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 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 ...
Highly GC-rich heterochromatin in chili peppers (Capsicum-Solanaceae): A cytogenetic and molecular characterization
(Elsevier, 2018-08)
Capsicum comprises 35 species of chili peppers and five of them are cultivated worldwide as spices or vegetables. Diploid karyotypes based in x = 12 and x = 13 are common in Capsicum and the constitutive heterochromatin ...
Telomeric heterochromatin, seeds and meiotic characteristics in two tricepiro lines
(Instituto de Botánica Darwinion, 2011-12)
Al cruzar un triticale hexaploide (2n=6x=42) y un trigopiro octoploide (2n=8x=56) se obtuvo, en 1972, un híbrido denominado tricepiro. Entre las líneas que se lograron están tricepiro Don René INTA que posee semillas ...
Genome size and karyotype diversity in Solanum sect. Acanthophora (Solanaceae)
(Springer Wien, 2013-06)
Abstract In order to study the evolution of different cytogenetic characters in species of Solanum sect. Acanthophora in relationship to the known phylogeny for this group, the following techniques were used: CMA/DAPI ...
Chromosome differentiation in three species of Leptostemonum (Solanum, Solanaceae) endemic to Oceanic Islands
(Sociedad Argentina de Botánica, 2016-12)
The chromosomes of Solanum nelsonii, S. sandwicense (endemic to the Hawaii islands) and S. vespertilio (from the Canary islands) were studied by means of classical staining, CMA/DAPI banding and FISH with probes for the ...
Heterochromatin characterization and ribosomal gene location in two monotypic genera of bloodsucker bugs (Cimicidae, Heteroptera) with holokinetic chromosomes and achiasmatic male meiosis
(Cambridge University Press, 2014-12)
Members of the family Cimicidae (Heteroptera: Cimicomorpha) are temporary bloodsuckers on birds and bats as primary hosts and humans as secondary hosts. Acanthocrios furnarii (2n=12=10+XY, male) and Psitticimex uritui ...
Chromosome evolution in the cosmopolitan genus Lycium (Solanaceae)
(International Association for Plant Taxonomy, 2020-04)
Lycium is the only member of tribe Lycieae (Solanoideae, Solanaceae), and it has a cosmopolitan distribution with its greatest diversity in southern South America, southern Africa, and southwestern North America. To date, ...
Differential contribution of HP1 proteins to DNA end resection and homology-directed repair
(Taylor & Francis, 2013-02)
Heterochromatin protein 1 paralogs (HP1α, β and γ in mammals) are not only central in heterochromatin organization, but have also been linked to transcriptional activation at euchromatic regions, maintenance of telomere ...
