Sequencing the gardenia genome shows how plants evolved to re-use tricks from their genetic toolbox to create new chemicals.

When pollen resources are low, bumblebees damage plants to help drive more flowering so they can get more, researchers have found.

A wild dandelion's spiny pollen has evolved to attach to traveling bumblebees, report researchers.
