Cytogenetic study and pollen viability of four populations of Trigonella [PDF]

Journal of Cell and Molecular Research, 2011
In the present paper, the cytogenetic study including meiotic chromosome number and behavior along with pollen viability were performed in 4 populations of Trigonella spruneriana Boiss. This is the first cytogenetic report of the taxon.

The Impact of Reconstruction Methods, Phylogenetic Uncertainty and Branch Lengths on Inference of Chromosome Number Evolution in American Daisies (Melampodium, Asteraceae)

PLoS ONE, 2016
Chromosome number change (polyploidy and dysploidy) plays an important role in plant diversification and speciation. Investigating chromosome number evolution commonly entails ancestral state reconstruction performed within a phylogenetic framework ...

Copy number variation screen identifies a rare de novo deletion at chromosome 15q13.1-13.3 in a child with language impairment

, 2015
A significant proportion of children (up to 7% in the UK) present with pronounced language difficulties that cannot be explained by obvious causes like other neurological and medical conditions.

On the regulation of chromosome segregation in human cells : implications of Bub1 Kinase inhibition during cell division [PDF]

, 2015
The maintenance of correct chromosome number (euploidy) during cell division is essential for health. Loss of euploidy is observed in most cancers and is linked to tumorigenesis.

Cytomolecular identification of individual wheat-wheat chromosome arm associations in wheat-rye hybrids

, 2013
Chromosome pairing in the meiotic metaphase I of wheatrye hybrids has been characterized by sequential genomic and fluorescent in situ hybridization allowing not only the discrimination of wheat and rye chromosomes, but also the identification of the

Deep Sequencing of FLT3‐ITD Enables Response Evaluation and Post‐Treatment Monitoring in Childhood AML: An Exploratory Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background An internal tandem duplication in the gene encoding Fms‐like tyrosine kinase 3 (FLT3‐ITD) is associated with high relapse risk and poor prognosis in acute myeloid leukemia (AML) and plays a crucial role in treatment decisions. Measurable residual disease (MRD) analysis of FLT3‐ITD during and after treatment has shown prognostic ...

Recombination, chromosome number and eusociality in the Hymenoptera

Journal of Evolutionary Biology, 2015
Extraordinarily high rates of recombination have been observed in some eusocial species. The most popular explanation is that increased recombination increases genetic variation among workers, which in turn increases colony performance, for example by ...

A genetic basis for a postmeiotic X versus Y chromosome intragenomic conflict in the mouse. [PDF]

, 2012
Intragenomic conflicts arise when a genetic element favours its own transmission to the detriment of others. Conflicts over sex chromosome transmission are expected to have influenced genome structure, gene regulation, and speciation.
