Multiple light signaling pathways control solar tracking in sunflowers. [PDF]
PLoS Biology, 2023 Sunflowers are famous for their ability to track the sun throughout the day and then reorient at night to face east the following morning. This occurs by differential growth patterns, with the east sides of stems growing more during the day and the west ...

Early Flowering 3 (ELF3) Inhibits Hypocotyl Phototropism in Light‐Grown Arabidopsis Seedlings [PDF]
Plant DirectPhototropic bending of plants towards a light source allows them to position their photosynthetic tissues to optimize light capture. In light‐grown (de‐etiolated) Arabidopsis seedlings, phototropic bending of the hypocotyl is inhibited by light with a ...

Plant Signaling & Behavior, 2022 Climbing plants rely on suitable support to provide the light conditions they require in the canopy. Negative phototropism is a directional search behavior proposed to detect a support-tree, which indicates growth or movement away from light, based on ...

Air channels create a directional light signal to regulate hypocotyl phototropism
bioRxiv, 2023 In light-limiting conditions, aerial organs of most plants reorient their growth towards the light to improve photosynthesis, through a process known as phototropism1-3.

Diethyl ether anesthesia inhibits phototropic response in Arabidopsis thaliana by disrupting auxin redistribution [PDF]
Plant Signaling & BehaviorAlthough the term anesthesia is mainly associated with animals, it is well known that anesthetics also affect plants through their actions on membrane properties and protein function.

A phosphorylation switch turns a positive regulator of phototropism into an inhibitor of the process
Nature Communications, 2018 Light conditions modify plant growth and development via photoreceptors such as phototropins. Here the authors show that while phot1 promotes phototropism under low light, it can act to suppress phototropism in high-light environments through ...

Stem phototropism towards blue and ultraviolet light.
Physiologia Plantarum : An International Journal for Plant Biology, 2020 Positive phototropism is the process through which plants orient their organs towards a directional light source. While the blue light receptors phototropins (phot) play a major role in phototropism towards blue (B) and ultraviolet (UV) radiation, recent

Don’t be MIZguided, know where to grow! [PDF]
Communications BiologyPlant organs shift their directional growth in response to environmental stimuli through tropisms. Arabidopsis roots exhibit positive hydrotropism (towards water) and negative phototropism (away from light).
