Heterochromatin differentiation in holocentric chromosomes of Rhynchospora (Cyperaceae) [PDF]

open access: yesGenetics and Molecular Biology, 2000
Holocentric chromosomes of six species of Rhynchospora, R. ciliata, R. pubera, R. riparia and R. barbata (2n = 10), R. nervosa (2n = 30) and R. globosa (2n = 36), were stained with CMA3/DAPI fluorochromes or treated with C-banding and sequentially ...

Chromosome number evolves at equal rates in holocentric and monocentric clades.

open access: yesPLoS Genetics, 2020
Despite the fundamental role of centromeres two different types are observed across plants and animals. Monocentric chromosomes possess a single region that function as the centromere while in holocentric chromosomes centromere activity is spread across ...

Unique territorial and compartmental organization of chromosomes in the holocentric silkworm [PDF]

open access: yesThe EMBO Journal, 2023
Hallmarks of multicellular eukaryotic genome organization are chromosome territories, compartments, and loop-extrusion-mediated structures, including TADs. However, these have mainly been observed in model organisms, and most eukaryotes remain unexplored.

Holocentric chromosomes in animals and plants: what do we know about these points outside the curve?

open access: yesEvidência, 2023
Usually, members of the Eukarya domain have kinetochores grouped at a single point, characterizing monocentric chromosomes. However, in some taxa the protein apparatus that composes the kinetochore is distributed continuously or discretely along the ...

A holocentric twist to chromosomal speciation? [PDF]

open access: yesTrends in Ecology & Evolution, 2022
Chromosomal rearrangements trigger speciation by acting as barriers to gene flow. However, the underlying theory was developed with monocentric chromosomes in mind.

A satellite explosion in the genome of holocentric nematodes. [PDF]

open access: yesPLoS ONE, 2013
Centromere sequences in the genome are associated with the formation of kinetochores, where spindle microtubules grow in mitosis. Centromere sequences usually have long tandem repeats (satellites).

Holocentric Chromosomes [PDF]

open access: yes, 2001
Macromolecular structures called kinetochores attach and move chromosomes within the spindle during chromosome segregation. Using electron microscopy, we identified a structure on the holocentric mitotic and meiotic chromosomes of Caenorhabditis elegans ...

Analysis of insect holocentric chromosomes by atomic force microscopy [PDF]

open access: yesHereditas, 2003
In order to go in depth into the analysis of holocentric chromosome structure, atomic force microscopy (AFM) was applied to metaphase plates of the aphid Megoura viciae.

Cytogenetic characterization of telomeres in the holocentric chromosomes of the lepidopteran Mamestra brassicae [PDF]

open access: yesChromosome Research, 2002
Telomeres of the Mamestra brassica holocentric chromosomes were studied by Southern blotting, in-situ hybridization and Bal31 assay evidencing the presence of the telomeric (TTAGG)(n) repeat.
