GIN2 — Solanum lycopersicum

Summary

SlGIN2 (SOLYC12G008510.2) encodes a hexokinase with glucokinase, fructokinase, and SUMO transferase activities, and also has DNA binding transcription factor activity. It is associated with hexose metabolism, glucose 6-phosphate metabolism, carbon catabolite repression, and downregulation of photosynthesis. The gene has been linked to flower number, anther development, seed viability, and flower abscission in tomato. Associations include fruit fresh weight, fruit dry weight, fruit volume, fruit firmness, starch content, sucrose content, glucose content, flavonoid content, net photosynthetic rate, quantum yield, carbon isotope discrimination, leaf and stem traits, root number, shoot branching, pollen fertility, and gibberellic acid and cytokinin sensitivity. Studies of related genes in other species link the family to drought tolerance, water-use efficiency, leaf senescence, stomatal closure, and photosynthesis.
