Role of Bicaudal-D in patterning the Drosophila egg chamber in mid-oogenesis [PDF]

open access: yes, 1996
Skip to Next Section The Bicaudal-D (Bic-D) gene is required early in Drosophila oogenesis for the differentiation of an oocyte from one of a cluster of 16 interconnected germarial cells.

Genes expressed during oogenesis in Calliphora erythrocephala and Drosophila melanogaster

open access: yes, 1990
We were interested in identifying genes in the dipteran flies Calliphora erythrocephala and Drosophila melanogaster with a role in oogenesis and early embryogenesis. A biochemical screen was used to complement the extensive genetic screens that have been

Characterizing the role of the Early Gene at 23 (E23) in Drosophila Melanogaster Oogenesis [PDF]

open access: yes, 2016
Extracted text; Drosophila melanogaster (fruit fly) females undergo oogenesis to create oocytes from undifferentiated stem cells in the ovary. Similar to estrogen in humans, the steroid hormone ecdysone in fruit flies has a known role in facilitating ...

Transcriptomic analysis of the spatiotemporal axis of oogenesis and fertilization in C. elegans

open access: yesFrontiers in Cell and Developmental Biology
Caenorhabditis elegans hermaphrodite presents a unique model to study the formation of oocytes. However, the size of the model animal and difficulties in retrieval of specific stages of the germline have obviated closer systematic studies of this process

Stage-specific regulation of programmed cell death during oogenesis of the medfly Ceratitis capitata (Diptera, Tephritidae)

open access: yes, 2007
In the present study, we describe novel features of programmed cell death in developing egg chambers occurring during mid- and late-oogenesis of the medfly Ceratitis capitata.

Molecular genetics of oogenesis in Drosophila melanogaster

open access: yesInvertebrate Survival Journal, 2004
Gonadal development requires complex differentiation programs leading to the production of functional female and male gametes. Upon fertilization, while the male germ cell contributes to the newly formed zygote only its genetic material, the female germ ...

Mitochondria during sea urchin oogenesis

open access: yes, 2017
Sea urchin represents an ideal model for studies on fertilization and early development, but the achievement of egg competence and mitochondrial behaviour during oogenesis remain to be enlightened.
