Summary of the key metabolic pathways in low light and salt stress response in sheepgrass. A, Venn diagram of differentially abundant metabolites in comparisons of salt and light treatments. B, Heatmap representing the relative abundance of overlapped differentially abundant metabolites in comparisons of light (ML_0 vs. LL_0) and salt (ML_200 vs. ML_0 & ML_50 vs. ML_0). C-E, Relative expression levels of genes involved in ABA signaling pathway, photorespiration, and GSH/GSSG redox system pathways in sheepgrass leaves exposed to either LL or salt treatments. F, Summary of regulation pattern of key metabolic pathways in response to low light and salt stress in sheepgrass leaves. G, Working model showing the interactive effects of LL and salt on key metabolic pathways in sheepgrass leaves
