ANN4 — Cicer arietinum

Summary

CaANN4 (LOC101506580) on chickpea chromosome 7 encodes an annexin family protein with calcium-dependent phospholipid binding, peroxidase activity, and mRNA binding functions. The gene is associated with phloem sucrose unloading, calcium-ion regulated exocytosis, fruit ripening, immune response, and responses to oxidative stress, heat, cold, salinity, and abscisic acid. It localizes to exocytic vesicles, root hair tips, thylakoids, apoplast, cell wall, vacuole, plasmodesmata, chloroplast stroma, and Golgi. CaANN4 is linked to water stress, phototropism, osmotic sensitivity, jasmonic acid content, and nematode susceptibility. Related genes in other species connect the annexin family to salt stress response, uranium accumulation, water stress tolerance, root cell growth, and reactive oxygen species regulation.
