Book Description
This book will give an overview of insect ovaries, showing the diversities and the common traits in egg growth processes. The idea to write this book developed while looking at the flood of information which appeared in the early 1980s on early pattern formation in Drosophila embryos. At this time a significant breakthrough was made in studies of this little fly, combining molecular biological methods with classical and molecular genetics. The answers to questions about early pattern formation raised new questions about the architecture of ovaries and the growth of eggs within these ovaries. However, by concentrating only on Drosophila it is not possible to form an adequate picture of what is going on in insect ovaries, since the enormous diversity found among insects is not considered sufficiently. Almost forgotten, but the first to study the architecture of ovaries, was Alexander Brandt writing in 1878 in aber das Ei und seine Bildungsstaette (On the egg and its organ of development). More than 100 years later, a series of ten books or more would be required to survey all the serious informa tion we have today on insect oogenesis. Thus, this book is a personal selection and personal view on the theme, and the authors must be excused by all those scientists whose papers could not be included. The book briefly describes the ectodemes, i. e.

Book Description
This volume provides current up-to-date protocols for preparing the ovary for various imaging techniques, genetic protocols for generating mutant clones, mosaic analysis and assessing cell death. Chapters address methods for performing genome wide gene expression analysis and bioinformatics for studies of RNA-protein interactions. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and cutting-edge, Drosophila Oogenesis: Methods and Protocols aims to ensure successful results in the further study of this vital field.

Book Description
In this comprehensive and cutting-edge book, leading experts explore the parameters that define germline stem cells and the mechanisms that regulate the cell behavior in order to better isolate, characterize and maintain them. The volume begins by providing protocols for germline stem cell identification and regulation in model organisms, and concludes with detailed chapters covering current techniques involving in vitro culture and the applications of the cells.

Book Description
How the size of an organ is established and altered during evolution is poorly understood. The ovary of fruit flies of the genus Drosophila serves as an interesting model for understanding organ size evolution, as the number of egg-producing structures called ovarioles determines the ovary's functional 'size'. Species with more ovarioles can lay more eggs, and ovariole number can evolve rapidly between closely related species. However, the developmental and genetic mechanisms that determine and alter ovariole number were poorly characterized at the beginning of this thesis. I first analyzed the developmental basis of plasticity and species-specific ovariole number changes in D. melanogaster and closely related species. This analysis revealed distinct developmental mechanisms that alter ovariole number via changes in one cell type (terminal filament cells) in the developing ovary. To characterize the genetic mechanisms underlying proliferation patterns and potential cell-type interactions within the ovary, I then studied the role of the Hippo pathway in the somatic and germ cells of D. melanogaster. I uncovered a complex interaction between somatic cells and germ line cells, where proportional growth of these cell types is maintained by the Hippo pathway via interactions with the EGFR and JAK/STAT pathways. Finally, I expanded this work to investigate the physical, ecological, and developmental parameters that influence ovariole number evolution in Hawaiian Drosophila, where previous studies suggested that ovariole number correlated with larval food substrate. I describe my ongoing efforts to test correlations of ecology and ovariole number in a phylogenetic context in Hawaiian Drosophila. Primary differences in ovariole number between species occur through changes in cell number.
