CAX1 — Glycine max

Summary

GmCAX1 (GLYMA_12G241200V4) encodes a sodium:hydrogen exchanger, a member of the CPA2 transporter family with cation/H+ exchanger domains. In soybean, this gene is associated with leaf senescence, metabolic burst, post-translational modification, and homeostasis. It has been linked to chlorophyll content, salt tolerance (SALTTL), and a wide range of traits including seed calcium and manganese content, seed germination, plant growth and productivity, vegetative phase change, stomatal regulation and closure, freezing tolerance, submergence and anoxia tolerance, pathogen resistance, defense response, hormone sensitivity, and tolerance to magnesium sulfate and serpentine soils. Studies of related genes in other species connect the family to calcium transport and distribution, salt and metal tolerance, cold acclimation, and abiotic stress responses.
