Increase in rate of synthesis of most enzymes studied in light compared to dark

Range 50 to 100 %
Organism Thale cress Arabidopsis thaliana
Reference Piques et al., Ribosome and transcript copy numbers, polysome occupancy and enzyme dynamics in Arabidopsis. Mol Syst Biol. 2009 5: 314 p.5 right column 4th paragraphPubMed ID19888209
Method The rate of synthesis of the proteins encoded by these 98 transcripts was estimated from the transcript abundance in the SPS (small polysomal fraction) and LPS (large polysomal fraction) fractions, multiplied by the ribosome density per translating transcript
Comments Most enzymes showed an estimated 50 to 100% increase in the rate of synthesis in the light period compared to the dark period.
