Self-generated diversity produces "insurance effects" in biofilm communities.

Proceedings of the National Academy of Sciences of the United States of America - 23 Nov 2004

Boles Blaise R, Thoendel Matthew, Singh Pradeep K

Abstract excerpt

Diversity generally protects communities from unstable environmental conditions. This principle, known as the "insurance hypothesis," has been tested in many different ecosystems. Here we show that the opportunistic pathogen Pseudomonas aeruginosa undergoes extensive genetic diversification during short-term growth in biofilm communities. The induced genetic changes are produced by a recA-dependent mechanism and...
