Figure 3. There is a delay between expression of the antimycin biosynthetic genes and the production of antimycins.

(A) HPLC analysis of metabolites produced by S. albus S4 wild-type. Antimycins are detected in media extracts of 42 h old but not 18 h old cultures. (B) qRT-PCR analysis of the antimycin gene cluster in 18 and 42 h old cultures shows that expression of the antimycin gene cluster is significantly down-regulated following differentiation. *** denote that values reported are statistically significantly different with a P value < 0.001 in a Student’s T-test.
