Fig. 1From: Integrated physiological, metabolomic, and transcriptomic analyses elucidate the regulation mechanisms of lignin synthesis under osmotic stress in alfalfa leaf (Medicago sativa L.)The changes of osmotic potential (A), relative water content (B), and lignin content (C) in the leaf tissue of alfalfa under osmotic stress. Data were presented as the mean standard deviation (SD). Different letters (a, b, and c) indicate significant differences (P < 0.05)Back to article page
