Isoenzymatic analysis of some freshwater Anabaena strains from Southern Italy
Musacchio, A. | Caputo, P. | Bonelli, E.
Seven freshwater Anabaena sp. strains have been examined for esterase, malate dehydrogenase, acid phosphatase and aldolase isozyme patterns. The morphological differences among them did not allow a sure understanding of their relationships, whereas a phylogenetic analysis of the esterase and malate dehydrogenase patterns led to a single fully resolved tree. A phenetic analysis on the same data set resulted in the same pattern of relationships. Successive cultures of the same strains did not show identical band phenotypes, but nevertheless the phenetic and phylogenetic relationships among the various strains did not change.Show more [+] Less [-]
