Genomic Changes of Chagas Disease Vector, South America

Emerging Infectious Diseases, 2004
We analyzed the main karyologic changes that have occurred during the dispersion of Triatoma infestans, the main vector of Chagas disease. We identified two allopatric groups, named Andean and non-Andean.

Table_1_Mitotic Spindle Attachment to the Holocentric Chromosomes of Cuscuta europaea Does Not Correlate With the Distribution of CENH3 Chromatin.xlsx

, 2020
The centromere is the region on a chromosome where the kinetochore assembles and spindle microtubules attach during mitosis and meiosis. In the vast majority of eukaryotes, the centromere position is determined epigenetically by the presence of the ...

Chromosome and genome size variation in Luzula (Juncaceae), a genus with holocentric chromosomes

, 2012
The present study examines chromosome and genome size evolution in Luzula (woodrush; Juncaceae), a monocot genus with holocentric chromosomes. Detailed karyotypes and genome size estimates were obtained for seven Luzula spp., and these were combined with additional data from the literature to enable a comprehensive cytological analysis of the genus. So

Banding patterns of the holocentric chromosomes in some species of Heteroptera.

CYTOLOGIA, 1990
Spermatogonial metaphase chromosomes of Petillia patullicollis, Leptocorisa acuta and Ochrochira granulipes reveal C-bands, while G-bands are encountered in some chromosomes of Iphita limbata, Anoplocnemis phasiana and Leptocorisa acuta. The most frequent location of C-heterochromatin occurs in telomeric regions.

Meiotic chromosomes and nucleolar behavior in testicular cells of the grassland spittlebugs Deois flavopicta, Mahanarva fimbriolata and Notozulia entreriana (Hemiptera, Auchenorrhyncha)

Genetics and Molecular Biology, 2010
Spittlebugs annually infest pastures and cause severe damage, representing a serious problem for the tropical American beef cattle industry. Spittlebugs are an important biotic constraint to forage production and there is a lack of cytogenetic data for ...
