Fig. 4From: Integrated physiological, metabolomic, and transcriptomic analyses elucidate the regulation mechanisms of lignin synthesis under osmotic stress in alfalfa leaf (Medicago sativa L.)Differentially expressed structural genes identified related to the lignin synthesis in alfalfa leaves under osmotic stress. The red arrows represent upregulation and the blue arrows represent downregulation, respectively. The asterisk indicates DEGs with a|log2-fold change| > 1 and P < 0.05Back to article page
