Genome-wide identification of target genes of a mating-type α-domain transcription factor reveals functions beyond sexual development.

abstract：:Bacterial biofilms contain subpopulations of cells that are dormant and highly tolerant to antibiotics. While dormant, the bacteria must maintain the integrity of macromolecules required for resuscitation.
