Abstract
Thein vitro activity of glutamate dehydrogenase (NADH-GDH), from dark-treated root segments of maize seedlings responded differently to amino acids threonine, glutamate and methionine than that from light-treated root segments, and to the amino acid methionine in dark- and light-treated shoot segments. In most cases amino acids inhibited GDH activity, the inhibition increased with amino acid concentration. However, methionine activated GDH from dark-treated roots and light-treated shoots, while aspartate had little effect on enzyme activity.
