Popis:	Soil salinity markedly suppresses the growth of rice (Oryza sativa L.). We established rice anther culture to select for rice callus lines adapted to NaCl stress and regenerated plant progenies resistant to a NaCl stress of E.C. 16–18 mS. When exposed to NaCl, NaCl-adapted rice calli lost K+ and accumulated little Na+. Conversely, plant cells lost relatively little K+ and accumulated Na+. It is plausible that, NaCl-resistant mechanisms are different at callus and plant level. The stable NaCl-resistant lines produced have potential use in elucidating the molecular mechanisms behind NaCl resistance in rice and in rice breeding.
