  1. Fold changes under different N conditions were presented: sufficient N vs. limiting N (fold, limiting); sufficient N vs. stress N (fold, stress); stress N vs. 2 hr induction (fold, 2 hr); stress N vs. 24 hr induction (fold, 24 hr). Negative number means gene expression down-regulated in said condition, and positive number means gene expression up-regulated in said condition. ns – not significant from our SAM analysis
