We report here the identification of a pollen-specific gene from Zea mays that contains multiple Ser-(Pro)n repeats, the motif found in the cell wall-associated extensins. Sequence analysis reveals that the encoded protein has a putative globular domain at the N terminus and an extensin-like domain at the C terminus. The Pex1 (pollen extensin-like) gene is expressed exclusively in pollen, not in vegetative or female tissues, and is not induced in leaves upon wounding. We propose that the encoded ...[more]
