Like all other eukaryotes, metal ions are essential nutrients for algae, which must be assimilated from the environment. At the same time, in excess, metal ions are inherently toxic. Reflecting the complex evolutionary relationships among the alga groups, algal genomes encode a variety of widely conserved and unique transport proteins to handle the balance between nutrient and toxin. Each genomic repertoire enables algal species to thrive in environments with unique biogeochemical characteristics compared to non-algal species commonly used as reference organisms for metal homeostasis. As a result, the study of algal metal homeostasis broadens our understanding of how phenotypically and taxonomically divergent eukaryotes have evolved to perform photosynthesis in disparate environments. These niches are as varied as marine versus freshwater, aquatic versus deserts, polar versus tropical, and free-living versus endosymbiotic. While access to genome sequences and predicted gene models is increasing, enabling identification of characterized proteins through computational genomics analyses, the next stage is developing transformation approaches and RNA-guided endonuclease systems for understanding the molecular and biological function of metal-regulated genes unique to algae.
