Sea urchin bindin divergence predicts gamete compatibility.
Studies on the evolution of reproductive proteins have shown that they tend to evolve more rapidly than other proteins, frequently under positive selection. Progress on understanding the implications of these patterns is possible for marine invertebrates, where molecular evolution can be linked to gamete compatibility. In this study, we surveyed data from the literature from five genera of sea ...
متن کاملThe evolution of sea urchin sperm bindin.
Sea urchins have been model organisms for the study of fertilization for more than a century. Fertilization in sea urchins happens externally, which facilitates the study of sperm-egg attachment and fusion, and means that all of the molecules involved in gamete recognition and fusion are associated with the gametes. Sea urchin sperm bindin was the first "gamete recognition protein" to be isolat...
متن کاملEvolution of bindin in the pantropical sea urchin Tripneustes: comparisons to bindin of other genera.
Bindin, a sea urchin sperm protein, mediates sperm-egg attachment and membrane fusion and is thus important in species recognition and speciation. Patterns of bindin variation differed among three genera that had been studied previously. In two genera of the superorder Camarodonta, Echinometra and Strongylocentrotus, both of which contain sympatric species, bindin is highly variable within and ...
متن کاملSelection and demographic history shape the molecular evolution of the gamete compatibility protein bindin in Pisaster sea stars
Reproductive compatibility proteins have been shown to evolve rapidly under positive selection leading to reproductive isolation, despite the potential homogenizing effects of gene flow. This process has been implicated in both primary divergence among conspecific populations and reinforcement during secondary contact; however, these two selective regimes can be difficult to discriminate from e...
متن کاملSimultaneous positive and negative frequency-dependent selection on sperm bindin, a gamete recognition protein in the sea urchin Strongylocentrotus purpuratus.
Gamete-recognition proteins often, but not always, evolve rapidly. We explored how variation in sperm bindin influences reproductive success of the sea urchin Strongylocentrotus purpuratus during group spawning in the sea. Despite large variation in male and female abundance and neighbor distances, males with common genotypes had higher reproductive success than males with rare genotypes. Howev...
