Proposed model of PI3K signaling network in algae under N starvation based on relative gene expression in T411 and its unique physiology. Changes in the relative mRNA levels of genes identified in the PI3K signaling pathway in T411 under −N conditions compared to wild-type cells grown in the same conditions. Genes and pathways denoted in blue are downregulated and those in red are upregulated in T411. In case of pathways, colors denote the response of the majority of genes. For detailed gene annotation, please refer to Supplemental Table S5.
