What do we know about the heterochromatin of capuchin monkeys (Cebus: Platyrrhini)?
(Wiley Blackwell Publishing, Inc, 2018-01)
Cytogenetic studies in Cebus spp. have highlighted a peculiar genomic feature: the presence of conspicuous regions of extracentromeric heterochromatin distributed throughout the karyotype. This study investigates the ...
Karyotype characterization of five Brazilian species of Echinodorus (Alismataceae) with chromosomal banding and 45S rDNA FISH
(Springer WienViennaAustria, 2006)
CRITICAL ELECTROLYTE CONCENTRATION AND DISPERSION OF BIREFRINGENCE IN HETEROCHROMATIN AND EUCHROMATIN OF COPPER SULFATE-TREATED SPECIMENS OF TRIATOMA-INFESTANS KLUG
(Gustav Fischer Verlag JenaJenaAlemanha, 1994)
Distribution of constitutive heterochromatin in Triatoma melanocephala (Hemiptera, Triatominae)
(Funpec-editora, 2014-01-01)
In principle, Triatoma melanocephala was included in the Brasiliensis subcomplex on the basis of morphological parameters and geographical layout, since there were no other relevant data available in the literature. On the ...
Physical mapping of 18S rDNA and heterochromatin in species of family Lygaeidae (Hemiptera: Heteroptera)
(Funpec-editora, 2014-01-01)
Analyses conducted using repetitive DNAs have contributed to better understanding the chromosome structure and evolution of several species of insects. There are few data on the organization, localization, and evolutionary ...
Karyotype characterization and evolution in South American species of Lathyrus (Notolathyrus, Leguminosae) evidenced by heterochromatin and rDNA mapping
(Springer Tokyo, 2015-10)
Notolathyrus is a section of South American endemic species of the genus Lathyrus. The origin, phylogenetic relationship and delimitation of some species are still controversial. The present study provides an exhaustive ...
Chromosome painting of Z and W sex chromosomes in Characidium (Characiformes, Crenuchidae)
(2013-01-24)
Some species of the genus Characidium have heteromorphic ZZ/ZW sex chromosomes with a totally heterochromatic W chromosome. Methods for chromosome microdissection associated with chromosome painting have become important ...
Chromosomal organization of the 18S and 5S rRNAs and histone H3 genes in Scarabaeinae coleopterans: insights into the evolutionary dynamics of multigene families and heterochromatin
(Biomed Central Ltd., 2011-10-15)
Background: Scarabaeinae beetles show a high level of macro-chromosomal variability, although the karyotypic organization of heterochromatin and multigene families (rDNAs and histone genes) is poorly understood in this ...
