Salinization of soil is increasing with a perspective to lose arable lands. The presence of salt in the soil can damage seriously the crops, causing considerable losses in their yields. To solve this critical issue, the improvement of the knowledge about the response mechanism in plants exposed to salinity is necessary to better select tolerant genotypes that can be used in breeding programs. This paper recapitulates some aspects of plant response to salinity and the current perspective in solving the problem related to the improvement of plant tolerance to salinity. An overview of salt tolerance studies in Brassica is presented.
