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 ...
Differences and resemblances in banding patterns and ribosomal DNA distribution in four species of Paullinieae tribe (Sapindaceae)
(Univ Tokyo Cytologia, 2008-12)
The tribe Paullinieae (Sapindaceae) is exclusively neotropically distributed, and is characterized by apomorphic characters and considered a monophyletic natural group. Recently explored cytogenetical aspects suggest that ...
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 ...
POACEAE. Paspalum lilloi Hack.
(International Association for Plant Taxonomy, 2017-12)
Paspalum lilloi Hack. is an endemic species from Iguazú Falls. Karyomorphometric analyses and meiotic behaviour description are presented for the first time for the species. It showed unimodal and symmetrical karyotype (1A ...
Chromosome diversity in species of the genus Arachis, revealed by FISH and CMA/DAPI banding, and inferences about their karyotype differentiation
(Academia Brasileira de Ciencias, 2020-07)
The species of the genus Arachis (Leguminosae) are ordered into nine sections. The assignment of genome types in this genus has been based on cross-compatibility analysis and molecular cytogenetic studies. The latter has ...
Comparative study of mitotic chromosomes in two blowflies, Lucilia sericata and L. cluvia (Diptera, Calliphoridae), by C- and G-like banding patterns and rRNA loci, and implications for karyotype evolution
(Zoological Institute, 2015-03)
The karyotypes of Lucilia cluvia (Walker, 1849) and L. sericata (Meigen, 1826) from Argentina were characterized using conventional staining and the C- and G-like banding techniques. Besides, nucleolus organizer regions ...
Characterization of Brazilian accessions of wild Arachis species of section Arachis (Fabaceae) using heterochromatin detection and fluorescence in situ hybridization (FISH).
(Soc Brasil Genetica, 2013-07)
The cytogenetic characterization of Arachis species is useful for assessing the genomes present in this genus, for establishing the relationship among their representatives and for understanding the variability in the ...
Heterochromatin evolution in Arachis investigated through genome-wide analysis of repetitive DNA
(Springer, 2019-05)
Main conclusion: The most conspicuous difference among chromosomes and genomes in Arachis species, the patterns of heterochromatin, was mainly modeled by differential amplification of different members of one superfamily ...
