- Title
The copper microRNAs.
- Authors
Pilon, Marinus
- Abstract
Copper (Cu) microRNAs are upregulated by Cu deficiency and mediate the post-transcriptional downregulation of transcripts that encode Cu proteins, suggesting a role directly related to Cu. However, expression and phenotypic analyses of coppermicroRNAmutants and over-expressors have suggested roles mainly in tolerance to abiotic stresses. To reconcile available data, amodel is proposedwhich emphasizes themobile nature of copper microRNAmolecules in the regulation of Cu homeostasis. It is proposed that the Cu-microRNA regulatory circuits are further co-opted by plants to regulate both beneficial and pathogenic interactions with microbes. Further exploration of Cu-microRNA functions that account for the cell-to-cellmobility should give novel insight into plant microbe interactions and the integration of micronutrition and development.
