Other claims from this paper (7)
- Intervention effect The Fed-1 internal light response element rapidly reduced translational efficiency after darkness.
- Intervention effect iLRE-containing mRNAs dissociated from polyribosomes within 20 minutes of dark transfer.
- Observation The translation and polyribosome changes preceded decline in mRNA abundance.
- Intervention effect Reillumination rapidly reversed mRNA polyribosome association.
- Mechanism In darkness, much Fed-1 mRNA dissociates from polyribosomes and is subsequently degraded in the authors model.
- Intervention effect A significant portion of total tobacco leaf mRNA shifted away from polyribosomes after 20 minutes in darkness.
- Observation Some cytoplasmic mRNAs encoding photosynthesis proteins belonged to the rapidly down-regulated translation class, but others did not.
