strigosa, but were markedly different from the heterochromatic
karyotypes of C-genome Av.
In addition, this species also displays a polymorphism for extra heterochromatic
segments in chromosomes S10 and S11 (Shaw 1970, 1971a, b; Jones 1971; see Fig.
Enhancement of the chromosomes by pseudocoloration and enlargement of the images enable the edges of the chromosomes and the heterochromatic
bands to be distinguished for identification and measurement.
The karyotype of the African Population germplasm was chosen by our laboratory as the reference karyotype for alfalfa because in preliminary studies (Bauchan and Hossain, 1998), of all of the nine germplasm sources, African Population contained the largest number of heterochromatic
bands and represents the best fit to the C-banding pattern observed in diploid of M.
Nuclei of the Schwann cells were moderately heterochromatic
(2015) Neurospora importin [alpha] is required for normal heterochromatic
formation and DNA methylation.
The X aneuploidy could indirectly alter gene expression genome wide through epigenetic effects; for example, the presence of an extra heterochromatic
chromosome might act as a sink for specific protein complexes  and may be responsible for the phenotypic features of Klinefelter's syndrome .
The long arm of chromosome 11 has 5 bands, whereas the long arm of chromosome 9 has 4 bands because although the chromosomes are similar in length, 11q is longer than 9q when the 9q heterochromatic
region is excluded.
In previous studies, we reported that Nesprin-2 interacts with chromatin; in particular centromeric and other heterochromatic
reads were enriched in the ChIP-seq data .
The instrument employed was the mapcat SF[TM] , a heterochromatic
flicker photometer that was used in a customized mode (cHFP).
HP1y is situated to both heterochromatic
and euchromatic regions .
At the cytological level, heterochromatic
DNA is traced as condensed chromatin blocks throughout the cell cycle, except during replication in the late S-phase ; the replication of euchromatic gene-rich DNA occurs earlier in the S-phase.
