Two LysM receptor‐like kinases regulate arbuscular mycorrhiza through distinct signaling pathways in Lotus japonicus.

This article explores the role of LysM receptors, specifically LYS6 and LYS7, in regulating arbuscular mycorrhiza (AM) in Lotus japonicus. AM is a beneficial interaction between plants and fungi that aids in nutrient exchange. The study found that LYS7 is upregulated in roots infected with AM fungi, suggesting its involvement in AM. Mutants lacking LYS6 and LYS7 showed reduced colonization and arbuscule formation by AM fungi, highlighting the importance of these receptors in AM regulation. The study also revealed that LYS6 is involved in the expression of AM-induced genes and the induction of calcium spiking. Overall, LYS6 and LYS7, along with their downstream signaling pathways, are crucial for the initial response to AM in Lotus japonicus. [Extracted from the article]
