Polar primary metabolites which accumulate at least 2-fold in arbuscule containing cells of mycorrhizal roots (myc+) compared to cortex cells of non-mycorrhizal roots (myc-) of Medicago truncatula. Proteinogenic amino acids (black bars), polyols (grey bars) and disaccharides (light grey bars) are highlighted (cf., Additional file 2: Table S1). Yet non-identified metabolites are named by an identifier code of the GolmMetabolome Database (http://gmd.mpimp-golm.mpg.de/)
