A Dictionary of Genetics
Eustigmatophyta, Labyrinthulomycota, chromocenter a central amorphous mass
found in the nuclei of larval salivary gland cells of Drosophila. Since the
chromocenter results from the fusion of the heterochromatic elements that
surround the ...

D. The Chromocenter and Other Heterochromatin The chromocenter is a diffuse
region composed of the fused pericentric regions of all of the chromosomes.
Heitz (1934) concluded that this region contained the heterochromatin that
surrounds ...
but is not itself present in early round spermatids (Martianov et al., 2002). It has
been suggested that, in spermatocytes, TBPL1 might regulate the transcription of
factors required for chromocenter formation. Loss of high mobility group box 2 ...

Nuclear Cytology in Relation to Development
The polytene chromosome cells of some Drosophila species possess a
chromocenter which consists of the associated kinetochore regions of the
chromosomes, the heterochromatic arms of the X chromosomes and the entire Y.
The ...
Laser scanning confocal microscopy, followed by three dimensional
reconstruction, demonstrated83 that the human sperm chromocenter is located at
the central portion of the nucleus (Figure 4). The internal structure of the
chromocenter is ...
Each of the four types of chromosome are attached to the chromocenter near
their centromeres. The X and Y and chromosome 4 are telocentric, and
chromosomes 2 and 3 are metacentric. Therefore, chromosomes 2 and 3 have
two arms that ...

Evolution and Impact of Transposable Elements
Two cytological domains of heterochromatin can be distinguished in the
chromocenter (Heitz, 1934): Q-heterochromatin, which corresponds to a small
compact region located in the middle of the chromocenter and undergoes little ...

Advances in Chromatin Research and Application: 2013 Edition
in different triatomini species, the aim of this study was to determine the
contribution of AT-, GC-, and methylated cytidine-rich DNA in the chromocenter
as well as in euchromatin of Malpighian tubule cell nuclei of P. megistus in
comparison ...
