Neofunctionalisation of basic helix−loop−helix proteins occurred when embryophytes colonised the land

What is it about?

RSL proteins control the development of structures that develop from single cells at the surface of embryophytes (land plants). We show that RSL proteins exist in streptophyte algae but are functionally different from those of land plants suggesting that RSL proteins acquired new functions in the lineage leading to the embryophytes around the time they colonised the land.
