Overview of the differentially expressed genes (DEGs) in leaves of tobacco seedlings in response to different Mg supplies. (A) Number of the up-regulated and down-regulated DEGs in Mg0, Mg1/4, and Mg4 in comparison to Mg1 at 5, 15, and 25 DAT, respectively. (B) Heatmap showing the differential expression levels of the identified DEGs in leaves of tobacco seedlings grown under different Mg supplies at 5, 15, and 25 DAT, respectively. (C) Upset diagram showing the numbers of the DEGs specific or common in leaves of tobacco seedlings grown under different Mg supplies at 5, 15, and 25 DAT, respectively. Mg0, 0 mM Mg; Mg1/4, 0.50 mM Mg; Mg1, 1.99 mM Mg; Mg4, 7.96 mM Mg.
