e0“The in vitro protein synthetic activity of 80S ribosomes from leaves of dark-grown corn seedlings was enhanced (at low Mg(2+) levels) by a 5-minute red light treatment applied 2 hours prior to tissue harvest”

Other claims from this paper (6)
- Intervention effect Immediate far red treatment reversed the red light effect.
- Observation Ribosome activity first increased within 30 minutes and then rapidly over the next 1.5 hours.
- Observation Ribosome activity did not increase further after 2 to 3 hours.
- Mechanism The change in activity was linked partly to increased peptidyl-tRNA associated with ribosomes.
- Intervention effect Removing peptidyl-tRNA reversed the red light effect.
- Observation Reversal of continuous white light activation required both salt washing and removal of peptidyl-tRNA.
