A paper by Cell Biology and Molecular Genetics' José Feijó suggests that a family of signal receptors used by human neurons is also essential for reproduction in the moss Physcomitrella patens.
At left, a wild-type (normal) P. patens sperm cell (red circle) swims toward—and eventually enters—the archegonia, which contains the moss' eggs. On the right, a mutant sperm cell without the receptors (green circle) swims but does not approach the archegonia.
