RNA-Seq of Streptomyces venezuelae NRRL B65442 to compare global gene expression between the wild-type and bldB deletion strain and, wild-type and bldB plus whiJ9 double mutant after 14 hours growth in liquid medium.
Expression of iosA is greatly activated in the bldB deletion strain. whiJ9 is divergently transcribed from iosA and the double mutant (whiJ9 + bldB) was made to determine if WhiJ mediates the activation of iosA in the absence of BldB.
