AbstractQuinoa (Chenopodium quinoa Willd.) is an Andean crop, characterized by its excellent nutritional profile and notable tolerance to abiotic stress, such as freezing, draught or salinity. Previous reports (Burrieza et al. 2012) show that plants of the cv. Hualhuas can complete their life cycles and develop viable seeds when treated with 500 mM NaCl during their development. In this study we report the changes in leaf tissues and morphological changes in root, stem and leaves of plants treated in conditions of high salinity as compared to control plants. Likewise, we associated these changes with the differences found in the respective protein profiles. The proteins were identified by a shotgun proteomic study followed by an in silico analysis.
