Isolation and expression of an allergen-like mRNA from ethylene-treated Sambucus nigra leaflet abscission zones

A novel mRNA (Sn20) was isolated from Sambucus nigra (elder) leaflet abscission zone cells. The transcript specifically accumulates in abscission zone tissue after exposure to ethylene (10 µl l−1) for 18 h. The putative peptide encoded by Sn20 shows close homology with the Olee1 pollen allergens. A...

Zusammenfassung:	A novel mRNA (Sn20) was isolated from Sambucus nigra (elder) leaflet abscission zone cells. The transcript specifically accumulates in abscission zone tissue after exposure to ethylene (10 µl l−1) for 18 h. The putative peptide encoded by Sn20 shows close homology with the Olee1 pollen allergens. A possible role for this protein in cell wall loosening is discussed.
