GDH — Capsicum annuum
Summary
CaDHE4 (GDH, T459_02680) on pepper chromosome 1 encodes a glutamate dehydrogenase (NADP(+)) with both NAD⁺- and NADP⁺-dependent L-glutamate dehydrogenase activity (EC 1.4.1.4). The gene is associated with glutamate breakdown, amino acid metabolism, and responses to nitrogen compounds, nitrogen starvation, cold, salinity, and basic pH. It is linked to nonphotochemical quenching, chlorophyll fluorescence, and photosynthesis. The product localises to mitochondria and cytosol. Associations with agronomic traits include root nitrogen content, plant dry weight, leaf water potential, fruit weight, photosynthetic rate, photochemical quenching, respiration rate, and drought tolerance. Studies of related genes in other species connect the family to leaf nitrogen, nitrate, soluble protein, proline, starch, and carotenoid content, as well as root and shoot dry weight, plant height, water use efficiency, and cadmium concentration.
