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 ...
Distribution of constitutive heterochromatin in two species of triatomines: Triatoma lenti Sherlock and Serafim (1967) and Triatoma sherlocki Papa, Jurberg, Carcavallo, Cerqueira & Barata (2002)
(2013-01-01)
Triatoma lenti and Triatoma sherlocki are hemipterans that belong to the brasiliensis subcomplex. In triatomines, the constitutive heterochromatin pattern is species-specific and allows, in many cases, for the grouping of ...

The contrasting role of heterochromatin in the differentiation of sex chromosomes: an overview from Neotropical fishes
(WILEY-BLACKWELLMALDEN, 2012)
During the evolutionary process of the sex chromosomes, a general principle that arises is that cessation or a partial restriction of recombination between the sex chromosome pair is necessary. Data from phylogenetically ...
Molecular cytogenetic analysis of heterochromatin in the chromosomes of tilapia, Oreochromis niloticus (Teleostei : Cichlidae)
(Kluwer Academic Publ, 1998-04-01)
The structure of the heterochromatic bands in mitotic chromosomes of the important tropical aquaculture species of tilapia, Oreochromis niloticus, was investigated by the combination of the C-banding technique, chromosomal ...
The new world artemia species a-franciscana and a-persimilis are highly differentiated for chromosome size and heterochromatin content
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
Cytogenetics of three Brazilian species of Eleutherodactylus (Anura, Leptodactylidae) with 22 chromosomes and re-analysis of multiple translocations in E-binotatus
(Soc Brasil GeneticaRibeirao PretBrasil, 2004)
