XY 1Y 2 chromosome system in Salinomys delicatus (Rodentia, Cricetidae)
(Springer, 2011-11)
Salinomys delicatus is considered a rare speciesdue to its restricted and patchy distribution, poor recordsand low abundances. It is also the phyllotine with thelowest known diploid chromosome number (2n = 18),however its ...
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 ...

First cytogenetic characterization of Loricaria simillima (Loricariidae, Siluriformes) from Paraná River (Argentina) with emphasis in cytotaxonomy of Loricaria
(Taylor & Francis, 2016-11-30)
This work aims to establish some cytogenetic characteristics of Loricaria simillima from Paraná River. The obtained results show that L. simillima has a 2n = 64 diploid number, with 12 metacentric, 12 sub-metacentric and ...
Sex chromosomes in the Vizcacheras’ White-lipped frog, Leptodactylus bufonius (Anura, Leptodactylidae)
(Academia Brasilera de Ciencias, 2021-06)
Cytogenetic analyses were performed on specimens of Leptodactylus bufonius from different localities in Argentina. Mitotic chromosomes were studied with Giemsa and differential staining techniques (Ag-NOR, C-banding, and ...
First report of B chromosomes in three neotropical thorny catfishes (Siluriformes, Doradidae)
(Pensoft, 2017-01-09)
The family Doradidae (Siluriformes) is an important group of fishes endemic to freshwater ecosystems in South America. Some cytogenetic studies have been conducted focused on the group; however, there are no reports on 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 ...
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, ...
Interstitial telomeric sequences in vertebrate chromosomes: Origin, function, instability and evolution
(Elsevier Science, 2017-07)
By definition, telomeric sequences are located at the very ends or terminal regions of chromosomes. However, several vertebrate species show blocks of (TTAGGG)n repeats present in non-terminal regions of chromosomes, the ...
