Anales del Jardín Botánico de Madrid, 2016 Artemisia herba-alba is a largely-distributed and often landscape-dominating taxon in arid areas of the Mediterranean and Irano-Turanian regions. In Algeria, in 2010 its communities covered 10% of the steppe territory, but its populations have been ...

Cytogenetic study and pollen viability of three populations of Diplotaxis harra (Brassicaceae) in Iran [PDF]
Journal of Cell and Molecular Research, 2014 In this study, we examined the chromosome number, detailed male meiosis, microsporogenesis, pollen fertility and distribution of cytotypes of Diplotaxis harra (Forssk.) Boiss. This is the first cytogenetic report of the taxon.

On the Order of Gene Distribution on Chromosomes Across the Animal Kingdom [PDF]
arXiv, 2019 Background. The large-scale pattern of distribution of genes on the chromosomes in the known animal genomes is not well characterized. We hypothesized that individual genes will be distributed on chromosomes in a mathematically ordered manner across the animal kingdom. Results.

Annals of Botany, 2012 BACKGROUND AND AIMS For 84 years, botanists have relied on calculating the highest common factor for series of haploid chromosome numbers to arrive at a so-called basic number, x.

Cell‐free DNA aneuploidy score as a dynamic early response marker in prostate cancer
Molecular Oncology, EarlyView.mFast‐SeqS‐based genome‐wide aneuploidy scores are concordant with aneuploidy scores obtained by whole genome sequencing from tumor tissue and can predict response to ARSI treatment at baseline and, at an early time point, to ARSI and taxanes. This assay can be easily performed at low cost and requires little input of cfDNA. Cell‐free circulating tumor

MEIOSIS: HOW TO HALVE THE CHROMOSOME NUMBER
Вавиловский журнал генетики и селекции, 2014 The notion of meiosis has been changed and refined for over a century since the discovery of this complicated way of cell division. Its success depends on precise time and space orchestration of many processes, such as chromosome replication, packaging ...

Cytogenetic study of two Solenanthus Ledeb. species (Boraginaceae) in Iran [PDF]
Journal of Cell and Molecular Research, 2013 Chromosome number, meiotic behavior, and pollen viability were analyzed in 2 species of genus Solenanthus, S. stamineus (Desf.) Wettst. and S. circinnatus Ledeb, from Iran. This report is the first cytogenetic analysis of these species.

Can entropy save bacteria? [PDF]
Suckjoon Jun and Andrew Wright, Nature Reviews Microbiology,
August issue (2010), 2008 This article presents a physical biology approach to understanding organization and segregation of bacterial chromosomes. The author uses a "piston" analogy for bacterial chromosomes in a cell, which leads to a phase diagram for the organization of two athermal chains confined in a closed geometry characterized by two length scales (length and width ...

Evolution; international journal of organic evolution, 2012 The effects of chromosome rearrangement on genome size are poorly understood. While chromosome duplications and deletions have predictable effects on genome size, chromosome fusion, fission, and translocation do not.

Molecular Oncology, EarlyView.MET variants in the N‐lobe of the kinase domain, found in hereditary papillary renal cell carcinoma, require ligand stimulation to promote cell transformation, in contrast to other RTK variants. This suggests that HGF expression in the microenvironment is important for tumor growth in such patients. Their sensitivity to MET inhibitors opens the way for
