Abstract

Organisms removed from their wild environment that are subjected to long term laboratory conditions can experience drastic change. We have specifically used Sinorhizobium meliloti as a model bacterium to address this topic. If soil bacteria containing large genomes necessary to survive in nutrient deficient and stressful conditions were suddenly subjected to nutrient rich and luxurious conditions for 2,500 generations, would they lose some survival based function? We hypothesize that without natural environmental stress, these bacteria would lose the metabolic flexibility previously required for survival resulting in large scale genome reduction.
