Cytogenetic analyses in three species of Moenkhausia Eigenmann, 1903 (Characiformes, Characidae) from Upper Paraná River (Misiones, Argentina)
(University Florence Botany Institute, 2022-03)
Moenkhausia Eigenmann, 1903 is one of the most diverse genera within Characidae, being an important component of the Neotropical fish fauna. Three members of this genus were cytogenetically analyzed: M. dichroura Kner, ...
Physical mapping of the 5S and 18S-25S rRNA genes by FISH as evidence that Arachis duranensis and A. ipaensis are the wild diploid progenitors of A. hypogaea (Leguminosae)
(Botanical Society of America, 2004-09)
The 5S and the 18S-25S rRNA genes were physically mapped by fluorescent in situ hybridization (FISH) in all botanical varieties of cultivated peanut Arachis hypogaea (2n = 4x = 40), in the wild tetraploid A. monticola, and ...
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 ...
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 ...
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 ...
Sex chromosomes in mitotic and polytene tissues of Anastrepha fraterculus (Diptera, Tephritidae) from Argentina: a review
(Pensoft Publishers, 2015-11)
Cytogenetics, which is considered a fundamental tool to understand basic genetic and genomic issues of species, has greatly contributed to the description of polymorphisms both at inter- and intra-specific level. In fact, ...
Chromosomal variation in Argentine populations of Akodon montensis Thomas, 1913 (Rodentia, Cricetidae, Sigmodontinae)
(Zoological Inst, 2016-02-02)
The genus Akodon Meyen, 1833 is one of the most species-rich among sigmodontine rodents and has great chromosome variability. Akodon montensis has a relatively broad distribution in South America, and Argentine populations ...
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 ...
Cytogenetics of tuna in Argentina (two forms of Opuntia ficus-indica (L.) Mill. and O. robusta J. C. Wendl., Cactaceae)
(Springer, 2020-03-03)
Opuntia ficus-indica (L.) Mill. f. ficus-indica (yellow tuna, cordobesa orange tuna, italiana orange tuna, salteña tuna) and f. amyclaea (white tuna, reddish tuna) and O. robusta J. C. Wendl. (cuaresma tuna) are extensively ...
