Negative Phototropism of Chlorophytum comosum Roots and Their Mechanisms

Horticultural Plant Journal, 2015
The aerial roots of Chlorophytum comosum were grown hydroponically, allowing us to study the performance and mechanism of negative phototropism. The results of this study were as follows.

Phototropism: Mechanism and Outcomes [PDF]

The Arabidopsis Book, 2010
Plants have evolved a wide variety of responses that allow them to adapt to the variable environmental conditions in which they find themselves growing. One such response is the phototropic response - the bending of a plant organ toward (stems and leaves) or away from (roots) a directional blue light source.

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.

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 ...

Planar polarity in primate cone photoreceptors: a potential role in Stiles Crawford effect phototropism

Communications Biology, 2022
Verschueren et al. expand our understanding of the Stiles-Crawford effect in mammals by using super-high resolution expansion microscopy of the adult macaque eye.

Nuclear phytochrome A signaling promotes phototropism in Arabidopsis [PDF]

, 2012
Phototropin photoreceptors (phot1 and phot2 in Arabidopsis thaliana) enable responses to directional light cues (e.g., positive phototropism in the hypocotyl).

Plant Phototropic Growth [PDF]

Current Biology, 2015
Plants are photoautotrophic sessile organisms that use environmental cues to optimize multiple facets of growth and development. A classic example is phototropism - in shoots this is typically positive, leading to growth towards the light, while roots frequently show negative phototropism triggering growth away from the light.

Comment on 'Lack of evidence for associative learning in pea plants'

eLife, 2020
In 2016 we reported evidence for associative learning in plants (Gagliano et al., 2016). In view of the far-reaching implications of this finding we welcome the attempt made by Markel to replicate our study (Markel, 2020).

phot1 inhibition of ABCB19 primes lateral auxin fluxes in the shoot apex required for phototropism [PDF]

, 2011
It is well accepted that lateral redistribution of the phytohormone auxin underlies the bending of plant organs towards light. In monocots, photoreception occurs at the shoot tip above the region of differential growth.
