ABSTRACT: Polyacrylamide gel electrophoretic studies of protein patterns and esterase zymograms of one isolate of the known, monotypic species of the genus Synecphalastrum, S. raecmosum Cohn ex Schroeter (S1) and six isolates of the three monosporous varieties belonging to the same new species recently reported in this genus, S. monosporum Zheng et al. var. monosporum (S7, S8, S9), var. cristatum Zheng et al. (S10, S11), and var. pluriproliferum Zheng et al. (S12) have been conducted> Marked differences of the four taxa and similarities of different isolates in the same taxon were shown in both protein patterns and esterase zymograms. Similarity percentages calculated also revealed the the threee new varieties were closely related to each other and all of them were, though in less degree, closely related to S. racemosumtoo. These results are thought to be helpful in confirming the establishment of the three new varieties as well as their inclusing in the same species and also in the same genus with S. racemosum based on morphological studies. Polyacrylamide gel edectrophoresis is thought to be a useful supplementary tool for classifying Synecphalastrum.
