vsiRNA profiling during R. prolixus oogenesis.

open access: yes, 2021
(A) Length distribution of the RpVs small RNAs in previtellogenic stages (PVS) of oogenesis. (B) Length distribution of the viral small RNAs in mature eggs (Egg). In both stages of R.

Germ cell cluster formation and ovariole structure in Puto albicans and Crypticerya morrilli (Hemiptera: Coccinea). Phylogenetic implications

open access: yesEuropean Journal of Entomology, 2010
The organization and development of ovaries in representatives of two families (Putoidae and Monophlebidae) of scale insects are described. Developing ovaries of Puto albicans McKenzie, 1967 and Crypticerya morrilli (Cockerell, 1914) consist of numerous ...

Mechanisms of programmed cell death during oogenesis in Drosophila virilis

open access: yes, 2007
We describe the features of programmed cell death occurring in the egg chambers of Drosophila virilis during mid-oogenesis and late oogenesis. During mid-oogenesis, the spontaneously degenerating egg chambers exhibit typical characteristics of apoptotic ...

Novel roles for ecdysone receptor in the Drosophila germline

open access: yes, 2023
Oogenesis, the process by which a viable egg is produced, demands carefully coordinated communication between somatic and germ cell populations, relying on both local and systemic factors such as steroid hormones for signaling. In Drosophila, the steroid

Nutrient-dependent regulation of a stable intron modulates germline mitochondrial quality control

open access: yesNature Communications
Mitochondria are inherited exclusively from the mothers and are required for the proper development of embryos. Hence, germline mitochondrial quality is highly regulated during oogenesis to ensure oocyte viability.

oogenesis

open access: yes, 1996
Notch (N) and other neurogenic genes have been implicated in two fundamental processes, lateral specification of cell fates, and epithelial development. Previous studies have suggested that the neurogenic gene brainiac (brn) is specifically required for ...

The function of nonmuscle myosins during oogenesis in Caenorhabditis elegans [PDF]

open access: yes, 2013
Oogenesis in C. elegans requires the activity of type II nonmuscle myosins, complexes containing two heavy and four light chains that bind and move actin.

Schematic of NC chromatin states during Drosophila oogenesis.

open access: yes, 2013
(A) Early oogenesis (up to stage 1) marks the formation and budding of the egg chamber from the germarium. The 16-cell syncytium arises from 4 mitotic divisions with incomplete cytokinesis; one cell becomes an oocyte which arrests during meiotic prophase

Изменение актинового цитоскелета и кольцевых каналов питающих клеток Calliphora erythrocephala в оогенезе

open access: yesФактори експериментальної еволюції організмів, 2014
Aims. The purpose of this study was to investigate changes of the actin cytoskeleton syncytial clusters in ovaries C. erythrocephala at different stages of oogenesis. Methods. Ovarioles were stained phalloidin- FITC and DAPI.
