Salicylic acid (SA) is a phenolic compound involved in many aspects of plant growth and development. Apart from its role in biotic interactions, it is also involved in the regulation of important plant physiological processes, including plant water relations under stressful conditions. However, despite the importance of SA in plant physiology, little is known about its effect on AM colonization.
So, can anyone tell me what is the relationship between mycorrhizal symbiosis and salicylic acid levels in plants?
