Fertilization is the fusion of two haploid gametes, during the process of sexual reproduction, to initiate the development of a new diploid organism with mixed genetical heritage. In flowering plants, the pollen grain germinates once it reaches the carpel, and develops a tube that will reach and fuse with the ovule.

    Fusion of lipid bilayers to deliver genetic information is a process common to both viral infection and fertilization, and the two share common molecular mechanisms. Now, identification of fusion-facilitators shows that plants have their own unique slant on the fusion process.

    The stigma has a tightly regulated functional lifespan and is therefore a key determinant for floral receptivity. New evidence reveals how two transcription factors play a pivotal role in controlling stigma lifespan by regulating developmental programmed cell death in this tissue to terminate pollen receptivity.
