A new study presents an evolutionary-biophysical model that sheds new light on the evolution of the collaborative non-self recognition self-incompatibility, a genetic mechanism in plants that prevents ...

Molecular evolution examines how DNA, RNA and protein sequences change over time under the influence of mutation, selection, drift and recombination. Variation arises through replication errors and ...

An international team of researchers has uncovered a remarkable genetic phenomenon in lycophytes, which are similar to ferns and among the oldest land plants. Their study reveals that these plants ...

Justin Havird, Erik Iverson and their colleagues have identified genes involved in hybrid incompatibility in swordtail fishes. The sheepshead swordtail fish (Xiphophorus birchmanni). Photo credit: Dan ...

Plants, with their unique immune systems, sometimes launch 'autoimmune responses' by mistakenly identifying their own protein structures as pathogens. In particular, 'hybrid necrosis,' a phenomenon ...

New research suggests a genetic dynamic that may have contributed to Neanderthals' extinction. Neanderthal-Museum, Mettmann CC BY-SA 4.0 via Wikimedia Commons Did interbreeding between humans and ...

Previous models of self-incompatibility accounted for only one-to-one interactions between male and female-determinant proteins. The new model allows for a more general network of interactions, where ...
