Profiling the GCS1-Based Gamete Fusion Mechanism

摘要: Angiosperm double fertilization is composed of two sets gamete fusion, in which sperm cells released from a pollen tube fuse with egg and central to produce an embryo endosperm, respectively. GCS1 was, for the first time, identified as membrane protein essential plant this indicates that regulated by molecular systems on surface. Interestingly, conserved various phylogenetically distant organisms, such algae, unicellular parasites, slime molds, some invertebrate species, Plasmodium Chlamydomonas orthologues have proved similarly function their fusion male factor. This finding ancient regulator; thus, elucidating GCS1-based mechanism should lead understanding eukaryotic system. Because novel transmembrane no well-known functional domains are present, mechanics remain elusive.
