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 ...

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 ...

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 ...

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 ...
