Genes controlling mycorrhizal colonization discovered in soybean

Like most plants, soybeans pair up with soil fungi in a symbiotic mycorrhizal relationship. In exchange for a bit of sugar, the fungus acts as an extension of the root system to pull in more phosphorus, nitrogen, micronutrients, ...

Study tracks genomic changes that reinforce darter speciation

When they share habitat, orangethroat and rainbow darters tend to avoid one another, even though they are closely related and can produce "hybrid" offspring. The males compete with males of their own species and will almost ...

Researchers lay out first genetic history of Rome

Scholars have been studying Rome for hundreds of years, but it still holds some secrets—for instance, relatively little is known about the ancestral origins of the city's denizens. Now, an international team led by researchers ...

Marmoset monkeys can learn a new dialect

Monkeys and other animals communicate through calls that can differ depending on region. The common marmoset is one such animal that communicates using regional dialects. Researchers at the University of Zurich have now found ...
