Discovery of POEM.

Caption

(A) An ovule inserted with a pollen tube that can fertilize. Ovule enlargement is observed upon fertilization. (B) An ovule without insertion of a pollen tube. Without insertion of a pollen tube, ovule enlargement is not observed. (C) An ovule inserted with a pollen tube that cannot fertilize. Even though fertilization has not occurred, ovule enlargement is observed due to release of PTCs into the ovule. Upon analyzing 100 ovules inserted with pollen tubes that cannot fertilize, the ovule size was on average, 2.5 times larger relative to ovules without insertion of a pollen tube.
