TABLE 3 .
Periodic transcriptional dynamics during a consistent diel light:dark cycle and extended darkness
| Organism (growth condition) | No. of transcripts (%) with 24-h periodicitya under: |
|
|---|---|---|
| 13:11 light:dark cycle | Extended darkness | |
| Prochlorococcus (grown alone) | 1,515 (69) | 127 (6) |
| Prochlorococcus (grown with Alteromonas) | 1,877 (85) | 555 (25) |
| Alteromonas (grown with Prochlorococcus) | 530 (13) | 2 (0.05) |
a
Values are the number of ORFs whose relative transcript abundance oscillated with significant 24-h periodicity across the first 48 h of the experiment and their percentage of the 2,198 total annotated Prochlorococcus genes or 4,213 total annotated Alteromonas genes.
