Retrotransposon Evolution in Diverse Plant Genomes [PDF]
Genetics, 2000 Abstract Retrotransposon or retrotransposon-like sequences have been reported to be conserved components of cereal centromeres. Here we show that the published sequences are derived from a single conventional Ty3-gypsy family or a nonautonomous derivative.

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Higher order repeat structures reflect diverging evolutionary paths in maize centromeres and knobs
Genome BiologyBackground Highly repetitive tandem repeat arrays, known as satellite DNAs, are enriched in low-recombination regions such as centromeres. Satellite arrays often contain complex internal structures called higher-order repeats (HORs), which may have ...

Current and Forthcoming Approaches for Benchmarking Genetic and Genomic Diversity
Frontiers in Ecology and Evolution, 2021 The current attrition of biodiversity extends beyond loss of species and unique populations to steady loss of a vast genomic diversity that remains largely undescribed. Yet the accelerating development of new techniques allows us to survey entire genomes

Genomics and human diversity [PDF]
Cahiers de l’Urmis, 2021 The sequencing of the human genome (2003) has been followed by a number of technical developments that allow detailed characterization (including complete sequencing) of the DNA of thousands of individuals. This has provided an estimate of human genetic diversity: approx. 3 million base substitutions within our genome that includes 3,000 million bases.

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

The randomness that shapes our DNA
eLife, 2018 Just 5% of the human genome is subject to neutral evolution, but this process remains central to understanding the history of human migration across the Earth.

Evolutionary biology for the 21st century [PDF]
, 2013 New theoretical and conceptual frameworks are required for evolutionary biology to capitalize on the wealth of data now becoming available from the study of genomes, phenotypes, and organisms - including humans - in their natural environments.Molecular ...
