Although basal Angiosperms are phylogenetically distant from core Eudicots where the PLENA and the euAGAMOUS lineages occur, the behavior of the two Magnolia AGAMOUS genes during sarcotesta development is reminiscent of that of the two AGAMOUS lineages of core Eudicots. It would be interesting to ascertain whether and perhaps which of the two AGAMOUS genes found in both the basal Angiosperm M.grandiflora and some of the ANITA species gave rise to the two lineages now found in core Eudicots.
