ATDI8 — Arabidopsis thaliana

Summary

AT5G66400 (ATDI8, RAB18) on chromosome 5 of Arabidopsis thaliana encodes a dehydrin-family protein with a Dehydrin_CS domain and metal-binding capabilities, including nickel and copper binding. The gene is directly associated with drought response, and its product localizes to the membrane, cytosol, cytoplasm, and nucleus. It is linked to abscisic acid homeostasis, the xanthophyll cycle, membrane depolarization, and responses to water, salt, and cold stress. Associations also include traits such as transpiration rate, stomatal resistance and opening, photosynthetic rate, seed dormancy, germination rate, root length, and calcium concentration. Studies of related genes in other species connect the family to drought and salt tolerance, osmotic stress response, and traits including water use efficiency, chlorophyll content, and seed size.
