Germination and growth of <i>F. verticillioides</i> wild-type (WT), Δsda1, sdaC, and sdaT strains.

<p>A total of 10⁵ spores were inoculated and incubated in DL media with sorbitol at 25°C for (A) 16 h and (B) 40 h. (A) Note the lack of germination of the Δsda1 strain. (B) After 24 h of incubation in DL media with sorbitol, 2% w/v of glucose was added to the cultures. Note the germination of the Δsda1 strain in the presence of glucose vs. sorbitol. Scale bar = 5 µm.
