Abstract The almond crop has high economic importance on a global scale, but its sensitivity to salinity stress can cause severe yield losses. Salt-tolerant rootstocks are vital for feasibility under saline conditions. Two commercial submitted salinity, and evaluated through different parameters, had contrasting results with the survival rates of 90.6% ‘Rootpac 40’ (tolerant) 38.9% ‘Nemaguard’ (sensitive) (Electrical conductivity water = 3 dS m −1 ). Under accumulated less Na Cl more K in leaves than ‘Nemaguard’. Increased proline accumulation indicated that it was highly stressed by compared 40’. RNA-Seq analysis revealed higher degree differential gene expression controlled genotype rather treatment. Differentially expressed genes (DEGs) provided insight into regulation tolerance Prunus . DEGs associated signaling pathways transporters may play essential roles Some additional players involved include CBL10 , AKT1 KUP8 Prupe.3G053200 (chloride channel), Prupe.7G202700 (mechanosensitive ion channel). Genetic components identified this study be explored develop new suitable salinity-affected regions.
