Abstract excerpt
We had earlier reported that mutations to G and C at the seventh and eighth positions in the prototype TATA-box TCACTATATATAG inhibited light-dependent activation of transcription from the promoter. In this study, we characterized mutations at the ninth position of the prototype TATA-box. Substitution of T at the ninth position with G or C enhanced transcription from the promoter in transgenic tobacco (Nicotiana...
