Fig. S1 Stress tolerance of transgenic plants over-expressing OsERFs during the vegetative stage. T1 transgenic plants and NT controls were grown in a greenhouse for four weeks. The plants were subjected to 7 days of drought stress followed by rehydration in a greenhouse. (a) Drought-stress tolerance test of T1 transgenic plants. (b) Drought-stress tolerance of T1 OsERF4a and OsERF10a over-expressing transgenic plants. W, well-watered; D, drought-stressed and rehydrated. Photographs were taken on the indicated days

Fig. S2 Genomic Southern blotting analyses of OsCc1:OsERF4a (a), Ai:OsERF4a (b) and OsCc1:OsERF10a (c) plants. Ten micrograms of genomic DNA was double-digested with EcoRI and XhoI restriction enzymes, separated on a 0.8% agarose gel, blotted onto a membrane, and hybridized with a 32P-labeled MAR probe
