NFP — Medicago truncatula

Summary

MTR_3G080170 (NFP, also known as MtLYK5) in barrel medic (Medicago truncatula) on chromosome 3 encodes a dual-specificity protein kinase with transmembrane receptor activity, belonging to the LysM receptor-like kinase family. It is associated with chitin and chitosan binding, cellular responses to chitin and bacterial molecules, and pattern-recognition receptor signaling. The gene is linked to root hair tip growth and elongation, auxin transport, organogenesis, hyphopodium formation, spore germination, regulation of oxidative stress and hydrogen peroxide metabolism, and salinity response. Associations with agronomically relevant traits include fruit weight, plant height, leaf number, bacterial blight disease resistance, stomatal closure, and tolerance to salinity and fungal pathogens such as Botrytis cinerea and Fusarium graminearum. Studies of related genes in other species connect the family to chitin signaling, innate immunity, and thermotolerance.
