AbstractThe presence of the protein Ole e 1 (the olive pollen major allergen) and its transcripts during in-vitro pollen germination have been analyzed. The results obtained showed that: a) a large amount of the protein (with three variants) was found in both the mature and the germinating pollen grain, b) the protein was also secreted to the aqueous germination medium, c) Ole e 1 gene was highly expressed in both the mature and the germinating pollen grain, and d) the allergen was immunolocalized in association with dilated rough endoplasmic reticulum cisternae. These findings clearly support the idea of Ole e 1 playing a role of paramount importance in pollen germination and pollen tube growth.
