Fig. 2: Global distribution of different nitrogen assimilation-related genes in the Tara Ocean metagenomic samples.

The pie map shows the four major nitrogen uptake genes categories (Supplementary Table 1) from the surface (SF) (A) and deep chlorophyll maximum (DCM) (C) samples, where different colors represent specific gene categories, blue for amino acids transporters (n = 13), yellow for the ammonium transporters (n = 1), red for the nitrate assimilation-related genes (n = 4) and green for small organic molecule transporters (n = 2). The extended bar plots compare the proportions (%) of these gene categories between polar and non-polar regions for SF (B) and DCM (D) samples, with the blue and yellow bars indicate the polar and non-polar samples, respectively.
