TL;DR: It is argued that the strategy of rice breeding for better Na+ exclusion employed for the last few decades has reached a plateau and cannot deliver any further improvement in salinity tolerance in this species, and calls for a paradigm shift in rice breeding and more efforts toward targeting mechanisms of the tissue tolerance.

TL;DR: The role of HKT1;5 in plant salinity tolerance cannot be attributed to merely reducing Na+ concentration in the xylem sap but triggers a complex feedback regulation of activities of other transporters involved in the maintenance of plant ionic homeostasis and signaling under stress conditions.

TL;DR: It was found that K+ retention and low recovery Cl− efflux in mesophyll cells confers salt tolerance in rice, which will provide guidance to examine crop salinity tolerance at reproductive stages in controlled environments and natural climatic conditions in the future.

TL;DR: In this paper, the salinity tolerance of wild rice Oryza rufipogon from early vegetative stage to maturity was investigated and shown to be a potential donor for breeding salinity tolerant traits in rice.
