The function of bindin in fertilization.

Introduction:

Bindin is a protein that presents in the acrosome of the sperm of many aquatic animals, for example, sea urchin. This protein has a role in species-specific sperm-egg recognition. Moreover, bindin plays a central role in fertilization process.

Expert Solution & Answer

Explanation of Solution

In the case of aquatic animals, fertilization (fusion of egg and sperm) is external that is fertilization takes place in open sea water, not inside the body. Problem with this type of fertilization is sperm and egg of many aquatic animals are exposed in the same seawater. So cross-fertilization may occur.

In order to produce a viable embryo, the sperm of one species must recognize egg of its own species. In 1970, Victor Vacquier isolated a 30,500-Da protein from the Strongylocentrotus purpuratus acrosome and found it to be able of binding to the eggs belonging to same species. He also found out Bindin isolated from other sea urchin species are indeed different. This protein prevents cross-fertilization and is species specific.

The vitelline envelope of the egg has a specific receptor or binding site for acrosomal bindin. These receptors can differentiate between bindin of two closely related species (same genus). so, the sperm of one specific species can only bind to the egg of same species. This way aquatic animals like sea urchin prevent cross-fertilization and help in species-specific egg and sperm recognition and fusion.

Conclusion

Therefore, it can be concluded that the cross-fertilization is the big problem in the case of animals that practice external fertilization. To prevent this a species-specific protein called bindin present in the acrosome of the sperm and its specific receptors are present in the egg of the same species. This way sperm of one species can only fertilize the egg on its own species.

For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible. Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating.
