**Abstract**

These genes increase the plant's tolerance to salt stress by producing proteins and metabolites that protect the cell against stress. More secondary metabolites including anthocyanins phenols, saponins, flavonoids, carotenoids, and lignins, etc., are produced by plants in salty conditions, but previous studies have only looked at a small portion of these compounds. Antioxidant activity and phenolic compound accumulation under salt stress have been linked in several studies. Proline accumulates in the cytoplasm and the vacuole, where it functions as an osmolyte and protects macromolecules against denaturation. Polyamines play a role in salt tolerance by regulating gene expression and ion flux. This means that metabolites are crucial for plant response to salt stress and maintaining agricultural productivity in salt-affected environments.
