Composition of constitutive heterochromatin of Pseudonannolene strinatii Mauriès, 1974 (Diplopoda, Spirostreptida) analyzed by AT/CG specific fluorochromes.
(2005-12-30)
Triple staining with fluorochromes (DA/DAPI/CMA) and C-banding were used to characterize the composition of Pseudonannolene strinatii heterochromatin. C-banding showed C+ bands of different labeling intensity on chromosomes ...

Evolutionary dynamics of heterochromatin in the genome of Dichotomius beetles based on chromosomal analysis
(Springer, 2011-03-01)
We comparatively analyzed six Dichotomius species (Coleoptera: Scarabainae) through cytogenetic methods and mitochondrial genes sequencing in the aim to identify patterns of chromosomal evolution and heterochromatin ...

Similarity of heterochromatic regions in the stingless bees (Hymenoptera: Meliponini) revealed by chromosome painting
(Univ Florence Botany Inst, 2014-09-01)
Most Meliponini share a distinctive pattern of heterochromatin distribution in relation to other bees. In general, they present one euchromatic and one heterochromatic chromosome arm, a feature explained by minimum interaction ...
The extensive amplification of heterochromatin in Melipona bees revealed by high throughput genomic and chromosomal analysis
(2021-01-01)
Satellite DNAs (satDNAs) and transposable elements (TEs) are among the main components of constitutive heterochromatin (c-heterochromatin) and are related to their functionality, dynamics, and evolution. A peculiar case ...
Karyotype and NOR conservatism with heterochromatin reorganization in Neotropical Bryconids
(1996-01-01)
Cytogenetic studies on Bryconid fishes have shown the occurrence of karyotype and NOR conservatism and heterochromatin reorganization. The present data on three species representative of the migratory genus Brycon corroborate ...
