Abstract

Nicotinamide adenine dinucleotides (NAD(H)) and NAD phosphates (NADP(H)) are electron carriers involved in redox reactions and metabolic processes in all organisms. NAD kinase (NADK) is the only enzyme that phosphorylates NAD+ into NADP+, using ATP as a phosphate donor. In NADP-dependent malic enzyme (NADP-ME)type C4 photosynthesis, NADP(H) are required for dehydrogenation by NADP-dependent malate dehydrogenase (NADP-MDH) in mesophyll cells, and decarboxylation by NADP-ME in bundle sheath cells. In this study, we identified five NADK genes (FbNADK1a, 1b, 2a, 2b, and 3) from the C4 model species Flaveria bidentis. RNA-Seq database analysis revealed higher transcript abundance in one of the chloroplast-type NADK2 genes of C4 F. bidentis (FbNADK2a). Comparative analysis of NADK activity in leaves of C3, C3-C4, and C4 Flaveria showed that C4 Flaveria (F. bidentis and F. trinervia) had higher NADK activity than the other photosynthetic-types of Flaveria. Taken together, our results suggest that chloroplastic NAD kinase appeared to increase in importance as C3 plants evolved into C4 plants in the genus Flaveria.
