Abstract

Fertilization-dependent elimination of the persistent synergid cell is essential to block supernumerary pollen tubes and thus to avoid polyspermy in flowering plants. Little is known about the molecular mechanisms ensuring timely induction and execution of synergid cell death. We analyzed manually isolated maize synergid cells along their degeneration and show that they are gland cells expressing ...
