Review: Plant signaling and metabolic pathways enabling arbuscular mycorrhizal symbiosis ($)

The relationship between plants and arbuscular mycorrhizal fungi has persisted for 400 million years, but we are still learning about the biochemistry of this interaction. MacLean, Bravo and Harrison review how plants attract, recognize, and accommodate their fungal partners, from pre-contact through nutrient exchange. Recent insights including the role of the NOPE1 N-acetylglucosamine transporter in maize and rice, and the transfer of fatty acids from plant to fungus are also discussed. Plant Cell
