GIN2 — Arabidopsis thaliana

Summary

AT4G29130, also known as GIN2 or HXK1, encodes a hexokinase enzyme with glucokinase and fructokinase activities, and is annotated with core promoter sequence-specific DNA binding, F-actin binding, and SUMO transferase activity. In Arabidopsis, this gene is associated with glucose signaling, photosynthesis, drought tolerance, stomatal closure, leaf senescence, growth, and transpiration. It is linked to hexose metabolism, cell glucose homeostasis, hexokinase-dependent signaling, actin filament capping, cytoplasmic streaming, and energy homeostasis. The gene has been connected to traits including glucose content, starch mobilization, photosynthetic rate, transpiration rate, fruit weight, seed dormancy, and sensitivities to gibberellic acid, cytokinin, ethylene, and auxin. Studies of related genes in other species link the family to flower number, fruit size, anther development, and water-use efficiency.
