Figure 2. Stability of SOS1 mRNA is enhanced by H2O2 treatment.

Figure 2

(a) SOS1 transcript levels in 35S:SOS1 transgenic plants after treatment with H2O2 or plant growth regulators. H2O2, 10 mm H2O2; ACC, 10 µm 1-aminocyclopropane-1-carboxylic acid (ACC); Ethylene, 100 µl l−1 ethylene gas; JA, 100 µm methyl jasmonate; SA, 0.3 mm salicylic acid.

(b) The H2O2-induced stability of SOS1 mRNA is concentration dependent and the induction is rapid. SOS1 transcripts were detected in the 35S:SOS1 transgenic plants.

(c) The native SOS1 transcript level is also increased by H2O2 treatments.

(d) Salt and dehydration stress treatments promote the production of ROS in Arabidopsis seedlings. The stress treatments are the same as stated in Figure 1e.
