Fig. 4

A comparison of fold changes of the metabolites in molecular level associated with the stressed conditions. The boxes show the log twofold changes and the letters of a, b, c, d and e above the boxes represent the comparisons of +N+EL/+N, −N/+N, −N+Ses/−N, +N+DCMU/+N and −N+EL/−N, respectively. The carbon flux can be regulated by N-starvation and EL. The carbon metabolites: G6P glucose-6-phosphate, F6P fructose-6-phosphate, 6PG 6-Phosphogluconic acid, G3P glyceraldehyde-3-phosphate, 3PG 3-phosphoglycerate, PYR pyruvate, OAA oxaloacetate, MAL malate, FUM fumarate, SUC succinate, 2OG 2-oxoglutarate, CIT citrate, GLU glutamate
