**6. Conclusions and prospects**

Recently, advanced research has focused on unraveling the genetic and molecular mechanisms of BR and auxin pathways in plants responses to salt stress. BR plays a crucial role in promoting responses to salt stress, by activating a family of transcription factors BZR1/BES1 which can directly or indirectly regulate the expression of BR-responsive genes. It can ultimately affect not only development and growth of plants but also auxin biosynthesis and signaling. The interplay between auxin and BR pathways has been shown to be crucial in multiple plant development processes

under salt stress including hypocotyl elongation, root development, halotropism and gravitropism. Future thorough studies are required to fully understand the interdependency between auxin and BR in improving salt stress tolerance before implementing new approaches to engineer stress resilient crops.
