Local genetic adaption helps sorghum crop hide from witchweed

Sorghum crops in areas where the agricultural parasite striga, also known as witchweed, is common are more likely to have genetic adaptations to help them resist the parasite, according to new research led by Penn State scientists. ...

Scientists discover genomic key to plateau adaptation

Chinese scientists studying genomic data of hot-spring snakes have discovered the genetic mechanism for ectothermic animals' adaptation to extreme, high-elevation environments. The study, titled "Comparative genomic investigation ...

On the expansion threshold of a species' range

What stops a species adapting to an ever-wider range of conditions, continuously expanding its geographic range? The biomathematician Jitka Polechová, an Elise Richter Fellow at the University of Vienna, has published a ...

Genetic diversity helps protect against disease

So much for survival of the fittest – diversity is the key: a team of researchers from the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) has succeeded in demonstrating experimentally that genetic diversity ...
