Key message Sustaining yield gains of grain legume crops under growing salt-stressed conditions demands a thorough
understanding of plant salinity response and more efficient breeding techniques that effectively integrate modern
omics knowledge.
Abstract Grain legume crops are important to global food security being an affordable source of dietary protein and essential mineral nutrients to human population, especially in the developing countries. The global productivity of grain legume
crops is severely challenged by the salinity stress particularly in the face of changing climates coupled with injudicious use
of irrigation water and improper agricultural land management. Plants adapt to sustain under salinity-challenged conditions
through evoking complex molecular mechanisms. Elucidating the underlying complex mechanisms remains pivotal to our
knowledge about plant salinity response. Improving salinity tolerance of plants demand enriching cultivated gene pool of
grain legume crops through capitalizing on ‘adaptive traits’ that contribute to salinity stress tolerance. Here, we review the
current progress in understanding the genetic makeup of salinity tolerance and highlight the role of germplasm resources and
omics advances in improving salt tolerance of grain legumes. In parallel, scope of next generation phenotyping platforms
that efficiently bridge the phenotyping–genotyping gap and latest research advances including epigenetics is also discussed
in context to salt stress tolerance. Breeding salt-tolerant cultivars of grain legumes will require an integrated “omics-assisted”
approach enabling accelerated improvement of salt-tolerance traits in crop breeding programs.
