The evolution of gene regulation: How microbial neighbors settle differences

Supply and demand could be a governing principle even at the genetic level, because most genes are only expressed when needed. Biologists at the Ludwigs-Maximilians-Universitat in Munich, Germany, show that in microbes evolutionary factors determine which regulation mechanism will regulate a given gene.
