Hydrogen peroxide mediates high-intensity blue light-induced hypocotyl phototropism of cotton seedlings [PDF]
Stress Biology, 2023 Phototropism is a classic adaptive growth response that helps plants to enhance light capture for photosynthesis. It was shown that hydrogen peroxide (H2O2) participates in the regulation of blue light-induced hypocotyl phototropism; however, the ...

Shade Promotes Phototropism through Phytochrome B-Controlled Auxin Production [PDF]
Current Biology, 2016 Phototropism is an asymmetric growth response enabling plants to optimally position their organs. In flowering plants, the phototropin (phot) blue light receptors are essential to detect light gradients.

Phytochrome A Mediates Blue-light Enhancement of Second-positive Phototropism in Arabidopsis [PDF]
Frontiers in Plant Science, 2016 Hypocotyl phototropism of etiolated Arabidopsis seedlings is primarily mediated by the blue-light receptor kinase phototropin 1 (phot1). Phot1-mediated curvature to continuous unilateral blue light irradiation (0.5 µmol m-2 s-1) is enhanced by overhead ...

Cell Reports, 2020 Summary: The asymmetric distribution of auxin leads to the bending growth of hypocotyls during gravitropic and phototropic responses, but the signaling events downstream of auxin remain unclear.

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 ...

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).

Tropic responses of potato single-node explant cultures [PDF]
Archives of Biological Sciences, 2012 A special in-vitro protocol was elaborated enabling the production of potato single-node explant plantlets that can be used as objects for tropic studies.
