title: Style antigens of Prunus avium L.
abstract: Antiserum to a protein fraction of an extract of mature styles of P. avium cv. Lambert (S 3 S 4) was raised in rabbits. Two major antigenic components of the style extracts were detected by immunoelectrophoresis and immunodiffusion. The presence of one antigen (S-antigen) correlated with a particular S-genotype (S 3 S 4). This antigen is restricted to mature styles of P. avium. The second antigen (P-antigen) was detected in styles of all Prunus species examined, but not in styles of other species of the Rosaceae. The S-antigen is positively charged and the P-antigen negatively charged at pH 8.8.
