Characterization of a stigmatic component from Papaver rhoeas L. which exhibits the specific activity of a self-incompatibility (S-) gene product

Extracts prepared from stigmatic tissue of Papaver rhoeas L. have been fractionated and monitored for S-gene product activity. A basic glycoprotein, with an apparent MW of 22 kDa, which exhibits the specific activity expected of a protein encoded by the self-incompatibility (S-) gene has been identi...

Zusammenfassung:	Extracts prepared from stigmatic tissue of Papaver rhoeas L. have been fractionated and monitored for S-gene product activity. A basic glycoprotein, with an apparent MW of 22 kDa, which exhibits the specific activity expected of a protein encoded by the self-incompatibility (S-) gene has been identified. Similar preparations using extracts from other tissues have revealed that this protein is unique to mature stigma tissue.
