Early Flowering 3 (ELF3) Inhibits Hypocotyl Phototropism in Light-Grown <i>Arabidopsis</i> Seedlings. [PDF]

Plant Direct
ABSTRACT Phototropic 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 high red:far‐red ratio (HRFR) and high levels of blue light (HBL). This occurs via activation

Water as a Compass: Hydrostimulation-Triggered Aerial Root Growth in Phalaenopsis aphrodite. [PDF]

Physiol Plant
ABSTRACT 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 ...

PINOID functions in root phototropism as a negative regulator [PDF]

Plant Signaling & Behavior, 2015
The PINOID (PID) family, which belongs to AGCVIII kinases, is known to be involved in the regulation of auxin efflux transporter PIN-formed (PIN) proteins through changes in the phosphorylation status. Recently, we demonstrated that the PID family is necessary for phytochrome-mediated phototropic enhancement in Arabidopsis hypocotyls and that the ...

Modelling torus behaviour in a fish farming cage

Aquaculture, Fish and Fisheries, 2022
Since it is not usually possible to observe all of the fish in a school, it is difficult to monitor farmed fish in a crowded cage with the aim of scrutinising their condition. One possible solution to this problem is the use of simulations.

Can Mimosa pudica Plants Enumerate Light Exposure Events? [PDF]

Cogn Sci
Abstract Plants sense and respond to information present in their surrounding environment. Recent work has sought to characterize the limits of these information processing abilities. Here, we present evidence that the movements of Mimosa pudica plants are mediated by the number of illumination events to which they have been exposed.

UV-B induced generation of reactive oxygen species promotes formation of BFA-induced compartments in cells of Arabidopsis root apices

Frontiers in Plant Science, 2016
UV-B radiation is an important part of the electromagnetic spectrum emitted by the sun. For much of the period of biological evolution organisms have been exposed to UV radiation, and have developed diverse mechanisms to cope with this potential stress ...

Positive/Negative Phototropism: Controllable Molecular Actuators with Different Bending Behavior [PDF]

, 2020
Herein, a series of molecular actuators based on the crystals of (E)‐2‐(4‐fluorostyryl)benzo[d]oxazole (BOAF4),(E)‐2‐(2,4‐difluorostyryl)benzo[d]oxazole (BOAF24), (E)‐2‐(4‐fluorostyryl)benzo[d]thiazole (BTAF4) and (E)‐2‐(2,4‐difluorostyryl)benzo[d]thiazole (BTAF24) showed unprecedented different bending behavior under UVirradiation.

Light as Stress Factor to Plant Roots – Case of Root Halotropism

Frontiers in Plant Science, 2014
Despite growing underground, largely in darkness, roots emerge to be very sensitive to light. Recently, several important papers have been published which reveal that plant roots not only express all known light receptors but also that their growth ...

High Pigment1 Mutation Negatively Regulates Phototropic Signal Transduction in Tomato Seedlings [PDF]

Plant Physiology, 2004
Abstract Phototropins and phytochromes are the major photosensory receptors in plants and they regulate distinct photomorphogenic responses. The molecular mechanisms underlying functional interactions of phototropins and phytochromes remain largely unclear.

Discussion on Photoreceptor for Negative Phototropism in Rice Roots

Rice Science, 2007
To properly explore the photoreceptor for the negative phototropism in rice (Oryza sativa L.) root, lights with different wavelengths were applied to investigate the effect of light quality on phototropic bending. The phototropic bending could be induced prominently by blue/ultraviolet light, whereas not by red or far-red light. The absorption spectrum
