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 ...

High resolution physical mapping of single gene fragments on pachytene chromosome 4 and 7 of Rosa [PDF]

open access: yes, 2015
Background: Rosaceae is a family containing many economically important fruit and ornamental species. Although fluorescence in situ hybridization (FISH)-based physical mapping of plant genomes is a valuable tool for map-based cloning, comparative ...

B Chromosomes – A Matter of Chromosome Drive

open access: yesFrontiers in Plant Science, 2017
B chromosomes are supernumerary chromosomes which are often preferentially inherited, deviating from usual Mendelian segregation. The balance between the so-called chromosome drive and the negative effects that the presence of Bs applies on the fitness ...

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.

SCREENING FOR BIOMORPHOLOGICAL AND CYTOGENETIC FEATURES OF POLEMONIUM CAERULEUM L. AFTER COLCHICINE APPLICATION

open access: yesSiberian Journal of Life Sciences and Agriculture, 2023
Background. Currently, it is quite relevant in breeding to create varieties with high yields of raw materials and the content of biologically active compounds. This work aim is to identify promising forms of P. caeruleum L. is for further inclusion in

Why genes evolve faster on secondary chromosomes in bacteria [PDF]

open access: yes, 2010
In bacterial genomes composed of more than one chromosome, one replicon is typically larger, harbors more essential genes than the others, and is considered primary.

Rabl's model of the interphase chromosome arrangement tested in Chinise hamster cells by premature chromosome condensation and laser-UV-microbeam experiments [PDF]

open access: yes, 1982
In 1885 Carl Rabl published his theory on the internal structure of the interphase nucleus. We have tested two predictions of this theory in fibroblasts grown in vitro from a female Chinese hamster, namely (1) the Rabl-orientation of interphase ...

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots

open access: yesFEBS Letters, EarlyView.
This study identifies a gene encoding a transmembrane protein, MIC, which contributes to the reduction of shoot Fe content observed in plants under elevated CO2. MIC is a putative Fe transporter localized to the Golgi and endosomal compartments. Its post‐translational regulation in roots may represent a potential target for improving plant nutrition ...

Analysis of chromosome positions in the interphase nucleus of Chinese hamster cells by laser-UV-microirradiation experiments [PDF]

open access: yes, 1982
Unsynchronized cells of an essentially diploid strain of female Chinese hamster cells derived from lung tissue (CHL) were laser-UV-microirradiated (=257 nm) in the nucleus either at its central part or at its periphery.
