Phototropin responds to blue light and regulates starch storage by activating or deactivating PMSK1, a protein that controls starch synthesis. Blue light reduces starch accumulation, while red light ...

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 ...

Plants are experts at capturing solar energy, but their productivity can flag when light levels are low. New research may give them a boost when conditions get shady. Researchers were able to increase ...

Sophisticated control mechanisms optimize stomatal aperture and allow land plants to occupy habitats in ever changing environments 1,2. Stomatal aperture is regulated by light, water status, the ...

1) Phototropin receptors in the guard cells of stomata receives blue light; 2) Signal transmission by BLUS1, BHP and PP1 (proposed signaling components); 3) Activation of the plasma membrane proton ...

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 ...

High-starch algae are important in biofuel production, as a feed supplement in agriculture and as an efficient way to bind carbon dioxide. Researchers have now found a new method to control starch ...
