Expression of PstO genes in Ax2 and the dmtA− mutant lacking DIF. Thirty PstO genes were analyzed by in situ hybridization in both Ax2 and the dmtA− mutant lacking DIF at the slug stage. Among those, 18 genes were down-regulated in the mutant, as exemplified by SSD764 (a and b) and SSM184 (c and d). Although residual expression was detectable in SSM184, SSD764 was totally extinguished. In contrast to these genes, 12 genes were not affected, as exemplified by SLF774 (e and f) and SLA769 (g and h). (a, c, e, and g) Ax2; (b, d, f, and h) dmtA− mutant.
