Geological processes shaping freshwater biodiversity: a synthesis of global evidence
Biological Reviews, EarlyView.ABSTRACT Recent genomic data highlight the key roles of geological processes in shaping the diversification and biogeography of freshwater lineages. Specifically, physical processes such as tectonic uplift, erosion, glaciation, lake formation, and sea‐level fluctuation contribute extensively to the evolution of biotic diversity within and among ...

Animals, 2021 Although inter-species hybrids between the red and sika deer can be phenotypically determined only exceptionally, there is the eventuality of identification via molecular genetic analysis.

Introgression génique assistée par marqueurs [PDF]
INRAE Productions Animales, 1992 L’introgression génique consiste à inclure dans le génome d’une race sélectionnée A, un et un seul gène favorable, G, d’une race B par ailleurs moins productive. Ceci s’effectue classiquement par un premier croisement A×B, suivi d’une série de croisements en retour (Backcross), des descendants portant le gène G, par la race A. Tous ces descendants sont

International Journal of Cancer, EarlyView.What's New? Errors in DNA double‐strand break (DSB) repair can lead to mutations, chromosomal instability, and ultimately cancer. Inhibitor of DNA‐binding 3 (ID3), a transcriptional repressor, is crucial to promoting DSB repair and helping maintain genome stability. Here, the authors investigated ID3 regulation of DNA repair via chromatin accessibility

Electronic Journal of Plant Breeding, 2021 Diversity analysis of Bt lines, a prerequisite to heterosis breeding, are rarely published. Diversity analysis of 140 cotton genotypes comprising of BGI, BGII and Non-Bt lines resulted in the grouping of genotypes into 20 clusters among which five ...

Disentangling Immediate Adaptive Introgression from Selection on Standing Introgressed Variation in Humans [PDF]
Molecular Biology and Evolution, 2017 Recent studies have reported evidence suggesting that portions of contemporary human genomes introgressed from archaic hominin populations went to high frequencies due to positive selection. However, no study to date has specifically addressed the postintrogression population dynamics of these putative cases of adaptive introgression.

Molecular biology and evolution, 2019 Recent analyses suggest that cross-species gene flow or introgression is common in nature, especially during species divergences. Genomic sequence data can be used to infer introgression events and to estimate the timing and intensity of introgression ...

The Resurgence of Introgression Breeding, as Exemplified in Wheat Improvement
Frontiers in Plant Science, 2020 Breeding progress in most crops has relied heavily on the exploitation of variation within the species’ primary gene pool, a process which is destined to fail once the supply of novel variants has been exhausted.

A three-sample test for introgression [PDF]
Molecular Biology and Evolution, 2019 AbstractMany methods exist for detecting introgression between non-sister species, but the most commonly used require either a single sequence from four or more taxa or multiple sequences from each of three taxa. Here we present a test for introgression that uses only a single sequence from three taxa.

Defense heterosis as a novel plant protection strategy: From theory to breeding practice
New Plant Protection, EarlyView.Defense heterosis, the enhanced disease resistance of hybrids compared to their parents, has evolved from early observations of hybrid vigor to a novel research concept. Advances are now clarifying its diverse genetic and molecular mechanisms across various plant–pathogen interactions.
