Diversity and Evolutionary History of Iron Metabolism Genes in Diatoms
Fig 2
The three components of the reductive uptake system in diatoms.
Frequency of detected transcripts for ferric reductase (FRE), multi-copper oxidase (MCO) and iron(III) permease (FTR). Bars show proportion of strains within Bacillariophyceae (B), Fragilariophyceae (F), Mediophyceae (M) and Coscinodiscophyceae (C) where 1 or more transcripts were detected versus total strains.
