Relationship between accumulation of cell wall extensin and resistance in soyabean to Cercospora


, : Relationship between accumulation of cell wall extensin and resistance in soyabean to Cercospora. Acta Phytopathologica Sinica 21(3): 217-222

The types and synthesis of extensin were studied, using an antibody against extensin from carrot callus, in hypocotyls of soyabean cultivars Hefeng 29, Fengshou 10 and Suinong 4 which are highly resistant, moderately resistant and susceptible to Cercospora sojina, respectively. Western blotting and dot-ELISA analysis showed that the extensin extracted from cell walls of soyabean hypocotyls by CaCl2 was electrophoretically and immunologically similar to the extensin in carrot callus.
