Chromosomal rearrangements in cattle and pigs revealed by chromosome microdissection and chromosome painting [PDF]
A pericentric inversion of chromosome 4 in a boar, as well as a case of (2q-;5p+) translocation mosaicism in a bull were analysed by chromosome painting using probes generated by conventional microdissection. For the porcine inversion, probes specific for p arms and q arms were produced and hybridised simultaneously on metaphases of a heterozygote ...

A strategy for the characterization of minute chromosome rearrangements using multiple color fluorescence in situ hybridization with chromosome-specific DNA libraries and YAC clones [PDF]
The identification of marker chromosomes in clinical and tumor cytogenetics by chromosome banding analysis can create problems. In this study, we present a strategy to define minute chromosomal rearrangements by multicolor fluorescence in situ ...

Dynamic epigenetic states of maize centromeres
The centromere is a specialized chromosomal region identified as the major constriction, upon which the kinetochore complex is formed, ensuring accurate chromosome orientation and segregation during cell division.

The Transmembrane Protein Semi1 Positions Gamete Nuclei for Reciprocal Fertilization in Tetrahymena
Summary: During sexual reproduction in the ciliate, Tetrahymena thermophila, cells of complementary mating type pair (“conjugate”) undergo simultaneous meiosis and fertilize each other.

A family case of fertile human 45,X,psu dic(15;Y) males [PDF]
We report on a familial case including four male probands from three generations with a 45,X,psu dic(15;Y)(p11.2;q12) karyotype. 45,X is usually associated with a female phenotype and only rarely with maleness, due to translocation of small Y chromosomal

PTBP1 enforces ATR-CHK1 signaling determining the potency of CDC7 inhibitors
Summary: CDC7 kinase is crucial for DNA replication initiation and fork processing. CDC7 inhibition mildly activates the ATR pathway, which further limits origin firing; however, to date the relationship between CDC7 and ATR remains controversial.

The Origin of a New Sex Chromosome by Introgression between Two Stickleback Fishes. [PDF]
Introgression is increasingly recognized as a source of genetic diversity that fuels adaptation. Its role in the evolution of sex chromosomes, however, is not well known. Here, we confirm the hypothesis that the Y chromosome in the ninespine stickleback,

Y chromosome functions in mammalian spermatogenesis
The mammalian Y chromosome is critical for male sex determination and spermatogenesis. However, linking each Y gene to specific aspects of male reproduction has been challenging.

A conserved filamentous assembly underlies the structure of the meiotic chromosome axis. [PDF]
The meiotic chromosome axis plays key roles in meiotic chromosome organization and recombination, yet the underlying protein components of this structure are highly diverged.
