GDH1 — Brachypodium distachyon

Summary

BdGDH1 (BRADI_1G05680V3) on chromosome 1 encodes a glutamate dehydrogenase with NAD(P)+ activity, capable of binding nucleotides, copper, zinc, and cobalt ions. The enzyme is associated with glutamate breakdown, nitrogen utilization and response to nitrogen compounds, cellular response to nitrogen starvation, TCA cycle, primary and secondary metabolism, lignin anabolism, homeostasis, syngamy, and responses to cold, salinity, basic pH, and absence of light. It is linked to photosynthetic rate, respiration rate, nitrogen assimilation, leaf senescence, chlorophyll degradation, nutrient remobilization, seedling growth, anoxia and low-oxygen tolerance, carbon starvation tolerance, thermal stability, and redox response. The protein localizes to mitochondria, plastid, cytosol, vacuole, and plasmalemma. Studies of related genes in other species connect the family to grain yield, grain weight, root traits, nitrogen and chlorophyll content, and salt and cold tolerance.
