From: Acclimation with humic acids enhances maize and tomato tolerance to salinity
Relative expression of genes quantified by RT-qPCR in maize roots. The maize seedlings were treated or not (control) with 4.0 mM C L−1 humic acids (HA) or 60 mM NaCl. T. A Basic leucine zipper (ZmbZIP17), B Protein highly conserved N-terminal (ZmNAC66), C SNF1-related protein kinase 1 (ZmSnRK1), D Protein serine/threonine kinase (ZmSnRK2.2). The means (n = 4) were followed by the standard deviation
