Attractive ovules

Curr Biol. 1997 Feb 1;7(2):R64-6. doi: 10.1016/s0960-9822(06)00037-6.


The guidance of a pollen tube through the female flower to reach an ovule is genetically controlled and occurs only if the ovule's embryo sac has developed, suggesting that the embryo sac is the source of a specific pollen tube attractant.
