| Abstrakt: |
Autonomous secondary colonies are formed on the primary colonies of Fusarium bulbigenum var. blasticola grown in a synthetic Rieder medium. The secondary colonies are similar to genuine neoplasia in the following characteristics: dedifferentiation of the mycelium filamentous structure to yield single yeast-like cells, selective growth, faulty differentiation. Just as antioxidants and respiration substrates inhibit tumour formation and growth in higher organisms, they either prevent or inhibit the formation of secondary colonies in microorganisms. In contrast, their formation is stimulated when prooxidants and respiration inhibitors are added to the growth medium. |
