ANN5 — Cicer arietinum

Summary

CaANN5 (LOC101494031) on chickpea chromosome 8 encodes an annexin family protein containing annexin repeats, with calcium ion binding, 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 or far red light, oxidative stress, heat, cold, salinity, and thirst. The protein localizes to the exocytic vesicle, plant-type cell wall, endoplasmic reticulum, plasmodesma, membrane, mitochondria, cytosol, plasmalemma, and cytoplasm. CaANN5 is linked to pollen tube growth, pollen germination, pollen membrane integrity, pollen development, embryo development, flowering time, vegetative to reproductive transition, and plant growth. Studies of related genes in other species connect the annexin family to abiotic stress response.
