Interaction between a coating-borne peptide of the Brassica pollen grain and stigmatic S (self-incompatibility)-locus-specific glycoproteins.

Abstract:

Methods are described for the removal of the sporophytic pollen grain coating of Brassica oleracea and for the isolation of coat polypeptides. The coat contains a small number of proteins ranging from 6 to 45 kDa. Many of the larger proteins are glycosylated, while all carry high positive charges resulting in pI values from 8.5 to 11. Polypeptides with pI values of 9.5, 9.0, and 8.5 possess strong esterase activity. No major differences could be detected in either pI values or molecular masse...
