Abstract
TheNTP303 gene of tobacco is expressed only in bicellular pollen. The minimal pollen-specific promoter of the gene is located between −103 and −51 upstream of the transcriptional start site. Using gel mobility shift assays, we demonstrated that this minimal functional promoter interacts with a leaf nuclear GT-1 binding activity. This finding suggests that ubiquitous transcription factors are involved in the pollen-specific expression of the gene in vivo.
