ANN5 — Cicer arietinum

Summary

CaANN5 (LOC101508627) on chickpea chromosome 4 encodes an annexin family protein with annexin repeats, calcium-dependent phospholipid binding, phosphatidylserine binding, F-actin binding, and structural constituent of cytoskeleton activities. It is associated with calcium-ion regulated exocytosis, protein trimerization, regulation of cellulose anabolism, cytoskeleton organization, secretion, developmental growth, fruit ripening, and responses to red/far-red light, oxidative stress, heat, cold, salinity, and thirst. The protein localizes to exocytic vesicles, the cytoskeleton, plant-type cell wall, ER, plasmodesmata, membrane, mitochondria, cytosol, plasmalemma, and cytoplasm. CaANN5 has been connected to pollen tube growth, pollen germination, pollen membrane integrity, pollen development, embryo development, flowering time, vegetative to reproductive transition, chilling tolerance, root hair elongation, and plant growth. Studies of related genes in other species link the family to abiotic stress response and vegetative to reproductive phase transition traits.
