Plant reproductive complexity increased in two, widely separated pulses likely driven by important evolutionary innovations, including the origin of seeds and flowers, according to a new study. These ...

In lab experiments and field studies, the team tracked the beetles with fluorescent dyes as they moved from cone to cone.

The exchange of ideas and information between vegetation ecology and pollination ecology is relatively restricted, yet both fields have devised methods to detect the structure of species assemblages ...

A gradient (red) in the concentration of auxin, a plant hormone, determines that only one of the eight undifferentiated nuclei in a plant's embryo sac will become an egg. (In this image, a large ...

Asteraceae presents one of the most diverse and intricate reproductive systems among flowering plants. The family is typified by its composite inflorescences, which combine both ray and disc florets ...

In plants, flowering is a crucial process for reproductive success and continuity of the species through time. Fruit production requires the perfect development of reproductive structures. Abscission, ...

We tend to think of plants as passive, vulnerable actors. But in their partnership with insects, it’s plants that often play ...

Some plants produce heat, which has long puzzled botanists. But a new study suggests that infrared radiation is an ancient ...

A gradient (red) in the concentration of the plant hormone auxin determines that only one of the eight nuclei in a plant's embryo sac will become an egg. (The blue island in the image is a cell ...

The sex organs of primitive plants are inspiring precise pipettes. Liverworts are a group of ground-hugging plants with male and female reproductive structures shaped like tiny palm trees. The female ...

While many modern plants use colorful flowers to attract pollinators, ancient palm-like plants called cycads lure them by ...
