Identification of NO3- response and hormonal cross-talk modules. (a) For each pair of gene lists (NO3- responsive (this work) or hormone responsive [29]), a P-value (randomization test; see Materials and methods) was computed and is shown in the table below the blue diagonal. Entries in the blue diagonal give the gene list size in number of genes. Above the diagonal the size of the intersection of each pair of studied gene lists is given. Note that P-value = 0 means P-value < 0.001. Analysis of the P-values included within the yellow outline led to the building of gene modules depicted in the conceptual model provided in (b). ABA, absisic acid; ACC, 1-aminocyclopropane-1-carboxylic-acid (ethylene precursor); BL, brassinolides; CK, cytokinins; GA, gibberellic acid; IAA, indole acetic acid (auxin); MJ, methyl jasmonate.
