Fig. 3
Protein expression patterns in Phaeocystis antarctica photosystems. Expression patterns are shown under changing metal availability, with Phaeocystis grown at an irradiance level of 25 μmol photons/m2/s. Mean standard (Z) scores shown for each detected protein involved in photosynthesis under replete, low iron (Fe), low manganese (Mn), and combined low Mn and low Fe conditions. These are displayed within a schematic representation of the photosystem shown with the number of metal ions per macromolecule9,10. Treatments significantly different to replete treatments are indicated with black asterisks; proteins differentially expressed between the low Fe vs. the low Mn and low Fe treatment are noted with a gray star. PsaA was detected and quantified using modified search and quantification procedures as described in Methods. Full protein names and source data are shown in the Source Data File. Significant differences were determined using empirical Bayes quasi-likelihood F test (with edgeR), where n = 3 biologically independent samples per treatment
