520 |a Numerous studies have demonstrated the function of salinity or jasmonic acid (JA) in plant growth and senescence. This study evaluated how the combination of salinity and methyl jasmonate (MeJA) (SaM) worked as a novel stress and then regulated plant growth in Arabidopsis. Firstly, we found that compared with MeJA or NaCl treatment alone, SaM would significantly intensified plant growth inhibition and senescence in wild-type (WT) seedlings, and these phenotypes could be partially compromised after SaM stress in JA-insensitive mutants. Meanwhile, genes involved in JA signaling and Senescence Associated Gene 13 (SAG13) were dramatically increased by SaM stress than that by MeJA or NaCl alone in WT. Moreover, a group of secondary metabolite - indolic glucosinolates (IGs) showed obvious over-accumulation after SaM treatment than that after each single one in WT, and the seedlings treated with IGs' metabolites performed similar inhibited growth and chlorotic leaves phenotypes compared with those caused by SaM stress. All these indicated the toxicity of IGs and their metabolites would prevent the growth progress of plants. Therefore, we concluded that SaM worked as a novel stress and intensified plant growth inhibition and senescence, which was dependent on JA-dependent and -independent signaling pathways
