Other claims from this paper (8)
- Observation MtMIR166a contains tandem MIR166 copies in one transcriptional unit.
- Mechanism These miRNAs post-transcriptionally regulate class-III HD-ZIP genes associated with nodules.
- Observation HD-ZIP III targets co-expressed spatially with MIR166 in vascular bundles and root and nodule apices.
- Intervention effect MIR166 overexpression reduced symbiotic nodule number.
- Intervention effect MIR166 overexpression reduced lateral root number.
- Intervention effect MIR166 overexpression caused ectopic vascular bundles in roots.
- Mechanism The authors conclude polycistronic plant miRNA precursors can be processed.
- Mechanism MIR166 post-transcriptional regulation is implicated in legume root architecture.
