Defensive symbioses likely arose from host-symbiont interactions that are costly for hosts and evolved over time to a facultative mutualism. Hence, the role symbionts play in protecting hosts against ...

Rhizobial symbiosis refers to the mutually beneficial relationship that forms between plants and soil bacteria that fix nitrogen, termed rhizobia. This study describes ultrastructural changes and ...
