对中国柑桔上分离到的25个柑桔炭疽病菌分离系,进行酯酶同工酯及可溶性蛋白质的凝胶电泳。结果表明:病菌分离系的酯酶同工酶谱存在着差异,并且依据此差异划分出三个生理分化的类型;病菌分离系的可溶性蛋白质凝胶电泳的图谱,在其种内基本上保持一致,不能用可溶性蛋白质的凝胶电泳进行柑桔炭疽病菌生理分化的研究。 Isolation of 25 citrus citrus isolates from Chinese citrus fruits was carried out by gel electrophoresis of esterase isoforms and soluble proteins. The results showed that there were differences in the esterase isoenzyme patterns of the isolates of bacteria, and the three types of physiological differentiation were divided according to the differences. The map of soluble protein gel electrophoresis of the isolates of bacteria was basically consistent within their species , Can not use soluble protein gel electrophoresis citrus anthracnose physiological differentiation.
