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 ...

Phototropism: Translating light into directional growth [PDF]
American Journal of Botany, 2013 Phototropism allows plants to align their photosynthetic tissues with incoming light. The direction of incident light is sensed by the phototropin family of blue light photoreceptors (phot1 and phot2 in Arabidopsis), which are light‐activated protein kinases.

Deetiolation Enhances Phototropism by Modulating NON-PHOTOTROPIC HYPOCOTYL3 Phosphorylation Status [PDF]
Plant Physiology, 2019 Phototropin (phot) receptor kinases play important roles in promoting plant growth by controlling light-capturing processes, such as phototropism. Phototropism is mediated through the action of NON-PHOTOTROPIC HYPOCOTYL3 (NPH3), which is dephosphorylated following phot activation.

Flower movement induced by weather-dependent tropism satisfies attraction and protection. [PDF]
Nat CommunFlowers have antagonistic demands for reproductive success, that is, pollinator attraction and flower protection. However, how flowers accommodate these antagonistic reproductive demands has not been thoroughly analysed.

Shade Promotes Phototropism through Phytochrome B-Controlled Auxin Production [PDF]
, 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.

Light and gravity signals synergize in modulating plant development [PDF]
Frontiers in Plant Science, 2014 Tropisms are growth-mediated plant movements that help plants to respond to changes in environmental stimuli. The availability of water and light, as well as the presence of a constant gravity vector, are all environmental stimuli that plants sense and ...

Water as a Compass: Hydrostimulation-Triggered Aerial Root Growth in Phalaenopsis aphrodite. [PDF]
Physiol PlantABSTRACT Epiphytic orchids have evolved specialized adaptive strategies, such as aerial roots with water‐absorbing velamen tissues, to cope with water‐scarce and nutrient‐deficient habitats. Our previous study revealed that the aerial roots of the epiphytic orchid Phalaenopsis aphrodite lack a gravitropic response, raising the possibility that ...
