Figure 2

Cluster analysis of a positive ion model (A) and a negative ion model (B) in DN and DS. Red indicates a high expression of metabolites and blue indicates a low expression of metabolites. Columns represent all samples and rows represent all metabolites. DN is DXWR without salt treatment and DS is DXWR under salinity.
