Change in Gene Expression in Plant Roots Inoculated with Rhizobia and in Response to Nitrogen Treatment Shows that Regulation of Nitrogen Mobilization Genes Varies upon Nodulation Status.

(A and C) Heatmap and number of genes in each cluster for genes clustered over “raw” log₂ values (A) and log₂ fold N responses (C). Cluster sizes and membership is specified and also depicted by the colored triangles.

(B) Overview of main effect in clusters 2, 5, and 11, with representative genes (as referred to in text) and examples of the expression levels of representative genes. For each gene the cluster in the “response” data (C) is given in parentheses. n = 3 except for Rhizobia-6hNitrogen where n = 2.
