The experiments were used to detect proteins in ethylene regulated salt response in quinoa. The quinoa is one of healthy food source for human. Ethylene is a stress hormone, which improves salt tolerance in plants by regulating adaptive changes in gene expression level. Proteomic analysis provides an efficient method to excavate downstream functional genes in a large scale. In order to clarify the ethylene regulated salt response pathway in quinoa, the whole seedlings of 4-week-old quinoa treated with water, salt, salt and ethylene precuorsor ACC, respectively, and analyzed by proteomic analysis in this research.
