Normally, animals get their DNA from their parents. But a new study shows that they can also get genes from another species. In fact, animals can even take genes from creatures outside of the animal ...

Biologists have made a detailed analysis of specific aspects of the genome of the important plant pest, the pea aphid. A special issue of Insect Molecular Biology reports the detailed analyses of ...

Pea aphids can free fall from the plants they feed on and -- within a fraction of a second -- land on their feet every time. Oftentimes, the falling aphids manage to cling to a lower part of the plant ...

The pea aphid is one of the weirdest and most versatile creatures around. It can reproduce sexually or asexually, can breed winged or unwinged babies, and is also a symbiote. This week, its genome has ...

Using an optimized CRISPR/Cas9 workflow and DIPA-CRISPR, researchers identified Laccase2 as essential for hardening and darkening overwintering eggs in pea aphids. Knockout mutations left eggs fragile ...

The first cutting of alfalfa is either done or underway in South Dakota, and we are starting to notice pea aphids in the fields. Although pea aphid populations can vary quite a bit from field to field ...

First it’s mammal bad breath. Then it’s babies pestering for piggyback rides. A near-death experience is tough on pea aphids. Now Gish and Moshe Inbar, both at the University of Haifa in Israel, ...

Induced prey defenses can be costly. These costs have the potential to reduce prey survival or reproduction and, therefore, prey population growth. I estimated the potential for predators to suppress ...

The pea aphid U-type symbiont (PAUS) was investigated to characterize its microbiological properties. Fluorescence in situ hybridization (FISH) and electron microscopy revealed that PAUS was a ...

There’s a reason your parents kept after you to eat your carrots. The vegetables (and lots of others, too) supply carotenoids, compounds that are good for vision and overall health. Animals, humans ...

Evolution is unfolding in real time within many natural animal populations and researchers are now observing how this influences biodiversity in the field. In a newly published study in Molecular ...
