ER1 — Medicago truncatula

Summary

MTR_8G036920, also known as ER1, MtLRR, or DRT100, encodes a leucine-rich repeat (LRR) domain-containing protein with transmembrane receptor serine/threonine kinase activity and nucleotide binding. This barrel medic gene on chromosome 8 is associated with diverse biological processes including innate immune response signaling, nitrogen fixation, UV protection, stomatal complex morphogenesis, lateral root development, organogenesis, and regulation of meristem development. It has been linked to traits such as stomatal resistance, root length, and salinity tolerance, as well as phenotypes involving DNA damage repair. The encoded protein localizes to the membrane, plasmalemma, and apoplast. Studies of related genes in other species connect the family to additional traits including drought tolerance, seed weight, seed size, chlorophyll content, and days to flowering.
