Phase variation in Myxococcus xanthus yields cells specialized for iron sequestration.

Abstract excerpt

Myxococcus xanthus undergoes phase variation during growth to produce predominantly two colony phenotypes. The majority are yellow colonies containing swarm-proficient cells and a minority are tan colonies containing swarm-deficient cells. Comparison of the transcriptomes of a yellow variant, a tan variant, and three tan mutants led to the identification of differentially-regulated genes that define key segments...
