CAL1 — Beta vulgaris subsp. vulgaris

Summary

BvCAL1 (BVRB_4G076780) on sugar beet chromosome 4 encodes a calreticulin/calnexin family protein with calreticulin/calnexin conserved domains and a concanavalin A-like lectin domain superfamily fold. The gene product is associated with calcium ion homeostasis, calcium transport, and the ERAD pathway, and is localized to the endoplasmic reticulum lumen and membrane. It is linked to ethylene signaling, including detection of ethylene stimulus and both upregulation and downregulation of ethylene-mediated pathways, as well as jasmonic acid/ethylene-dependent systemic resistance. Associations include yield and seed yield traits, seedling development, seed dormancy, pollen exine formation and tube development, anther wall tapetum differentiation, anthocyanin metabolism, cytokinin metabolism, H2O2 biosynthesis, and responses to viruses, aphids, temperature stress, and osmotic stress. The product also shows connections to brassinosteroid content and sensitivity, auxin sensitivity, and sulfur and herbicide sensitivity.
