Molecular control of animal cell cytokinesis
(Nature Publishing Group, 2012)
Imidacloprid modifies the mitotic kinetics and causes both aneugenic and clastogenic effects in the macrophyte Bidens laevis L.
(Elsevier, 2019-07)
Imidacloprid (IMI) is a neonicotinoid insecticide widely used in agricultural activities all around the world. This compound is transported from croplands to surrounding freshwater ecosystems, producing adverse effects on ...
Genetic instability induced by low doses of x-rays in hamster cells
(Taylor & Francis Ltd, 2007-12)
Purpose: Genomic instability involves time delayed events and can be manifested as elevated rates of heritable changes in the progeny of irradiated cells. To study the induction of chromosomal instability by very low doses ...
Meiotic irregularities in Alstroemeria andina var. Venustula (Alstroemeriaceae)
(Acad Sinica, 2007-12)
Alstroemeria andina Phil. var. venustula (Phil.) M. Muñoz (sub nom. A. andina Phil. subsp. venustula (Phil.) Ehr. Bayer) is a perennial, small herb, 5-16 cm tall, that occurs mainly at 2,800-3,700 meters above sea level, ...
Meiotic behaviour and B chromosomes in Argentine populations of Chrysolaena verbascifolia (Vernonieae: Asteraceae)
(Taylor and Francis Ltd., 2017-01)
Four populations of Chrysolaena verbascifolia (Vernonieae: Asteraceae) from localities in Argentina were cytologically analysed for meiotic behaviour and pollen viability. This is the first meiotic analysis in the species. ...
Karyotype evolution in progress: A new diploid number in Belostoma candidulum (Heteroptera: Belostomatidae) from Argentina leading to new insights into its ecology and evolution
(Czech Academy of Sciences, 2014-05)
A novel chromosome complement (2n = 14 = 12 + XY/XX; male/female sex chromosomes), male meiosis behaviour, heterochromatin characterization, and frequency and distribution of chiasmata are described for the first time in ...
The significance of cytogenetics for the study of karyotype evolution and taxonomy of water bugs (Heteroptera, Belostomatidae) native to Argentina
(Zoological Institute, 2013-04)
Male meiosis behaviour and heterochromatin characterization of three big water bug species were studied. Belostoma dentatum (Mayr, 1863), B. elongatum Montandon, 1908 and B. gestroi Montandon, 1903 possess 2n = 26 + X1X2Y ...
Genotoxicity evaluation of the insecticide endosulfan in the wetland macrophyte Bidens laevis L.
(Elsevier, 2008-06)
The frequency of micronuclei (MN) and chromosome aberrations in anaphase telophase (CAAT) was determined in root tips of the wetland macrophyte Bidens laevis exposed to environmentally relevant concentrations of endosulfan ...
Induction of microtubule damage in Allium cepa meristematic cells by pharmaceutical formulations of thiabendazole and griseofulvin
(Elsevier Science, 2014-09)
Microtubules (MT) are formed by the assembly of - and -tubulins and MT-associated proteins. We characterized the effects of pharmaceutical formulations containing the microtubule disruptors thiabendazole (TBZ) and griseofulvin ...
Cytogenetic and microtubule array effects of the zineb-containing commercial fungicide formulation Azzurro ® on meristematic root cells of Allium cepa L.
(Elsevier, 2012-02)
Zineb [ethylene bis(dithiocarbamate) zinc] is a widely employed foliar fungicide for agricultural and industrial applications. Allium cepa L. is a reliable model for the assessment of xenobiotic genotoxicity and cytotoxicity. ...
