Periodic selection in longterm continuous-flow cultures of the filamentous fungus Fusarium graminearum.

Abstract excerpt

By monitoring increases and decreases in the proportion of cycloheximide-resistant macroconidia, periodic selection was observed in populations of the filamentous fungus Fusarium graminearum, grown in glucose-limited chemostat cultures. The results indicated that periodic selection of advantageous mutants of F. graminearum occurred at intervals of about 124 h at both high (D = 0.19 h-1, approximately 34...
