用蛋白质等电聚焦电泳方法对马铃薯软腐抗病品种丰收白和高感品种费乌瑞它在发病过程中的蛋白质变化进行了研究.参照Ahl等(1982)的方法抽提两个品种薯块中的水溶性蛋白质。在健组织中,丰收白的总可溶性蛋白含量(0.67mg/g鲜重)比费乌瑞它(0.45)高50%。用薯片接种软腐欧氏杆菌株StEcc—12(Erwinia carotovora subsp.carotovora)后,抗病品种薯片病健交界处的蛋白含量提高,接种24小时后的蛋白质含量分别比对照组织和腐烂组织高15%和45%,而接
Protein isoelectric focusing electrophoresis method of soft-rot resistant varieties of potato harvest and high susceptibility Feirui its protein changes in the course of the disease were studied.According to Ahl et al (1982) extraction of two varieties of potato In the water-soluble protein. In healthy tissues, harvesting white total soluble protein content (0.67 mg / g fresh weight) was 50% higher than feretiain (0.45). After inoculation of Erwinia carotovora subsp. Carotovora with potato chips, the protein content of disease-resistant potato crisps at the juncture of health improvement increased. The content of protein in 24 hours after inoculation was higher than that of control and decayed tissues High 15% and 45%, and then
