Arbuscular mycorrhizal fungi form beneficial partnerships with grapevine roots, helping plants absorb water and nutrients while improving stress tolerance. These fungi relationships begin in plant nurseries and continue in vineyards, but their effectiveness depends on the specific fungus species, vine variety, and farming practices like soil management and herbicide use. Using these fungi as biological stimulants could help grapevines cope with climate change challenges like drought and heat, though more field studies are needed to confirm their practical benefits.
