| One of these oxygen sensing regulatory systems is the fumarate and nitrate reduction transcriptional regulator. |
| The missing ORFs are the ones encoding BVMO4 and a TetR transcriptional regulator gene. |
| The latter participate in numerous morphogenetic and physiological events, including hematopoiesis, through synergistic interactions with other transcriptional activators. |
| To double check, the team examined their creation's transcriptional profile. |
| Passage through mitosis is driven by precisely-timed changes in transcriptional regulation and protein degradation. |
| Although control of gene expression at the transcriptional level is a key regulatory mechanism controlling carotenogenesis in chromoplasts, it is not the only one. |
