Supernumerary chromosome variants in Dichroplus elongatus (Acrididae): Fluorescent banding and cline variation pattern
(BioOne, 2010-12)
Dichroplus elongatus is a South American grasshopper that shows simultaneous polymorphisms for B chromosomes and several supernumerary segments located in chromosome pairs S10, S9, and M6 (SS10, SS9 and SS6 respectively), ...
Kinetic activity of the sex chromosomes of Mormidea paupercula (Pentatomidae, Heteroptera)
(Czech Academy of Sciences, 2010-07)
InMormidea paupercula (n = 6 + XY in males), the presence of a CMA3-bright band in the telomeric regions on both sexchromosomes allowed the analysis of the kinetic activity of the sex univalents and XY pseudobivalent at ...
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 ...
Karyotype differentiation between Koelreuteria bipinnata and K. elegans subsp. formosana (Sapindaceae) based on chromosome banding patterns.
(Wiley Blackwell Publishing, Inc, 2005-12)
Koelreuteria Laxm., a genus in the tribe Koelreuterieae (Sapindaceae), includes three tree species that are widely recognized as having horticultural merit. The two more closely related species, K. bipinnata Franch. and ...
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 ...
Comparative cytogenetic analysis in Erythrolamprus snakes (Serpentes: Dipsadidae) from Argentina
(Academia Brasileira de Ciencias, 2018-04)
We described the karyotypes of five snake taxa from Argentina: Erythrolamprus almadensis, E. ceii, E. poecilogyrus caesius, E. p. schotti and E. p. sublineatus, and also intergrading individuals between the last two ...
Chromosomes of Cichlasoma istlanum (Perciformes: Cichlidae) and karyotype comparison of two presumed subspecies
(Universidad de Costa Rica, 1999)
Understanding the extensive hybridization in South American Nothofagus through karyotype analysis
(Oxford University Press, 2018-07)
Extensive phylogeographic and population studies in Nothofagus revealed that hybridization, introgression and plastid capture are common phenomena that have occurred throughout the evolutionary history of the genus. Here, ...
Incipient speciation in Calceolaria polyrhiza complex (Calceolariaceae): Cytogenetic analysis supports molecular and morphological data
(Taylor & Francis Ltd, 2021-06)
Calceolaria polyrhiza is a perennial herb distributed in southern South America. The species is highly polymorphic and includes four described morphotypes that were previously considered different species. We performed a ...
Evidence of the occurrence of structural chromosome changes at the initial diploid diversification of the autopolyploid Turnera sidoides L. (Passifloraceae) complex
(Natl Research Council Canada-n R C Research Press, 2015-11)
Turnera sidoides L. (x = 7) is an autopolyploid complex of obligate outcrossing perennial herbs. Includes five taxonomic subspecies and seven morphotypes in which different ploidy levels were found from diploid to octoploid. ...
