New tomato, potato family tree shows that fruit color and size evolved together

Fruits of Solanum plants, a group in the nightshade family, are incredibly diverse, ranging from sizable red tomatoes and purple eggplants to the poisonous green berries on potato plants. A new and improved family tree of this group, produced by an international team led by researchers at Penn State, helps explain the striking diversity of fruit colors and sizes and how they might have evolved.

Unexpected diversity of light-sensing proteins goes beyond vision in frogs

Frogs have maintained a surprising diversity of light-sensing proteins over evolutionary time, according to a new study led by a Penn State researcher. Light-sensing proteins, called opsins, enable vision in sighted animals, and are responsible for many more biological functions like regulating circadian rhythms. The researchers explored the evolution of nonvisual opsins in frogs, finding that most modern species examined in this study retained a shocking number of these proteins.
