Photosynthesis nuclear genes generally lack TATA-boxes: a tobacco photosystem I gene responds to light through an initiator.

The Plant journal : for cell and molecular biology - 1 Jan 2002

Nakamura Masayuki, Tsunoda Tatsuhiko, Obokata Junichi

Abstract excerpt

The promoter architecture of the nuclear-encoded photosystem I genes was studied using a tobacco gene, psaDb, as a model case. Linker scanning mutations revealed that the psaDb promoter does not have a TATA box. Instead, pyrimidine-rich Initiator (Inr) elements that overlap the transcription start sites are essential for light-responsive transcription of this gene. When the psaDb promoter was mutated to have a...
