Arabidopsis thaliana accessions have extensive natural variation in environmental adaptation and Shahdara (Sha) in particular differs substantially from other accessions such as Landsberg erecta (L er ). Metabolite analysis, RNA sequencing and physiological experiments found striking differences in amino acid profile and gene expression between L er and Sha at low water potential. The data show the differing metabolic response to low water potential of the two accessions and the possible influence of both biotic and abiotic factors in shaping the specific adaptation of Sha.
