Arabidopsis AUGMIN8 Contains Two Independent Microtubule Association Domains

Cytoskeleton, EarlyView.
ABSTRACT Plant cells create a plasma membrane‐associated network of microtubules that are nucleated by γ‐tubulin ring complexes primarily through microtubule‐dependent microtubule nucleation (MDMN). This dynamic array organizes into specific patterns in response to developmental and environmental cues to influence primary cell wall construction.

The Influence of Drosophila Spire and Myosin V During Mid‐Oogenesis Is Independent of Their Direct Interaction

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 ...

Recent advances in understanding of meiosis initiation and the apomictic pathway in plants

Frontiers in Plant Science, 2014
Meiosis, a specialized cell division to produce haploid cells, marks the transition from a sporophytic to a gametophytic generation in the life cycle of plants.

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 ...

Implementation of meiosis prophase I programme requires a conserved retinoid-independent stabilizer of meiotic transcripts

Nature Communications, 2016
Meiosis is a cell division program that produces haploid gametes and is initiated by a retinoic acid-dependent process. Here the authors report that a meiosis-specific protein, MEIOC, is upregulated in a retinoic acid-independent manner and is required ...

Embryonic development of the Mediterranean starfish Hacelia attenuata

Developmental Dynamics, EarlyView.
Abstract Background Starfish play essential ecological roles as predators and ecosystem regulators; however, detailed developmental descriptions exist for only a handful of species, none of which are from the Mediterranean Sea. Results In this study, we provide the first full account of the development of the Mediterranean starfish Hacelia attenuata ...

Meiosis-specific cohesin component, Stag3 is essential for maintaining centromere chromatid cohesion, and required for DNA repair and synapsis between homologous chromosomes.

PLoS Genetics, 2014
Cohesins are important for chromosome structure and chromosome segregation during mitosis and meiosis. Cohesins are composed of two structural maintenance of chromosomes (SMC1-SMC3) proteins that form a V-shaped heterodimer structure, which is bridged by

Causal Association Between Lifestyle Behavior and Potential Risk Factors With Blepharoptosis

Eye &ENT Research, EarlyView.
ABSTRACT Background Blepharoptosis is among the most common disorders of eyelid malposition that may influence appearance and damage visual function, and both of these can have negative effects on the quality of life. Various types of blepharoptosis have been reported, including neurogenic, traumatic, congenital, mechanical, psychogenic, and myogenic ...

Protective Effects of Fenugreek and Stevia Extracts on Dexamethasone‐Induced Testicular Damage in a Rat Model

Food Safety and Health, EarlyView.
Fenugreek and stevia extracts protect against dexamethasone‐induced testicular damage in male rats by enhancing antioxidant defenses, improving sperm quality, and restoring hormonal balance, highlighting their potential as natural therapeutics for preventing corticosteroid‐induced reproductive toxicity.
