Fig. 4From: Comparative metabolite profiling of drought stress in roots and leaves of seven Triticeae speciesLeaf (a) and root (b) metabolites involved in the primary pathways in of Triticeae and its wild relatives under the drought stress. The significant (P < 0.05) and highly significant (P < 0.01) up-regulated metabolites were indicated in red and blue circles, respectively.
