Figure 2

Clusters of nitrate assimilation genes in microalgae. NIA1 and NII1 (genes encoding NR and NiR) are the only genes conserved in all clusters represented. All clusters have been arranged to show NIA1 gene fixed in the middle of the figure. All the genes represented are involved in nitrate assimilation and molybdenum metabolism with exception of Cytb5R whose relationship with nitrate metabolism is unknown. *In Micromonas RCC299 NIA1 and NAR1 are overlapped.
