Fig. 6From: Genome-wide analysis of the basic leucine zipper (bZIP) transcription factor gene family in six legume genomesExpression profiles of legume bZIP genes. a–d Clustering of legume bZIP genes according to their expression profiles in tissues including nodules, roots, stems, flowers, and pods and seeds at different developmental stages in Gm (a), Pv (b), Mt (c) and Lj (d). The color scale represents log10 of the average signal values. e, f The up- and down- regulated bZIP genes identified in drought-stressed roots and shoots (e) and salt-stressed roots (f). The color scale represents the fold change in the gene expression value compared with the controlBack to article page
