Forces shaping the Drosophila wing
How genes encode the three-dimensional shape of tissues is a fascinating problem in biology. Pioneering genetic studies in the fruit fly Drosophila have identified key genes that control the generation of force patterns in the developing wing. Shortrange force patterns generated by planar polarised myosins can promote boundary formation and tissue elongation during the larval wing disc stage. L...
متن کاملDrosophila egg chamber elongation
As tissues and organs are formed, they acquire a specific shape that plays an integral role in their ability to function properly. A relatively simple system that has been used to examine how tissues and organs are shaped is the formation of an elongated Drosophila egg. While it has been known for some time that Drosophila egg elongation requires interactions between a polarized intracellular b...
متن کاملThe submicroscopic structure of the Drosophila egg.
T H E wealth of mutants available in Drosophila provides unsurpassed opportunities for the study not only of the direct effects of genes on early embryological development but also of the complementary activities of the cytoplasm, which can be investigated in races in which 'female-sterile' genes have produced abnormal conditions in the egg. The most important pioneer in the study of gene effec...
متن کاملImaging Calcium in Drosophila at Egg Activation
Egg activation is a universal process that includes a series of events to allow the fertilized egg to complete meiosis and initiate embryonic development. One aspect of egg activation, conserved across all organisms examined, is a change in the intracellular concentration of calcium (Ca(2+)) often termed a 'Ca(2+) wave'. While the speed and number of oscillations of the Ca(2+) wave varies betwe...
متن کاملPhysical Mechanisms Shaping the Drosophila Dorsoventral Compartment Boundary
BACKGROUND Separating cells with distinct identities and fates by straight and sharp compartment boundaries is important for growth and pattern formation during animal development. The physical mechanisms shaping compartment boundaries, however, are not fully understood. RESULTS We combine theory and quantitative experiments to investigate the roles of different mechanisms to shape compartmen...
