Most differentially expressed genes among MI and MII with unknown function and conserved in the Streptomyces genus.

Average log2 abundance values and functions as in Table 2. Genes whose function was not characterized, with average log2 relative abundances greater than ±3 in at least one of the developmental phases analyzed (up- or down- regulated by greater than 8-fold in MII at 24, 48 or 72 hours with respect to MI) are shown (see text for details). Only genes with conservation (similarity)>75% among S. coelicolor, S. avermitillis MA-4680, S. griseus, S. clavuligerus ATCC27064 and S. scabies were selected.
