NAD kinase activity in wheat leaves under water deficit.
Total NAD kinase activity remained unaltered in the drought non-adapted wheat leaves under water deficit, but gradually decreased with water deficit in the adapted ones. The share of the calmodulin-dependent enzyme was significantly higher in the drought-hardened than in non-hardened plants; however, under severe water deficit the activity of the enzyme dropped by half. It seems, therefore, that NAD kinase activity does not limit phosphorylation of NAD in dehydrated plant tissues.
