Dynamic control of lipid provisioning in plant–fungal symbiosis

Arbuscular mycorrhizal (AM) fungi form a type of endomycorrhiza that helps plants capture nutrients from the soil. Lipid provisioning plays a critical role in maintaining the AM fungi within the plant cortical cells during AM symbiosis. The coordination of lipid provisioning with AM symbiosis is regulated by the lysin motif (LysM) and leucine-rich repeat receptor-like kinases (RLKs), including DOES NOT MAKE INFECTIONS 2 (DMI2), through transcriptional programming (Shi et al., 2023). However, key components of the complete signaling pathway remain to be identified.
