“Fusion” in fertilization: interdisciplinary collaboration among plant and animal scientists
- 341 Downloads
Fertilization is a unique biological process, where two highly specialized cells, gametes, fuse together to form a single cell that leads to a new generation of life. Although division is the inherent and essential feature of the cell, gametes have evolved to undergo the completely opposite process, fusion, during fertilization. Recent studies have revealed that fertilization and its related processes in plants and animals often share key molecules and/or mechanisms. Therefore, it has become more important to integrate our knowledge obtained from both plant and animal researches to better understand the gamete fusion that culminates in the regeneration of life.
After the generation of sperm and egg, a series of processes take place before fertilization completes. In general, sperm first makes its way to the egg of its own species with the help of chemical ques released from the egg or cells in its vicinity. Upon arrival of the sperm to the egg, the two cells adhere, recognize each...
