From: The interplay between miR156/SPL13 and DFR/WD40–1 regulate drought tolerance in alfalfa
GCMS-based primary metabolite profiling demonstrates drought stress tolerance strategies by miR156. a Relative levels of proteinogenic amino acids in leaf tissues during drought stress: alanine, asparagine, aspartate, glycine, isoleucine, serine, threonine, tryptophan and valine; b relative levels of metabolites from the γ-aminobutyric acid (GABA) shunt in leaf, stem and root tissues of proline, and c GABA; d relative levels of sugars from tissues of leaf, stem and root as fructose, and e arabinose under drought stress. Values are sample means ± SE, n = 4 individual plants. ANOVA p values are provided in Additional file 2: Table S5.5. Significant difference in Post hoc Tukey multiple comparisons test is indicated with different letters
