Abstract: Soybean is an important cash crop that is being affected by the problem of soil salinity.Understanding the genetic and molecular mechanisms of salt tolerance will no doubt facilitate the process of overcoming this problem.Sequencing of both the cultivated soybean (Glycine max) genome and the wild soybean (Glycine soja) genome greatly promoted the development of omics research.Up to now,genomics,transcriptomics,proteomics and metabolomics are all currently used to provide large amounts of data that can help us further understand the salt-tolerance mechanism of the soybean.This paper aims to summarize recent publications applying omics techniques to probe into the detailed mechanisms of soybean salt tolerance.
