GDH — Sorghum bicolor
Summary
SORBI_3003G188400 (GDH) on sorghum chromosome 3 encodes a glutamate dehydrogenase with both NAD⁺ and NADP⁺ activity (EC 1.4.1.4). The gene is associated with glutamate breakdown, response to nitrogen compounds, nitrogen starvation, and basic pH stress, as well as with salinity and cold responses. The product localises to mitochondria, the mitochondrial lumen, and the cytosol. GDH has been linked to photosynthetic rate and chlorophyll content. Studies of related genes in other species connect the family to traits including nitrogen content, soluble protein and sugar levels, leaf senescence, germination rate, tiller number, root growth, and tolerance to drought and cold.
