Abstract: Among abiotic stresses, salinity is the most important factor causing loss of yield after drought. As a result of global warming, chemical fertilizers, pesticides, and environmental pollution caused by anthropogenic activities, the salinity of the soil increases. Plants are developing evolutionary adaptations to deal with stresses. In this study, the contribution of vanilla to wheat defense mechanism against salt stress was evaluated. Genetic change in 0, 3, 6, g / l, 9, 12 and 15 g / l salt-related and salt stress and vanillacetone was used by molecular tests. The average of polymorphism value formed by Inter Retrotransposon Amplified Polymorphism (IRAP) analysis is determined as 31.28 %. In these examples, the realization of the Genomic Template Stability (GTS) value was 68.72 %. In addition to salt stress, the average polymorphism of the applied samples of vanilla was determined as 26.89 % and the average of the GTS value was 73.11 %. The results of gene expression analysis indicate that the level of gene expression decreases in the samples where salt stress and vanillae are applied compared to the samples exposed to salt stress. It was determined from the study results that vanillae relieves salt stress in wheat and contributes to defense regulation.
