In avocado and certain wild relatives in Lauraceae, a highly synchronized daily rhythm of floral sex timing promotes cross-pollination between two ...

STANFORD, CA—Calling it a “pretty slow one” as far as natural selection and genetic drift were concerned, biologists from Stanford University confirmed Tuesday that not much evolution happened today. ...

Large mobile genetic elements known as Starships act as vehicles for transferring transposable elements (TEs) between fungi. Here, Griem-Krey et al. show that these ‘hitchhiking’ TEs can drive rapid e...

The rice transcription factor genes NAC20 and NAC26 regulate grain filling and show allele-specific maternal expression due to transposable element insertions and paternal hypermethylation in their 5...

Evolutionarily related ‘proto-point’ centromeres providing resolution to the evolutionary origins of point centromeres are identified in yeast, and comparison shows they evolved in an ancestor with re...

Romeijn et al. reveal that horizontal transposon transfer is widespread in fungi, contributing up to 70% of transposon content in some taxa. The authors uncover thousands of events across diverse line...

The genome of Arabidopsis thaliana consists of 10 chromosomes. By inducing CRISPR-Cas–mediated breaks at subcentromeric and subtelomeric sequences, we fused entire chromosome arms, obtaining two eight...

Understanding how life is adapting to urban environments represents an important challenge in evolutionary biology. In this work, we investigate a widely cited example of urban adaptation, Culex pipie...

Viruses rely on host cell translational machinery to produce viral proteins necessary for their propagation. Therefore, from the hosts point of view, ribosomes are at the forefront to invading viruses. Given the distant evolutionary divergence, viral sequences are not as...

Cells require highly polymorphic receptors to perform accurate self/non-self recognition. In the amoeba Dicytostelium discoideum, polymorphic TgrB1 & TgrC1 proteins are used to bind sister cells and e...

Chromosomal inversions can contribute to adaptive speciation by linking coadapted alleles. By querying 1375 genomes of the species-rich Malawi cichlid fish radiation, we discovered five large inversio...

Characterization of the genetic architecture underlying the 7 pairs of contrasting traits studied by Mendel and the over 70 additional agronomic traits in pea (Pisum sativum) reveals their m...

Abstract. Transposable elements are repetitive DNA sequences that excise or create copies that are inserted elsewhere in the genome. Their expansion shapes

Transposable elements (TEs) constitute a major portion of plant genomes and play key roles in shaping genome architecture, regulating gene expression, and driving genome evolution. In this study, we g...

Nature Ecology & Evolution - Multi-omics analysis reveals that a 254-bp transposon induces defensive camouflage in an alpine plant and reduces herbivory by caterpillars of a specialist...

In the Multicellularity Long Term Evolution Experiment, diploid yeast evolve to be tetraploid under selection for larger multicellular size, revealing how whole-genome duplication can arise due to its...

Tn7 family transposons are mobile genetic elements known for precise target site selection, with some co-opting CRISPR-Cas systems for RNA-guided transposition. We identified a novel group of Tn7-like...

Plants must carefully time their life cycle events, such as germination and flowering, to their environment. But with changing...

Cultivated raspberries (Rubus idaeus L.) most commonly bear small, red, highly aromatic fruits. Their colour is derived predominantly from anthocyanins, water soluble polyphenolic pigments, but as wel...

Single-cell measurement of the Huntington’s disease-causing CAG repeat reveals that somatic expansion of this repeat drives pathological changes in neurons, providing insights into disease progression...

Horizontal transfer of genetic material in eukaryotes has rarely been documented over short evolutionary timescales. Here, the authors show that two transposable elements, Shellder and Spoink, invaded...

Abstract. Transposable elements (TEs) comprise a major fraction of vertebrate genomes, yet little is known about their expression and regulation across tis

Epigenetic inheritance can be influenced by environmental conditions and somatic inputs originating from different tissues. Such transgenerational inheritance is reversable as it does not lead to muta...
