PRESERVING GENOME FIDELITY. “Companion cell DNA does not contribute to the zygotic genome, and therefore reactivation of companion cell transposable elements does not risk the genome fidelity of the next generation. Together with its vital biological function to facilitate fertilization and promote postfertilization development with reduced dependence on water, the ability of the gametophyte to protect the integrity of the zygotic genome has probably contributed to the maintenance of this distinct “generation” during angiosperm evolution.”
