The DNA of life at its limits

Scientists have unraveled the complete genome of the tomato russet mite, which is considered one of the smallest animals on our planet and known as a destructive agricultural pest. The genome is the smallest reported to date ...

Scientists discover ancient enzymes evolve new tricks

Plants, herbivores, and pathogens are locked in a war for survival that is hundreds of millions of years old. Rooted in place and with no way to run, plants evolved complex, chemical-producing machinery in their cells to ...

Finding the missing step of an important molecular process

Lysine is an important amino acid that must be supplied in our diets, as our bodies can't produce lysine on their own. Most cereal grains have low levels of lysine, and scientists have worked to breed crops with higher lysine ...

Novel major locus regulates beak evolution of ground tit

Classical quantitative genetics has found that most phenotypes are polygenic traits. Under this polygenic model, natural selection often acts on many loci simultaneously, resulting in the combination of a few loci with major ...
