Meiotic behavior and karyotypic variation in Acledra (Pentatomidae, Heteroptera)
Genetics and Molecular Research, 2010 Acledra comprises 15 taxonomically identified species, most of which are crop pests. This is the first cytogenetic study of species of this genus. Acledra kinbergii and A. modesta showed the modal number of the Pentatomidae (2n = 14 = 12 + XY), while A.

Animal Research and One Health, EarlyView.This study delineates the early sex differentiation timeline in the northern snakehead (Channa argus). These findings provide a foundation for future sex‐control breeding in this economically important species. ABSTRACT The northern snakehead (Channa argus) is an economically important aquaculture species in China.

Meiotic chromosome behavior in spread preparations of yeast. [PDF]
The Journal of cell biology, 1988 Chromosome behavior in meiosis is well characterized from cytological and genetic descriptions but little is known of the underlying molecular mechanisms, largely because no one experimental system has been developed to support an integrated application of modern cytological, genetic, and molecular biological methods.

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope
Animal Research and One Health, EarlyView.FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable

Crop Breeding and Applied Biotechnology, 2008 Chromosome numbers and meiotic behavior are presented for the first time for Hypericum caprifoliatum (2n=48), H. cf carinatum (2n=48) and H. polyanthemum (2n= 32) and confirmed the H. perforatum (2n=32) number. Chromosomes are very small (ca. 1 to 2 mm).

Oocyte–cumulus cell interaction: a key factor in early embryo development
Biological Reviews, EarlyView.ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.

Cytoskeleton, EarlyView.ABSTRACT Cooperativity between cytoskeletal proteins is crucial for spatiotemporal coordination in biological processes, like oogenesis. In mammalian and Drosophila oogenesis, proper assembly and function of actin networks require coordination between actin assembly factors Spire and formins, as well as actin‐associated proteins like myosins and Rab ...

Oogenesis and germinal bed morphology of the brown anole (A. sagrei)
Developmental Dynamics, EarlyView.Abstract Background The brown anole is a model species of the genus Anolis, a squamate (encompassing lizards and snakes) group widely studied in evolutionary, behavioral, and developmental biology. Full genome annotation, the establishment of gene editing techniques, and comprehensive description of reproductive tract morphology and embryogenesis in ...
