Other claims from this paper (8)
- Intervention effect Nucleotides in both TATA segments and flanking sequences influenced promoter function in tobacco leaves.
- Intervention effect TATA mutations had variable and sometimes contrasting effects on reporter expression in light versus dark.
- Intervention effect Some TATA mutations inactivated minimal promoter expression in light but not darkness.
- Observation The sequence requirement was less stringent for dark than light expression.
- Intervention effect TATA mutations selectively affected light versus dark expression in chromatin-integrated promoters.
- Intervention effect TATA mutations affected light modulation even with an upstream activator element.
- Association An A at position eight was involved in the promoter red-light response.
- Mechanism TATA-box sequence variation governed formation of alternative transcriptional complexes.
