Gene expression profiling of S. microadriaticum. a Principal component analysis of transcriptomic profiles of algal cells living in hospite (Spis) and ex hospite (Con, Fe, N, P). b Principal component analysis of transcriptomic profiles of algal cells living in different culturing conditions: Control, iron (Fe), nitrogen (N), and phosphate limitation (P). c Spearman correlation of expression changes between iron-limited and in hospite S. microadriaticum, in comparison with control cells. Each dot represents a differentially expressed gene identified from both conditions in comparison with ex hospite control. The correlation coefficient and p-value were calculated based on their log-transformed fold changes. Colors represent the dot density which corresponds to increasing density from gray, blue, and red to yellow. d Spearman correlation of expression changes between phosphate-limited and in hospite S. microadriaticum, in comparison with control cells. e Spearman correlation of expression changes between nitrogen-limited and in hospite S. microadriaticum, in comparison with control cells. f Expression changes of co-directionally changed genes in Spis/Con and N/Con. The genes on the x-axis were ranked by log-transformed fold changes in N/Con comparison. Colors represent the two comparisons as indicated: dark orange is for N/Con, while light orange is for Spis/Con
