Banding of Oedionychina (Coleoptera:Alticinae) Chromosomes: C- and Ag-bandsTítulo en español
(University of Puerto Rico Mayagüez Campus Agricultural Experiment Station, 1983)
Possible origin of polymorphism for chromosome number in the assassin bug Zelurus femoralis longispinis (Reduviidae: Reduviinae)
(Wiley Blackwell Publishing, Inc, 2013-10)
In this study, we analysed a population of Zelurus femoralis longispinis polymorphic for chromosomal number. The fundamental karyotype of this subspecies is 2n = 22 = 20A + XY (male), but individuals with 2n = 23 = 20A + ...
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 ...
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 ...
C-banding, fluorescent staining and NOR location in holokinetic chromosomes of bugs of the Neotropical genus Antiteuchus (Heteroptera: Pentatomidae: Discocephalinae)
(Czech Academy of Sciences, 2006-12)
Different cytogenetic techniques including C-banding, base-specific fluorochromes and silver nitrate staining were used to compare the karyotypes of three species of bugs, representatives of the Neotropical genus Antiteuchus, ...
Supernumerary chromosome variants in Dichroplus elongatus (Acrididae): Fluorescent banding and cline variation pattern
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), ...
A karyotype comparison between two species of bordered plant bugs (hemiptera, heteroptera, largidae) by conventional chromosome staining, c-banding and rDNA-FISH
(Zoological Institute, 2017-04)
A cytogenetic characterization, including heterochromatin content, and the analysis of the location of rDNA genes, was performed in Largus fasciatus Blanchard, 1843 and L. Rufipennis Laporte, 1832. Mitotic and meiotic ...
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 ...
Cytogenetic studies in herbertia sw. (iridaceae)
(University Florence Botany Institute, 2009-12)
Conventional Feulgen staining, CMA/DAPI banding and FISH with 18-5.8-26S rDNA probe were used to determine chromosome numbers, karyotypes and physical position of GC or AT rich heterochromatin and rDNA sites in three South ...
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 ...
