AM fungi form spores during their life cycle. A spore is distinct from an arbuscule, the exchange structure in a root. Research on fungal reproduction is complex, so a simple product description should not imply that all fungi reproduce or establish in the same way.
Keep the context.
Biological compatibility, successful colonisation and a measurable plant response are different questions. The growing conditions matter, and general research is not a promise of a particular result with MegaMyco.
