Cytogenetic studies in the genus Pentaschistis (Poaceae: Arundinoideae)

open access: yesBothalia: African Biodiversity & Conservation, 1998
Cytogenetic studies of 45 specimens, representing 16 taxa of the genus Pentaschistis (Nees) Spach confirmed two basic chromosome numbers (x = 7, 13) for the genus. Chromosome numbers for five species and one subspecies are described for the first time, i.

Architecture of metaphase chromosomes and chromosome scaffolds. [PDF]

open access: yesThe Journal of cell biology, 1983
We have developed procedures for depositing intact mitotic chromosomes and isolated residual scaffolds on electron microscope grids at controlled and reproducible levels of compaction. The chromosomes were isolated using a recently developed aqueous method. Our study has addressed two different aspects of chromosome structure.

Genetic control of isozymes in the primary gene pool Phaseolus lunatus L. [PDF]

open access: yesBiotechnologie, Agronomie, Société et Environnement, 1999
Suitable electrophoretic separation methods of 34 isozymes from 17 enzyme systems resolved in Phaseolus lunatus L. (Lima bean) were developed. Data from the migration of the staining zones indicated that three loci control EST, GPI, IDH and MDH ...

Complete and de novo assembly of the Leishmania braziliensis (M2904) genome

open access: yesMemorias do Instituto Oswaldo Cruz, 2018
Leishmania braziliensis is the etiological agent of American mucosal leishmaniasis, one of the most severe clinical forms of leishmaniasis. Here, we report the assembly of the L. braziliensis (M2904) genome into 35 continuous chromosomes.

Chromosomal analysis: an effective research tool in phylogenetics and taxonomy of parasitoid Hymenoptera [PDF]

open access: yesКавказский энтомологический бюллетень, 2015
A brief review of phylogenetic and taxonomic implications of chromosomal analysis of parasitoid Hymenoptera is given. Although karyotypic research of parasitoids is generally represented by studies using pre-existing phylogenetic reconstructions of ...

A new continuous cell line from the mosquito Psorophora confinnis (Diptera: Culicidae) and its susceptibility to infections with some arboviruses

open access: yesMemorias do Instituto Oswaldo Cruz, 2001
A new cell line, PC-0199-BR, was established from embryonated eggs of the mosquito Psorophora confinnis. To date (September 2000) it has had 62 continuous passages.
