Figure 4From: ArabidopsiseIF2α kinase GCN2 is essential for growth in stress conditions and is activated by woundingThe TOR pathway does not interfere with AtGCN2 activity. Immunoblot analysis of eIF2α phosphorylation in TOR RNAi-silenced (35-7 and 65-1) or TOR-overexpressing (G166 and G548) lines (described in [25]). Seedlings of the different backgrounds were either left untreated (Ø) or starved for branched amino acids using chlorsulfuron (Chlor) for 4 h.Back to article page
