Sunflowers are famous for following the sun as it moves across the sky. So how do they do it? While previous work has proposed a mechanism for this movement, new work has suggested that the biological ...

A sunflower’s ability to track the sun east to west during the day, and to face east again before the next sunrise, relies on multiple types of photoresponses, according to a new study publishing ...

The way a young sunflower turns its bright yellow head to follow the movements of the Sun across the sky each day can be quite dramatic, in terms of plant activity. Now scientists have been surprised ...

Pass by a field of sunflowers at midsummer, and you'll notice every bright face turned toward the same patch of sky. Sunflowers track the sun from dawn until dusk, a graceful, slow-motion choreography ...

Sunflowers, true to their name, follow the sun with their bright yellow blooms. Their stems bend as they track the solar movement from east to west; then, when the sun sets, the flowers reorient ...

Sunflowers famously turn their faces to follow the sun as it crosses the sky. But how do sunflowers 'see' the sun to follow it? Plant biologists show that they use a different, novel mechanism from ...

Plant biologist Stacey Harmer studies how sunflowers are able to follow the sun. Her new research shows that sunflowers respond to the sun through a previously unknown mechanism. (Sasha Bakhter, UC ...

Sunflowers famously turn their faces to follow the sun as it crosses the sky. But how do sunflowers “see” the sun to follow it? New work from plant biologists at UC Davis, published Oct. 31 in PLOS ...
