LRR — Glycine max

Summary

GmLRR (GLYMA_08G152800V4) on soybean chromosome 8 encodes a leucine-rich repeat (LRR) domain-containing protein with receptor serine/threonine kinase activity, ATP binding, and signaling receptor activity. It is associated with diverse biological processes including innate immune response activation, UV protection, chlorophyll breakdown and anabolism, nitrogen fixation, floral organ development, regulation of leaf senescence, and gametophyte development. The gene is linked to agronomically important traits such as seed weight, seed size, pollen fertility, chlorophyll content, root length, and drought tolerance. It localizes to the plasma membrane, endosome, ER membrane, and nucleus. Studies of related genes in other species connect the family to stomatal resistance, photochemical quenching, and days to flowering, though these associations are not yet established in soybean.
