Figure 1

(a) Transmission electron microscopy image of a P. purpureum cell showing the central pyrenoid (Py), cell membrane (CM), starch granules (S) and plastid thylakoids (Th). (b) Percentage of single protein RAxML trees (raw numbers shown in the bars) that support the monophyly of P. purpureum (bootstrap ≥90%) solely with other Plantae members (exclusive), or in combination with non-Plantae taxa that interrupt this clade (non-exclusive). These latter groups of trees are primarily explained by red/green algal EGT into the nuclear genome of chromalveolates. For each of these algal lineages, the set of trees with different numbers of taxa (x) ≥4, ≥10, ≥20, ≥30 and ≥40 in a tree are shown. Each tree has ≥3 phyla. The Plantae-only groups are reds-greens-glaucophytes (RGGl) and reds-greens (RG).
