Evolutionary diversification of Western Atlantic Bathygobius species based on cytogenetic, morphologic and DNA barcode data
(2016-03-01)
A number of fish groups, such as Gobiidae, are highly diversified and taxonomically complex. Extensive efforts are necessary to elucidate their cryptic diversity, since questions often arise about the phylogenetic aspects ...
Exploring karyotype diversity of Argentinian Guaranímaize landraces: Relationship among South American maize
(Public Library of Science, 2018-06)
In Argentina there are two different centers of maize diversity, the Northeastern (NEA) and the Northwestern (NWA) regions of the country. In NEA, morphological studies identified 15 landraces cultivated by the Guaraní ...
Karyotype asymmetry shapes diversity within the physaloids (Physalidinae, Physalideae, Solanaceae)
(Cambridge University Press, 2020-12)
Within the cosmopolitan family Solanaceae, Physalideae is the tribe with the highest generic diversity (30 genera and more than 200 species). This tribe embraces subtribe Physalidinae, in which phylogenetic relationships ...
Chromosomal changes and recent diversification in the Andean genus Jaborosa (Solanaceae)
(Oxford University Press, 2016-09)
With the purpose of discussing the evolutionary dynamics of the karyotypes and their relationship with key geological events, CMA/DAPI banding and FISH techniques were applied to metaphase chromosomes of 13 Jaborosa species ...
Karyotype studies in South American species of Solanum subgen. Leptostemonum (Solanaceae).
(Wiley Blackwell Publishing, Inc, 2006-07)
Mitotic chromosome numbers and karyotypes of 13 South American species (12 native and one naturalized) from four sections of Solanum subgen. Leptostemonum were studied. Chromosome numbers of S. acerifolium, S. aenictum, ...
Karyotypes of some species of Cestrum, Sessea, and Vestia (tribe Cestreae, Solanaceae)
(Univ Florence Botany Inst, 2006-12)
The somatic chromosomes of Cestrum bigibbosum Pittier, C. buxifolium Kunth, Sessea corymbosa Goudot ex Taylor and Phillips and Vestia foetida (Ruiz et Pav.) Hoffmanns, were examined by classical staining. The number 2n = ...
Chromosomal evolution of tribe Oryzomyini (Rodentia: Cricetidae: Sigmodontinae)
(2022-01-01)
Oryzomyini is the most diverse tribe of subfamily Sigmodontinae, comprising 30 genera and 147 extant species. Cytogenetic studies on Oryzomyini reflect this diversity, revealing an exceptional range of karyotype variability, ...
Phylogeny and chromosomal diversification in the Dichroplus elongatus species group (Orthoptera, Melanoplinae)
(2017-02-01)
In an attempt to track the chromosomal differentiation in the Dichroplus elongatus species group, we analyzed the karyotypes of four species with classical cytogenetic and mapping several multigene families through fluorescent ...
