Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

Transcriptionally inactive oocyte-type 5S RNA genes of Xenopus laevis are complexed with TFIIIA in vitro [PDF]
, 1987 An extract from whole oocytes of Xenopus laevis was shown to transcribe somatic-type 5S RNA genes approximately 100-fold more efficiently than oocyte-type 5S RNA genes.

Escaping Constraints to Innovate: Maternal Neofunctionalization in a HoxB4 Duplicate
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.Whole‐genome duplication in Xenopus laevis generated duplicated Hox genes that are largely constrained in sequence and developmental expression. However, HoxB4L uniquely acquired maternal expression through cis‐regulatory and protein structural divergence, illustrating how gene duplication enables transcription factors to escape pleiotropic constraints

A Genetic Mosaic Screen Reveals Ecdysone-Responsive Genes Regulating Drosophila Oogenesis
G3: Genes, Genomes, Genetics, 2016 Multiple aspects of Drosophila oogenesis, including germline stem cell activity, germ cell differentiation, and follicle survival, are regulated by the steroid hormone ecdysone.

Regulatory mechanisms of reproduction in locusts and grasshoppers
New Plant Protection, EarlyView.Regulatory networks composed of numerous coding and noncoding genes play crucial roles in the reproduction of locusts and grasshoppers. This review integrates mechanistic advances in reproductive regulation, highlighting environmentally adaptive pathways and providing prospective targets for eco‐friendly pesticides.

Spatiotemporal dynamics of early oogenesis in pigs
Genome BiologyBackground 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 ...

The 5' → 3' exoribonuclease XRN1/Pacman and its functions in cellular processes and development [PDF]
, 2012 XRN1 is a 5' → 3' processive exoribonuclease that degrades mRNAs after they have been decapped. It is highly conserved in all eukaryotes, including homologs in Drosophila melanogaster (Pacman), Caenorhabditis elegans (XRN1), and Saccharomyces cerevisiae (
