Hydrogen peroxide mediates high-intensity blue light-induced hypocotyl phototropism of cotton seedlings. [PDF]

Stress Biol, 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 ...

14-3-3 proteins: Central hubs in plant development and stress adaptation. [PDF]

J Integr Plant Biol
This review highlights recent advances elucidating the important roles of 14‐3‐3 proteins in regulating phytohormone networks, biotic and abiotic stress tolerance, growth‐defense trade‐offs, and evolutionary adaptations. Furthermore, it provides a forward‐looking perspective on 14‐3‐3 biology and the development of climate‐resilient smart crops under ...

Negative phototropism is seen in Arabidopsis inflorescences when auxin signaling is reduced to a minimal level by an Aux/IAA dominant mutation, axr2. [PDF]

Plant Signal Behav, 2015
Inflorescences of a dominant mutant of Arabidopsis Aux/IAA7, axr2, showed negative phototropism with a similar fluence response curve to the positive phototropism of wild-type stems. Application of a synthetic auxin, NAA, and an inhibitor of polar auxin transport, NPA, increased and decreased respectively the magnitude of the phototropic response in ...

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.

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).

Phototropism in the Marine Red Macroalga Pyropia yezoensis [PDF]

, 2016
Phototropism is a response to the direction of light that guides growth orientation and determines the shape of plants to optimize photosynthetic activity. The phototropic response is present not only in terrestrial plants but also in water-living algae.

Phototropin phosphorylation of ROOT PHOTOTROPISM 2 and its role in mediating phototropism, leaf positioning and chloroplast accumulation movement in arabidopsis [PDF]

, 2023
Directional movements impact the ability of plants to respond and adjust their growth accordingly to the prevailing light environment. The plasma-membrane associated protein, ROOT PHOTOTROPISM 2 (RPT2) is a key signalling component involved in ...

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 ...

MIZU-KUSSEI1 (MIZ1) and GNOM/MIZ2 control not only positive hydrotropism but also phototropism in Arabidopsis roots

, 2023
In response to unilateral blue light illumination, roots of some plant species such as Arabidopsis thaliana exhibit negative phototropism (bending away from light), which is important for light avoidance in nature.
