|a Seed germination is the first step of seedling establishment, which is particularly sensitive to drought stress. Elucidating the mechanism regulating seed germination under drought stress is of great importance. We showed that overexpressing Tomato Ethylene Responsive Factor 1 (TERF1), an ERF transcription factor in the ethylene signaling pathway, significantly reduced seed sensitivity to mannitol treatment during seed germination. Germination assay demonstrated that TERF1 could activate gibberellin acid (GA) signaling pathway independent on GA metabolism during germination. By comparative transcriptome analysis (mannitol vs normal germination condition, mannitol vs mannitol plus paclobutrazol (PAC, an inhibitor of GA biosynthesis)) we identified the genes regulated by TERF1 specifically under mannitol treatment and confirmed that TERF1 could activate GA signaling pathway independent on GA metabolism, which were consistent with the germination assay with mannitol and mannitol plus PAC treatment. Based on sugar, gene expression and germination analysis we proved that TERF1 promoted seed germination through glucose signaling pathway mediated by GA. Thus our study provides an underlying mechanism for activating GA signaling pathway by TERF1 during seed germination under osmotic conditions
