| Abstract: | Soil salinity is a major abiotic stress in plant agriculture worldwide. To engineer salinity-tolerant plants, it is crucial to elucidate the molecular mechanisms of salt-tolerance. Here we reviewed stress sensing and signaling components, as well as key Na^＋ transport and detoxi fi cation pathways in the plant salinity stress response. In addition, we described current knowledge of epigenetic chromatin modifi cations in salinity tolerance response. We also discussed progress in genetic engineering salt tolerance of crops. |
