A horizontally acquired pantothenate gene drives vitellogenin's benefit to whitefly symbiosis persistence

open access: yesInsect Science, EarlyView.
This diagram illustrates that the horizontally transferred panBC influences the level and localization of vitellogenin (Vg) by facilitating pantothenate production and juvenile hormone (JH) biosynthesis. In turn, Vg shields symbionts by suppressing autophagic degradation in bacteriocytes.

Spatiotemporal dynamics of early oogenesis in pigs

open access: yesGenome Biology
Background In humans and other mammals, the process of oogenesis initiates asynchronously in specific ovarian regions, leading to the localization of dormant and growing follicles in the cortex and medulla, respectively; however, the current ...

Myosin VI is expressed in developing ovarian follicles in Drosophila but is not essential for effective oogenesis

open access: yesFrontiers in Cell and Developmental Biology
Myosin VI is the only actin-based motor known to move toward the minus end of actin filaments. This protein is involved in many different cellular processes, such as endocytosis, autophagy, secretion, and regulation of actin organization and dynamics ...

Sox9 and Vasa Gene Expression During Gonadal Differentiation in Larvae of the Urodele Amphibian Ambystoma mexicanum

open access: yesActa Zoologica, EarlyView.
ABSTRACT The study of genes involved in sexual differentiation, as Vasa and Sox9, is of great importance, as they serve as specific markers for the germline and the male differentiation pathway, respectively. This study characterized using immunofluorescence the expression of the Vasa and Sox9 genes and laminin during gonadal differentiation in larvae ...

No Female Germline Stem Cells Were Identified by Advanced Dual Recombinase‐Based Lineage Tracing System

open access: yesCell Proliferation, EarlyView.
Schematic summary of the dual‐recombinase lineage tracing strategies to determine whether female germline stem cells (fGSCs) exist and sustain the ovarian follicle pool in adult female mice. Our study concluded that no fGSCs exist and contribute to oocyte regeneration in adult female mice with different tracing systems. ABSTRACT Whether female germline

Oogenesis Karang Sclerectinia Caulastrea furcata dan Lobophyllia corymbosa

open access: yesHayati Journal of Biosciences, 2007
Caulastrea furcata and Lobophyllia corymbosa are corals of order Sclerectinian. Caulastrea furcata is the only species of genus Caulastrea that could be found in Kepulauan Seribu and L. corymbosa is a rare species.

Phosphorylation of BigH1 regulates its expression pattern and promotes embryonic development

open access: yesThe FEBS Journal, EarlyView.
Phosphorylation is a key regulator of the linker histone variant BigH1 during Drosophila embryogenesis. We reveal that N‐terminal phosphorylation promotes the timely removal of BigH1 from chromatin. In contrast, C‐terminal phosphorylation supports early nuclear divisions and embryonic viability.

Analysis of drongo, a new Drosophila zinc finger gene expressed during oogenesis and neurogenesis [PDF]

open access: yes
This thesis is an investigation into the function of the drongo, a novel gene with a zinc finger motif, orignally isolated via enhancer trapping from its expresssion in the embryonic neuroectoderm.

Peptides in insect oogenesis

open access: yes, 2019
© 2018 Elsevier Inc. The physiological control of reproduction in insects depends on a combination of environmental and internal cues. In the adult stage, insects become sexually mature and generate gametes.

Errors in chromosome segregation during oogenesis and early embryogenesis [PDF]

open access: yes, 2010
Errors in chromosome segregation occurring during human oogenesis and early embryogenesis are very common. Meiotic chromosome development during oogenesis is subdivided into three distinct phases.
