Fig. 6From: Comprehensive dissection of transcript and metabolite shifts during seed germination and post-germination stages in poplarProfiling of primary metabolites and genes related to seed germination and post-germination processes. a Primary metabolite profiling of seed germination and post-germination processes. Asterisks indicate significant differences (red: significantly up-regulated; blue: significantly down-regulated). b Primary metabolism-related gene profiling of seed germination and post-germination processes. Expressions: blue, minimum; yellow, maximum. See also Additional file 8: Table S8 and Additional file 9: Table S9Back to article page
