Abstract

|
To investigate taxonomical relationships of Fusurium species, esterase-α, -β, acid phosphatase, malate dehydrogenase, peroxidase and polygalacturanase were extracted and the isozyme patterns were compared by using polyacrylamide gel electrophoretic analysis. Only polygalacturonase was monozyme and the other enzymes showed little differences in banding patterns. Genetic simiiarities based on the isozyme banding patterns were as follows: the interspecific similarity between F. subglatinans and F. moniliforme in Liseola showed the closest relationship of 74.3% of all species studies. And the similarity between section Elegans and section Liseola was 45.4%. F. napiforme and F. nygamai showed the similartty of 64.7%, similar to the correlation between species in the same section. The similarity of these two species to Liseola and Elegans showed 55.2% and 45.4%, being revealed that they would be closer to Liseola than Elegans. However, these results were similar to those of any other sections. Therefore it suggested that these 2 spades should be in a different section from any other sections. And F. graminearum showed the similarity of 28.2% to the other 6 species.
