Accepted: 19 March 2017/Published online: 10 April 2017© The Botanical Society of Japan and Springer Japan 2017 of their diversity and conservation among organisms as diverse as plants and animals is still limited. In 2006, a membrane protein called GENERATIVE CELL SPECIFIC 1 (GCS1) was identified as a male factor essential for gamete fusion in plant Arabidopsis thaliana (Mori et al. 2006). Later, an orthologue of GCS1 was found also in malaria parasite, Plasmodium berghei, and shown to have the same function in gamete fusion as A. thaliana GCS1 (Hirai et al. 2008). This was the first demonstration that the same factor is required for the same step of fertilization in both plants and animals. In another case, a molecular framework that regulates self-incompatibility was found to be very similar between primitive chordate Ciona intestinalis and flowering plants, although they utilize different molecules (Harada et al. 2008). These landmark studies give us a compelling reason to examine and compare both plants and animals to better understand the principle of fertilization, which should also reveal the diversity and conservation among them. In this special issue of JPR Symposium “Fusion in Fertilization: Interdisciplinary Collaboration among Plant and Animal Scientists”, related yet diverse aspects of fertilization, from sex determination to nuclear fusion and from plants to animals, were reviewed and discussed. Sex determination is the first step of sexual reproduction and leads to sexual differentiation of gametes. Although almost all eukaryotic species exploit sexual reproduction, sex determination mechanism evolves rapidly and appears highly diverse among species (Bachtrog et al. 2014), and the molecular basis of sex determination remains unknown in many species. Sekimoto (2017) focused on the sexual reproduction in charophycean unicellular alga, Closterium peracerosum-strigosum-littorale complex, along with another model volvocine alga, Chlamydomonas reinhardtii, covering not only sex determination mechanism but also
