Chromosome puzzle in the southernmost populations of the medically important scorpion Tityus bahiensis (Perty 1833) (Buthidae), a polymorphic species with striking structural rearrangements
(Elsevier Gmbh, 2020-09)
The scorpion Tityus bahiensis is the most common scorpion species of medical importance with sexual reproduction in South America. Many of the populations cytogenetically studied so far are polymorphic both for chromosome ...
Cytogenetic characterization of Diachasmimorpha longicaudata (Hymenoptera: Braconidae), a parasitoid wasp used as a biological control agent
(Czech Academy of Sciences, 2013-07)
Diachasmimorpha longicaudata (Hymenoptera: Braconidae) is a parasitoid wasp widely used in the biological control of fruit flies. In this paper, we present a detailed analysis of the karyotype of this species based on the ...
The new world artemia species a-franciscana and a-persimilis are highly differentiated for chromosome size and heterochromatin contentHEREDITAS

Sex chromosomes in the Vizcacheras’ White-lipped frog, Leptodactylus bufonius (Anura, Leptodactylidae)
(Academia Brasilera de Ciencias, 2021-06)
Cytogenetic analyses were performed on specimens of Leptodactylus bufonius from different localities in Argentina. Mitotic chromosomes were studied with Giemsa and differential staining techniques (Ag-NOR, C-banding, and ...
Commelina Platyphylla
(International Association for Plant Taxonomy, 2010-12)
Commelina platyphylla is a diploid species widely distributed in South America, representing a convenient model for karyological study. Different classical and molecular cytogenetics techniques were applied in order to ...
Characterization of Brazilian accessions of wild Arachis species of section Arachis (Fabaceae) using heterochromatin detection and fluorescence in situ hybridization (FISH).
(Soc Brasil Genetica, 2013-07)
The cytogenetic characterization of Arachis species is useful for assessing the genomes present in this genus, for establishing the relationship among their representatives and for understanding the variability in the ...
POACEAE. Paspalum lilloi Hack.
(International Association for Plant Taxonomy, 2017-12)
Paspalum lilloi Hack. is an endemic species from Iguazú Falls. Karyomorphometric analyses and meiotic behaviour description are presented for the first time for the species. It showed unimodal and symmetrical karyotype (1A ...
Male meiosis, heterochromatin characterization and chromosomal location of rDNA in Microtomus lunifer (Berg, 1900) (Hemiptera: Reduviidae: Hammacerinae)
(Pensoft Publishers, 2011-05)
In the present work, we analysed the male meiosis, the content and distribution of heterochromatin and the number and location of nucleolus organizing regions in Microtomus lunifer (Berg, 1900) by means of standard technique, ...
Heterochromatin evolution in Arachis investigated through genome-wide analysis of repetitive DNA
(Springer, 2019-05)
Main conclusion: The most conspicuous difference among chromosomes and genomes in Arachis species, the patterns of heterochromatin, was mainly modeled by differential amplification of different members of one superfamily ...
"Alteraciones citogenéticas en pacientes con diagnóstico de infertilidad en Lima, Perú "
(Sociedad Chilena de Obstetricia y GinecologiaCL, 2022-06-09)
"Introducción: La infertilidad es una enfermedad multicausal y el componente genético representa uno de sus principales eventos. Si bien la distribución de la infertilidad puede variar entre poblaciones, las parejas de los ...
