Scientists crack the code to improve stress tolerance in plants

In any eukaryotic organism, the DNA in a cell exists not as a loose strand, but as a highly condensed complex that consists of DNA and other proteins known as histones. Overall, this condensed structure is referred to as ...

Researchers identify how eye loss occurs in blind cavefish

Loss of eye tissue in blind cavefish (Astyanax mexicanus), which occurs within a few days of their development, happens through epigenetic silencing of eye-related genes, according to a study led by the National Institutes ...

Decoding behavioral variation in ant clones

Genetically identical clonal ants show surprising diversity in their attraction to sweetness, according to new research in the journal Royal Society Open Science. While differences in behavior and preferences among a species ...

Dieting causes epigenetic changes during ageing

Reduced food consumption extends the lifespan of many organisms, including primates. The biology behind how this is achieved, however, is not yet fully understood. Researchers at the Max Planck Institute for Biology of Ageing ...

DNA methylation affects superiority of hybrid plants

Hybrid vigor refers to when a crossbreed plant or animal shows superior traits compared to its parents. A research group has discovered that a gene involved in maintaining DNA methylation is closely connected to hybrid vigor ...

New insights into cooperativity in gene regulation

In a study published in Nature, Dirk Schübeler and his group at the Friedrich Miescher Institute for Biomedical Research (FMI) describe how the interplay between transcription factors and epigenetic modifications of DNA ...

What gave us the advantage over extinct types of humans?

In parallel with modern man (Homo sapiens), there were other, extinct types of humans with whom we lived side by side, such as Neanderthals and the recently discovered Denisovans of Siberia. Yet only Homo sapiens survived. ...
