Cytogenetic Study of Holocentric Chromosomes in Three Species of Triatomines (Heteroptera, Reduvidae)

CYTOLOGIA, 2004
In the present work, spermatogenesis was analyzed in 3 species of the genus Triatoma (T. platensis, T. proctata, T. tibiamaculata). Lacto-acetic orcein staining was used in order to investigate chromosomal meiotic behavior of these species. It allowed the identification of the T. tibiamaculata karyotype (20, X1X2Y), the observation that in T.

Cytogenetic and molecular characterization of the MBSAT1 satellite DNA in holokinetic chromosomes of the cabbage moth, Mamestra brassicae (Lepidoptera) [PDF]

, 2003
Digestion of Mamestra brassicae DNA with DraI produced a prominent fragment of approximately 200 by and a ladder of electrophoretic bands with molecular weights which are a multiple of 200 bp.

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.

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 ...

Characterizing the 3D organization of holocentric chromosomes in Bombyx mori

, 2022
L'organisation du génome dans le noyau cellulaire a été observée et décrite dans différents organismes depuis plus de 140 ans. La plupart des organismes où cela a été fait sont monocentriques, c’est-à-dire dont les chromosomes n’ont qu’un seul centromère.
