Entering into a symbiotic relationship is not something to be taken lightly. Previously free-living organisms become beholden to each other and have to tolerate invasion of their personal space to accommodate varying degrees of intimacy, especially when one partner lives within the body or even the cells of the other. Symbiosis brings with it so many potential mutual benefits that it has arisen...
The Gram-negative soil bacteria of the family Rhizobiaceae can fonn nodules on the roots of leguminous plants and as a result are able to fix nitrogen. This partnership is highly specific as particular legumes are generally infected by one rhizobial species only (for example alfalfa by R. meliloti and soybean by B. japonicum'i. The establishment of the symbiosis is a multistepped, interactive p...
In many bacteria, the twin arginine translocation (Tat) system transports folded proteins across the cytoplasmic membrane, and these proteins can play a role in symbiotic or pathogenic infections. A role for the Vibrio fischeri Tat system was identified during symbiotic colonization of its host Euprymna scolopes, demonstrating a function for the Tat system in host colonization by a member of th...
Sponges and bacteria have lived together in complex consortia for 700 million years. As filter feeders, sponges prey on bacteria. Nevertheless, some bacteria are associated with sponges in symbiotic relationships. To enable this association, sponges and bacteria are likely to have developed molecular communication systems. These may include molecules such as N-acyl-L-homoserine lactones, produc...
