ER1 — Pisum sativum

Summary

PSAT7G013960 (ER1, also known as PsLRX3, LRX3, LRX4, LRX5) on garden pea chromosome 7LG7 encodes a leucine-rich repeat extensin-like regulator with transmembrane receptor protein kinase activity, structural cell wall constituent, and peptide, steroid, SNARE, and ATP binding functions. The gene is associated with cell wall composition, plant growth, and salt tolerance, as well as regulation of floral meristem size, floral organ development, specification of floral organ number, anther wall tapetum development, megasporogenesis, microsporogenesis, sporulation, gametophyte development, microtubule bundling, skotomorphogenesis, detection of brassinosteroid stimulus, heat acclimation, and response to other organisms. The product localizes to the plant-type cell wall, plasmalemma, plasmodesma, endosome, secretory vesicle, and extracellular region. Related genes in other species are linked to cell wall integrity and salt hypersensitivity.
