Transcriptional response of C. reinhardtii to N starvation and lipid accumulation. a Heatmap representation for the hierarchical clustering of the log2 expression changes in 2,147 post-filtered set of transcripts. Red (blue) indicates a relative increase (decrease) of expression. Color intensities are proportional to fold change magnitude. b Default view of the front page of the Chlamy Network Portal. In the portal, 2,147 transcripts are organized into 215 modules, 118 regulatory influences and 411 motifs. The site includes a powerful Apache Solr-based faceted search and navigation tools. The portal content is also linked to other information resources like Phytozome, STRING, GO categories and relevant literature. c, d Differentially expressed transcripts organized as a sequential set of transcriptional waves: 17 monotonic transcriptional waves composed of 125 transcriptional modules and 1,482 transcripts (c), and 15 transient transcriptional waves of 55 transcriptional modules and 758 transcripts (d). Each line represents average fold change for a given transcriptional wave. The timestamp on each wave reflects the timepoint at which transcript level change crosses a twofold threshold
