes by blocking the translation of mRNA transcripts into protein. |
| GO:0010267 | | production of ta-siRNAs involved in RNA interference | | Cleavage of double-stranded RNA to form trans-acting small interfering RNA molecules (siRNAs) of 21-23 nucleotides. ta-siRNAs arise from PolII genes and function like miRNAs to guide cleavage of target mRNAs. |
| GO:0009737 | | response to abscisic acid | | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an abscisic acid stimulus. |
| GO:0009733 | | response to auxin | | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an auxin stimulus. |
| GO:0009735 | | response to cytokinin | | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a cytokinin stimulus. |
cellular component |
| GO:0015030 | | Cajal body | | A class of nuclear body, first seen after silver staining by Ramon y Cajal in 1903, enriched in small nuclear ribonucleoproteins, and certain general RNA polymerase II transcription factors; ultrastructurally, they appear as a tangle of coiled, electron-dense threads roughly 0.5 micrometers in diameter; involved in aspects of snRNP biogenesis; the protein coilin serves as a marker for Cajal bodies. Some argue that Cajal bodies are the sites for preassembly of transcriptosomes, unitary particles involved in transcription and processing of RNA. |
| GO:0010445 | | nuclear dicing body | | A small round nuclear body, measuring 0.2-0.8 microns in diameter that is diffusely distributed throughout the nucleoplasm. Several proteins known to be involved in miRNA processing have been localized to these structures. D-bodies are thought to be involved in primary-miRNA processing and/or storage/assembly of miRNA processing complexes. |
| GO:0005634 | | nucleus | | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. |
