Reduced activity of Arabidopsis chromosome-cohesion regulator gene CTF7/ECO1 alters cytosine methylation status and retrotransposon expression
(2015-05-01)
Multicellular organisms such as higher plants require timely regulation of DNA replication and cell division to grow and develop. Recent work in Arabidopsis has shown that chromosome segregation during meiosis and mitosis ...
The Opposing Actions of Arabidopsis CHROMOSOME TRANSMISSION FIDELITY7 and WINGS APART-LIKE1 and 2 Differ in Mitotic and Meiotic Cells
(2016-02-01)
Sister chromatid cohesion, which is mediated by the cohesin complex, is essential for the proper segregation of chromosomes during mitosis and meiosis. Stable binding of cohesin with chromosomes is regulated in part by the ...
In favor of establishment: chromatid cohesion in plants
(2017-05-23)
In eukaryotic organisms, the correct regulation of sister chromatid cohesion, whereby sister chromatids are paired and held together, is essential for accurate segregation of the sister chromatids and homologous chromosomes ...
Arabidopsis CHROMOSOME TRANSMISSION FIDELITY 7 (AtCTF7/ECO1) is required for DNA repair, mitosis and meiosis
(The Plant Journal 75: 927–940, 2013-06-10)
The proper transmission of DNA in dividing cells is crucial for the survival of eukaryotic organisms. During cell division, faithful segregation of replicated chromosomes requires their tight attachment, known as sister ...
A MICROSTRAIN COMPARISON OF PASSIVELY FITTING SCREW-RETAINED AND CEMENTED TITANIUM FRAMEWORKS
(Elsevier B.V., 2014-10-01)
Statement of problem. An imprecise fit between frameworks and supporting dental implants in loaded protocols increases the strain transferred to the periimplant bone, which may impair healing or generate microgaps.Purpose. ...
Potential to Increase Productivity and Sustainability in Argentinean Agriculture with Controlled Traffic Farming: A Short Discussion
(De Gruyter, 2015-03)
Drivers for and potential barriers against adoption of controlled traffic farming (CTF) systems in Argentina are reviewed. Trafficcompaction is one of the main factors affecting crop productivity within Argentinean ...
Spatial variability of aquatic plant and microfaunal seed and egg bank communities within a forested floodplain system of a temperate Australian river
(2017-07-01)
Aquatic plant and microfaunal propagule banks represent a major source of regenerative potential in river-floodplain ecosystems. This study investigated the spatial patterns of microfaunal and aquatic plant propagule bank ...

(CT&F - Ciencia, Tecnología & FuturoColombia, 2020-12-17)
With the design of experiments (DoE), this study analyses the influence of physical (capillary diameter and pressure drop) and chemical variables (salinity, polymer concentration, and molecular weight) on the mechanical ...
CFD simulation of HPAM EOR solutions mechanical degradation by restrictions in turbulent flowSimulación CFD de la degradación mecánica por restricciones en flujo turbulento de soluciones HPAM EOR
(CT&F - Ciencia, Tecnología y FuturoColombia, 2020-12-17)
Polymer flooding is a widely used enhanced oil recovery (EOR) technology. The purpose of the polymer is to increase water viscosity to improve reservoir sweep efficiency. However, mechanical elements of the polymer injection ...
