Fig. 8From: Metabolic alterations provide insights into Stylosanthes roots responding to phosphorus deficiencyExpression analysis of candidate key genes associated with flavonoid metabolism in stylo roots at low P stress. The expression of 12 genes were analyzed in roots of stylo at +Pi and -Pi treatments for 15 d. Transcript expression levels were normalized using housekeeping gene SgEF1α. Each bar represents the mean of four replicates with SE (n = 4). Asterisks indicate significant differences between +Pi and -Pi treatments in the Student’s t-test (*: P < 0.05, **: 0.001 < P < 0.01, ***: P < 0.001), ns indicates no significant differenceBack to article page
