Abstract The NTP303 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.
