Researchers use optogenetics to activate and inactivate signaling pathways – News-Medical.net
Proper embryonic development of the fruit fly Drosophila melanogaster is governed by patterns of protein activity bequeathed to the fertilized egg by its mother.
Proper embryonic development of the fruit fly Drosophila melanogaster is governed by patterns of protein activity bequeathed to the fertilized egg by its mother. While the embryo is still a single cell, the maternal cells surrounding it deposit certain proteins inside it at specific locations.
This establishes protein gradients that direct the development of embryonic features along its anterior-posterior and ventral-dorsal axes. Later, the embryo receives another round of maternal information,…
