GIN2 — Solanum tuberosum

Summary

PGSC0003DMG400016521, also known as GIN2, HXK2, or StHXK1 on potato chromosome 6, encodes a hexokinase with glucokinase, fructokinase, and SUMO transferase activities, and it binds F-actin, DNA, and ATP. The gene is associated with hexose metabolism, glycolysis, glucose-mediated signaling, starch anabolism, and actin filament dynamics. It has been linked to traits including photosynthetic rate, transpiration rate, stomatal opening and resistance, leaf and root development, shoot branching, flowering time, fruit weight, and responses to oxidative stress, ethylene, auxin, and cytokinin. Phenotypic associations include glucose tolerance, seed germination, pollen viability, lateral root formation, plant growth, leaf senescence, and programmed cell death. Studies of related genes in other species link the family to drought tolerance, water-use efficiency, stomatal closure, leaf senescence, and immune response.
