Comparing salt-induced responses at the transcript level in a salares and coastal-lowlands landrace of quinoa (Chenopodium quinoa Willd)

•Two landraces of quinoa from strongly contrasting habitats were investigated.•Most salt-induced changes in expression of 24 genes were common to both.•This short-term salt adaptation mechanism was mainly based on ABA-related responses.•Timing of gene expression changes reflected genotype-dependent strategies.•Similar variations in ABA and PA profiles were induced by salt in the two landraces.
