A scattered array of DNA acquired via horizontal transfer can co-evolve into a well-tuned, efficient genetic network to maximize an organism's fitness, a new linkurl:study;http://www.nature.com/msb/journal/v5/n1/full/msb200940.html finds. Reporting online earlier this month in __Molecular Systems Biology__, researchers showed that a single transcription factor in a tiny, salt-loving archaeon coordinates the expression of more than 100 newly-obtained genes.

M.C. Schmidt, C.C. Kao, R. Pei, A.J. Berk, "Yeast TATA-box transcription factor gene," Proceedings of the National Academy of Sciences, 86, 7785-9, October 1989. Arnold Berk (University of California, Los Angeles): "TFIID binding to a TATA box initiates the ordered assembly of multiple transcription factors (TFs) required for initiation on eukaryotic promoters. However, TFIID resisted purification from higher organisms, preventing detailed studies of the process. We were interested in TFIID be
