Marine Ecology, EarlyView.ABSTRACT The soldier crab, Mictyris guinotae, is a dominant intertidal crustacean associated with sand flats in the vicinity of the Urauchi River estuary on Iriomote Island, Japan. We compared various aspects of its reproductive biology at two sites (the river mouth and upper reach) on exposed bare sand flats 300 m and 3000 m upstream from the mouth ...

Molecular control of oogenesis
Biochimica et Biophysica Acta (BBA) - Molecular Basis of Disease, 2012 Oogenesis is a complex process regulated by a vast number of intra- and extra-ovarian factors. Oogonia, which originate from primordial germ cells, proliferate by mitosis and form primary oocytes that arrest at the prophase stage of the first meiotic division until they are fully-grown.

Pre‐oviposition development of the brown anole (Anolis sagrei)
Developmental Dynamics, Volume 255, Issue 2, Page 145-167, February 2026.Abstract Background The brown anole, Anolis sagrei, has emerged as a representative squamate species for developmental studies during the past decades. Novel functional tools have been established to manipulate embryogenesis through genome editing or the introduction of small molecule inhibitors, and their effective use requires a thorough ...

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

Geographic Divergence and the Genomic Basis of Reproductive Diapause in Drosophila triauraria
Molecular Ecology, Volume 35, Issue 3, February 2026.ABSTRACT Adjusting reproduction timing to environmental cues is essential for lifetime fitness. In many insects, reproductive diapause shows clinal variation along environmental gradients such as photoperiod and temperature. How such continuous trait variation may be encoded at the molecular level and maintained in the presence of gene flow remains ...

hnRNPU Safeguards Oocyte Development and Female Fertility via Regulation of Alternative Splicing
The FASEB Journal, Volume 40, Issue 2, 31 January 2026.Heterogeneous nuclear ribonucleoprotein U (hnRNPU) is essential for oocyte development and female fertility. Oocyte‐specific deletion of Hnrnpu leads to follicular arrest, impaired meiotic maturation, mitochondrial dysfunction, and infertility.
