Long viewed as the exception, symbiosis regarded as a meta-regulation of genotypes to achieve  distinctive traits is becoming a recognised key to respond to environmental changes in an effective way.

SymAction focus on how biotic and abiotic constrains promote symbiosis and on how they function:

- factors promoting symbiosis

- mechanisms determining the formation and establishment of symbioses

- plant microbiomes (including AMF and nitrogen fixers)

- the establishment of a scientific network aiming at identifying the communalities of symbiosis across the distinct symbiotic systems.
