The present invention relates to transcription regulating sequences from Solanaceae triose-phosphate translocator (TPT) genes and their use in plant expression cassettes. Preferably, the transcription regulating sequence is from the Solanum tuberosum triose-phosphate translocator gene. The transcription regulating sequences preferably exhibit strong expression activity in all tissues beside the reproductive organs (e.g., flowers, seed) and are especially useful for expression in potato tubers.
