Saline soils seriously affect agricultural production. As the largest symbiosis between plants andsoil microbes, arbuscular mycorrhizal (AM) has been extensively studied on its regulatory role inplant (crop) response to salt stress. Recent years, increasing evidence has demonstrated thatjasmonic acid (JA) plays a crucial role in the symbiosis between plants and AM fungi. However,the action mechanism of JA is less understood. In this study, we used endogenous JA deficientmutant spr2and its wild type (wt) to ...
