Expanding roles for mirnas and sirnas in cell regulation Kenji Nakahara and Richard W Carthew 1
... Conclusions It is most likely that gene silencing based on siRNAs arose early in eukaryote evolution. This then provided the means for metazoans to evolve another mechanism based on endogenous genes encoding ...

Control of translation and mrna degradation by mirnas and sirnas
... A key issue in miRNA/siRNA function is the speci- ficity of their interactions with their target mRNAs and how each interaction leads to discrete downstream con- sequences. From a number of experiments, some key ...

Biogenesis of phased siRNAs on membrane-bound polysomes in Arabidopsis.
... However, we do not believe that MBPs offer an optimal environment for phasiRNA production. We found that many MIR genes produce 22-nt isoforms due to imprecision in DCL1 processing, yet most 22-nt miRNA isoforms do not ...
