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.

Why is breaking down plant material for biofuels so slow?

Breaking down cellulose for biofuel is slow and inefficient but could avoid concerns around using a food source while taking advantage of abundant plant materials that might otherwise go to waste. New research led by Penn State investigators has revealed how several molecular roadblocks slow this process.
