From: Acclimation with humic acids enhances maize and tomato tolerance to salinity
A Transcription maps of genes related to osmotic stress (drought/salinity) in root tissues of seedlings treated with humic acids (HA) in the first phase of the experiment acclimation period. B Specific salinity gene response up (blue) or down (red) regulated by HA treatment related to control. The gene descriptions are in Additional file 1: Table S2. The scale values are significant by t test and are expressed concerning control. Above the axis X, one can see the locus description in the maize root. The column label showed the gene SOS
