ANN1 — Glycine max

Summary

GmANN1 (GLYMA_13G088700V4) on soybean chromosome 13 encodes an annexin family protein containing annexin repeats and an AnnexinD_plant domain. The product exhibits calcium-dependent phospholipid binding, peroxidase activity, RNA chaperone function, and calcium ion binding. GmANN1 is associated with seed growth, primary root development, phloem sucrose unloading, cellular respiration, the TCA cycle, and nutrient storage. It localizes to the exocytic vesicle, root hair tip, thylakoid, apoplast, cell wall, and plasmodesmata. The gene is linked to responses to water stress, osmotic stress, high and low temperature, salinity, and abscisic acid, as well as leaf length, phototropism, jasmonic acid content, and nematode susceptibility. Associations include calcium signaling, potassium transport, reactive oxygen species accumulation, and systemic defense against herbivory. Studies of related genes in other species connect the family to freezing tolerance, heat stress tolerance, phototropism, and cold-induced calcium signaling.
