Genomic Evaluation of Recombination in Small Highly Inbred Beef Cattle Populations
The study characterizes recombination in small beef cattle populations, revealing higher rates in CGC composites compared to inbred Line 1 Herefords. It identifies significant SNP associations linked to recombination across various autosomes, highlighting complex polygenic influences, with implications for genetic diversity and breeding strategies ...

Meiosis-specific gene discovery in plants: RNA-Seq applied to isolated
Background Meiosis is a critical process in the reproduction and life cycle of flowering plants in which homologous chromosomes pair, synapse, recombine and segregate. Understanding meiosis will not only advance our knowledge of the mechanisms of genetic

The cohesin loader SCC2 contains a PHD finger that is required for meiosis in land plants.
Cohesin, a multisubunit protein complex, is required for holding sister chromatids together during mitosis and meiosis. The recruitment of cohesin by the sister chromatid cohesion 2/4 (SCC2/4) complex has been extensively studied in Saccharomyces ...

The PP2A‐B56 Binding Site LxxIxE Contributes to Asp‐Mediated Spindle Pole Stability
ABSTRACT The organization of microtubules into a mitotic spindle is critical for animal cell proliferation and involves the cooperation of hundreds of proteins whose molecular roles and regulation are not fully understood. The protein product of the Drosophila gene abnormal spindle, Asp, is a microtubule‐associated protein required for correct mitotic ...

From equator to pole: splitting chromosomes in mitosis and meiosis
During eukaryotic cell division, chromosomes must be precisely partitioned to daughter cells. This relies on a mechanism to move chromosomes in defined directions within the parental cell.

In Drosophila males, there is no synaptonemal complex and recombination does not occur. Thus, Drosophila male meiosis is a good model system for the analysis of achiasmate chromosome segregation. In addition, due to their large size, the meiotic spindles of Drosophila males are an excellent system for mutational dissection of the mechanisms of spindle ...

ABSTRACT Cells have an intrinsic ability to rapidly respond to environmental change to regulate cell cycle progression and membrane organisation, thereby affecting cell growth and division. The actin cytoskeleton is a highly dynamic complex of proteins that can rapidly reorganise to change the growth pattern of a cell.

Lanosterol 14 α-demethylase (CYP51) plays a crucial role in cholesterol biosynthesis. In gamete development, CYP51 is involved in initiating meiosis resumption in oocytes through its product, meiosis activating sterol (MAS).

Live imaging RNAi screen reveals genes essential for meiosis in mammalian oocytes
During fertilization, an egg and a sperm fuse to form a new embryo. Eggs develop from oocytes in a process called meiosis. Meiosis in human oocytes is highly error-prone, and defective eggs are the leading cause of pregnancy loss and several genetic ...

The NLS3 Motif in TPX2 Regulates Spindle Architecture in Xenopus Egg Extracts
ABSTRACT A bipolar spindle composed of microtubules and many associated proteins functions to segregate chromosomes during cell division in all eukaryotes, yet both spindle size and architecture vary dramatically across different species and cell types.
