  • Title: cis-Acting sequences required for light-responsive expression of the psbDII gene in Synechococcus sp. strain PCC 7942.
    Author: Anandan S, Golden SS.
    Journal: J Bacteriol; 1997 Nov; 179(21):6865-70. PubMed ID: 9352943.
    Abstract:
    We analyzed the sequences required for promoter activity and high-light responsiveness of the psbDII gene in the cyanobacterium Synechococcus sp. strain PCC 7942 by using transcriptional fusions to a lacZ reporter gene. The basal promoter drives high constitutive expression, although no canonical -35 element is evident. The smallest fragment that showed clear light-responsive expression extends from -38 to +160, which includes 52 bp of the psbDII open reading frame. Sequences downstream from the promoter, within the untranslated leader region from +11 to +24, were required for high-light induction.
