摘要：

Pythium sp., the causative organism of red rot disease, isolated from Porphyra yezoensis from Wando in Korea was compared with those from Miyagi, Aichi, and Fukuoka Prefectures by means of electrophoretic patterns of soluble proteins and isozymes. Native and sodium dodecylsulfate-polyacrylamide gel electrophoretic patterns of soluble proteins revealed small but significant differences among the four isolates. Among the 14 detected enzymes, catalase (CAT), carboxylesterase (CE), glucose-6-phosphate dehydrogenase (G6PD), glucosephosphate isomerase (GPI), isocitrate dehydrogenase (IDH), malate dehydrogenase (MDH), superoxide dismutase (SOD), and xanthine dehydrogenase (XDH) possessed isozymes. The dissimilarity value of isozyme banding patterns for four isolates by unweighted pair-group method using arithmetic averages (UPGMA) cluster analysis was highest (0.51) between the isolate from Fukuoka and those from Miyagi and Aichi, and lowest (0.19) between the isolate from Miyagi and that from Aichi. Cluster analysis of data from isozyme banding patterns grouped the isolates from Miyagi and Aichi. These results indicate that the isolates from Miyagi and Aichi are similar, but each isolate from Wando and Fukuoka differed slightly from those of Miyagi and Aichi.
