**5. Concluding remarks**

In the past few decades, salt stress in plants has been widely studied in many crops. As oilseed *Brassica* is an important oil crop, therefore, the production of this crops in the salt-affected areas should be explored. There are numerous genotypes of *Brassica* available globally. Therefore, screening the genotypes would be a very first line of work by breeders and plant biologists. As a model plant, *Arabidopsis* has been widely studied by researchers and many salt tolerance traits have been revealed. Moreover, genetic and molecular bases of salt stress tolerance is underway. Salt stress-induced

overgeneration of ROS and subsequent oxidative stress is a common phenomenon in any plants. Understanding the basis of antioxidant defense including ROS signaling and other signaling cascade should be fine-tuned in the light of plant responses to salt stress. Moreover, the approaches should be applicable in the field. Recently, exogenous application of biostimulants, phytohormones, plant nutrients, and many stress elicitors has been researched and applied on the oilseed *Brassica* plants to enhance salt tolerance. However, their appropriate doses and application methods should be finetuned. An integrated approach involving agronomy, plant physiology, and genetics is needed to avail such outcomes.
