Four strains of Tuber borchii were grown in liquid medium containing glucose. Evaluation of growth patterns revealed a trend of
exponential growth for only one strain. Subsequently, enzyme levels were assayed and polypeptide and mRNA electrophoretic
profiles were analyzed. Although the four strains were found to have many properties in common such as the growth behaviours for
three strains and the levels of some glycolytic enzymes, the polypeptide and mRNA electrophoretic patterns highlighted intraspecific
variability.
