From: Host origin of plastid solute transporters in the first photosynthetic eukaryotes
Plastid targeted solute transporters of putative 'Cyanobacterial' (that is, plastid endosymbiont) origin in Plantae. For details of tree building see Figure 2. The filled magenta circle shows the node that unites the Plantae taxa as sister to cyanobacteria. The different photosynthetic groups are shown in different text colors: blue for cyanobacteria, red for red algae, green for green algae and land plants, and brown for chromalveolates. The inclusion of chromalveolates or Euglenozoa (Eugl.) within the Plantae is believed to reflect horizontal or endosymbiotic gene transfer events (for example, [50]). The two transporters are: (a) TGD1, trigalactosyldiacylglycerol 1, lipid transporter; and (b) ABC1-family transporter protein. The name of the A. thaliana solute transporter used for the query is indicated for both trees shown in this figure.
