Abstract
A DNA segment from the upstream untranscribed region of a maize ubiquitin gene is disclosed. This ubiquitin promoter region, which comprises heat shock consensus elements, initiates and regulates the transcription of genes placed under its control. Recombinant DNA molecules are also described in which a ubiquitin promoter is combined with a plant expressible structural gene for regulated expression of the structural gene and for regulated control of expression when stressed with elevated temperatures. Such recombinant DNA molecules are introduced into plant tissue so that the promoter/structural gene combination is expressed.
