Assignment of upregulated transcripts to bacterial lineages under dehydrated (a) and hydrated (b) conditions. Bacterial transcripts were separately assessed for upregulation under the two distinctive hydration stages of the lichen host. The two datasets were used to assign corresponding taxa to the filtered transcripts. The output of the analysis was visualized with Krona charts [51]. Segment coloration was adapted to distinguish between higher taxonomic ranks: Proteobacteria (blue), Actinobacteria, Firmicutes, Cyanobacteria (red), Bacteroidetes (green-yellow)
