Brachypodium distachyon (Poaceae) is now a widely accepted model grass. Its favourable cytogenetic features and advanced molecular infrastructure make it also a useful model system in

Umbellifers, a plant family that includes carrots, have striking inflorescences on stalks. Botanists have thought umbellifers have been generalists. They attract many different types of insect

Asexual reproduction via seeds (apomixis) is an important speciation mechanism in angiosperms, but its frequency is largely unknown. Mráz and Zdvořák used flow cytometric seed screening

Pierre-Oliver Cheptou examines two seemingly contradictory findings. Over the last 10 years, well-established patterns of evolution have emerged. First, experimental studies have shown that

Seed production of plants is rarely maximized, because it is limited by pollen receipt. Previous theories have shown that ecological mechanisms can drive the evolution of

If you share a pollinator with another plant species in your location, is it a good idea to flower at the same time? You can only

Scent matters. If you’re a flowering plant, scent is an important tool for attracting pollinators. It’s no surprise that botanists see it as a
