ABC transporters clades were present in the last common ancestor of the Archaeplastida.

Cladogram of Archaeplastida showing ABC transporter clade origins and losses during plant evolution. Blue circles represent first appearances of a clade, black circles represent the loss of a clade in a particular lineage. Also shown are the relative distributions of ABC transporters into their respective clades for each species included in our analysis, where each distinct coloured block represents a separate ABC transporter protein clade.
