Plastid Gene Loss and Compensatory Mechanisms or Adaptations in Eustigmatophytes

Note.—The table lists all conserved plastid genes inferred to have been lost at any point of the eustigmatophyte phylogeny (including the stem branch). Presence/absence of the genes in individual taxa is indicated by blue and white squares, respectively (for simplicity, related species or strains with the same gene occurrence pattern were grouped into broader taxa). The Greek letter Ψ indicates that the psb28 gene in Vischeria sp. CAUP Q 202 is likely a pseudogene. For each gene, a mechanism or adaptation that seems to compensate for the respective gene loss in the taxa concerned is indicated; if none is apparent, putative functional consequences of the gene loss are specified.
