The overall goal of research in the Rosenzweig lab is to elucidate mechanisms that produce and maintain diversity in prokaryotic and eukaryotic microbes. We are particularly interested in understanding how changes in genome architecture affect global patterns of gene expression and whether such changes translate into how clones behave physiologically and demographically. We are engaged in several projects related to this theme: we are investigating how yeast and bacterial genomes, including those of interspecific hybrids, respond to either chronic resource limitation or continuously changing temperature and ethanol regimes. We are now also studying how genome architecture of opportunistic pathogens evolves in the cystic fibrosis lung. In the lab and in nature it is possible to track evolution of clonal microbial populations for hundreds of generations. A living record of each population’s evolutionary trajectory can be preserved by archiving samples as -80°C glycerol stocks, and the tempo of evolutionary change inferred from changes in the frequency of neutral markers. The physiology and genetics of evolved strains and their ancestors can then be analyzed in detail to determine the bases for differences in Darwinian fitness. Sequencing of the yeast, E. coli and P. aeruginosa genomes makes possible the use of DNA microarrays to assess how changes in genome architecture and transcript levels underlie, or attend, evolutionary adaptation to various selection pressures.
