Large chromosomal structural variations between M. acuminata and M balbisiana and their consequences on chromosome recombination and segregation in a AAAB polyploidy context [PDF]

, 2017
Many banana cultivars are triploid interspecific hybrids between M. acuminata (Genome A, 2n=22) and M. balbisiana (Genome B, 2n=22). They included the important group of Plantain cooking bananas classified as AAB.

Centromere function in asymmetric cell division in Drosophila female and male germline stem cells

Open Biology, 2021
The centromere is the constricted chromosomal region required for the correct separation of the genetic material at cell division. The kinetochore protein complex assembles at the centromere and captures microtubules emanating from the centrosome to ...

Sex chromosome positions in human interphase nuclei as studied by in situ hybridization with chromosome specific DNA probes [PDF]

, 1984
Two cloned repetitive DNA probes, pXBR and CY1, which bind preferentially to specific regions of the human X and Y chromosome, respectively, were used to study the distribution of the sex chromosomes in human lymphocyte nuclei by in situ hybridization ...

STAG2 loss in Ewing sarcoma alters enhancer-promoter contacts dependent and independent of EWS::FLI1

EMBO Reports
Cohesin complexes carrying STAG1 or STAG2 organize the genome into chromatin loops. STAG2 loss-of-function mutations promote metastasis in Ewing sarcoma, a pediatric cancer driven by the fusion transcription factor EWS::FLI1. We integrated transcriptomic

Control of Smc Coiled Coil Architecture by the ATPase Heads Facilitates Targeting to Chromosomal ParB/parS and Release onto Flanking DNA

Cell Reports, 2016
Smc/ScpAB promotes chromosome segregation in prokaryotes, presumably by compacting and resolving nascent sister chromosomes. The underlying mechanisms, however, are poorly understood.

Rapid generation of chromosome-specific alphoid DNA probes using the polymerase chain reaction [PDF]

, 1992
Non-isotopic in situ hybridization of chromosome-specific alphoid DNA probes has become a potent tool in the study of numerical aberrations of specific human chromosomes at all stages of the cell cycle. In this paper, we describe approaches for the rapid

Subunit interactions and arrangements in the fission yeast Mis16–Mis18–Mis19 complex

Life Science Alliance, 2019
A structural study of the fission yeast Mis19 protein, required for centromere establishment, is presented together with data describing its interactions with functional partners Mis16 and Mis18. Centromeric chromatin in fission yeast is distinguished by

Dynamic chromatin regulatory programs during embryogenesis of hexaploid wheat

Genome Biology, 2023
Background Plant and animal embryogenesis have conserved and distinct features. Cell fate transitions occur during embryogenesis in both plants and animals. The epigenomic processes regulating plant embryogenesis remain largely elusive.

Cytological and molecular characterization of wheat lines with Thinopyrum intermedium chromosome additions, substitutions and translocations resistant to barley yellow dwarf virus [PDF]

, 1999
Barley yellow dwarf virus (BYDV) is the most serious viral disease affecting wheat and genes for BYDV resistance have not been found in wheat. BYDV-resistant alien addition and alien substitution lines produced from a wheat × Thinopyrum intermedium ...

Chromosome orientation [PDF]

The Journal of Cell Biology, 2007
Precise chromosome segregation during cell division results from the attachment of chromosomes to microtubules emanating from both poles of the spindle apparatus. The molecular machinery involved in establishing and maintaining properly oriented microtubule attachments remains murky.
