Summary of relative expression patterns of NADK genes in nine plant species, including Arabidopsis thaliana, Solanum lycopersicum, Glycine max, Medicago truncatula, Oryza sativa, Hordeum vulgare, Zea mays, Sorghum bicolor and Triticum aestivum. Expression profiles of nine NADK family genes in different developmental stages and tissues were obtained from the microarray and mRNA sequencing data in Genevestigator (Figures S1, S2). •, weak expression; ••, moderate expression; •••, strong expression; NA, not available.
