Transcriptomic response to nitrate addition. Selected significantly enriched GO terms within the N-addition trend set relative to all sequences on the array (A) using a modified Fisher's Exact Test in Blast2GO (FDR < 0.05). The plotted values are the average fold change for all probes in the enrichment group. Heat map of K. brevis trend set for N-addition (B) microarray studies. K-means clustering with a Euclidean distance metric were applied to a filtered data set requiring at least 1.7 fold change and a p-value ≤ 0.0001 in at least one time point for inclusion.
