a Schematic representation of N transport and assimilation in P. calceolata based on the gene content. The color code indicates if the number of gene copies for a specific function is overrepresented (green), equally represented (blue), underrepresented (orange) or absent (red) in P. calceolata genome compared to the mean of eight pico-nano photosynthetic eukaryotes. Gene copy number for each function is indicated in Supplementary Data 9. b Domain organization of NIT-sensing proteins in P. calceolata. Orange boxes are NIT-sensing domains (IPR13587), blue boxes are serine–threonine/tyrosine-kinase domain (IPR20635), and yellow rectangles are transmembrane domains. c Relative expression levels (TPM) of three NIT-sensing genes in low-nitrate (<2 µM) and high-nitrate (>2 µM) environments. P values of Mann–Withney–Wilcoxon tests between low- and high-nitrate samples are indicated for each gene. Significant P values (<0.01) are in bold.
