Complexity of the 5′ Untranslated Region of EIF4A3, a Critical Factor for Craniofacial and Neural Development

Frontiers in Genetics, 2018
Repeats in coding and non-coding regions have increasingly been associated with many human genetic disorders, such as Richieri-Costa-Pereira syndrome (RCPS).

Linkage variation and chromosome maps [PDF]

, 1921
A recent paper in this journal by Detlefsen(1) is introduced as follows: "There is a well intrenched concept of recent genetics that hereditary factors or genes may be given fairly definite loci on chromosome maps and that these maps correspond to or ...

Genetic variability in soybean with resistance to cyst nematode and powdery mildew: impact of multi-parent crosses on recombination and genetic diversity [PDF]

Brazilian Journal of Biology
The objective of this study was to analyze the genetic variability generated from two-way, four-way, and eight-way hybridizations in soybean, derived from parental lines contrasting in resistance to cyst nematode and powdery mildew.

The dmc1 Mutant Allows an Insight Into the DNA Double-Strand Break Repair During Meiosis in Barley (Hordeum vulgare L.)

Frontiers in Plant Science, 2019
Meiosis is a process of essential importance for sexual reproduction, as it leads to production of gametes. The recombination event (crossing-over) generates genetic variation by introducing new combination of alleles.

The role of environmental, structural and anthropogenic variables on underpass use by African savanna elephants (Loxodonta africana) in the Tsavo Conservation Area

Global Ecology and Conservation, 2022
Wildlife crossing structures are effective interventions for mitigating fragmentation of habitats by linear infrastructure. The 2017 construction of a new railway cutting through the Tsavo Conservation Area (TCA), home to the largest elephant population ...

Investigation of Wildlife Crossing Structures in South Korea [PDF]

Geo Data, 2023
Roads, railways and infrastructure are constructed with consideration of their environmental impacts, especially habitat fragmentation. Wildlife crossing structures increase the permeability of roads and other linear infrastructures for wildlife by ...

Crossing over with the Angel

Sign Systems Studies, 2005
This essay is an analytical extension of Roland Barthes’ structural analysis of an excerpt from the Old Testament (Genesis 32: 22–32), known as “The Struggle with the Angel”. It thus continues the search for “the third meaning” of this enigmatic passage.

Vortex Molecules in Spinor Condensates [PDF]

, 2008
Condensates of atoms with spins can have vortices of several types; these are related to the symmetry group of the atoms' ground state. We discuss how, when a condensate is placed in a small magnetic field that breaks the spin symmetry, these vortices ...

Comparative gene mapping in Arabidopsis lyrata chromosomes 1 and 2 and the corresponding A. thaliana chromosome 1: recombination rates, rearrangements and centromere location [PDF]

, 2006
To add detail to the genetic map of Arabidopsis lyrata, and compare it with that of A. thaliana, we have developed many additional markers in the A. lyrata linkage groups, LG1 and LG2, corresponding to A. thaliana chromosome 1.
