Photosensory adaptation mechanisms in hypocotyl phototropism: how plants recognize the direction of a light source

Journal of Experimental Botany, 2023
Plants recognize the light source direction and exhibit phototropic responses. Physiological studies have predicted that a difference in the light intensity received by the cells on the irradiated and shaded sides of a coleoptile/hypocotyl causes ...

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

Journal of Experimental Botany, 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.

Mutants of Arabidopsis thaliana with altered phototropism

Planta, 1989
Thirty five strains of Arabidopsis thaliana (L.) Heynh. have been identified with altered phototropic responses to 450-nm light. Four of these mutants have been more thoroughly characterized.

Phototropism: at the crossroads of light-signaling pathways

Trends in Plant Science, 2013
Phototropism enables plants to orient growth towards the direction of light and thereby maximizes photosynthesis in low-light environments. In angiosperms, blue-light photoreceptors called phototropins are primarily involved in sensing the direction of ...

Shoot phototropism in higher plants: New light through old concepts†

American Journal of Botany, 2013
Light is a key environmental factor that drives many aspects of plant growth and development. Phototropism, the reorientation of growth toward or away from light, represents one of these important adaptive processes.

Both phytochrome A and phytochrome B are required for the normal expression of phototropism in Arabidopsis thaliana seedlings

Physiologia Plantarum, 1997
The role of phytochrome A (phyA) and phytochrome B (phyB) in phototropism was investigated by using the phytochrome-deficient mutants phyA-101, phyB-1 and a phyA/phyB double mutant.

Light-dependent gravitropism and negative phototropism of inflorescence stems in a dominant Aux/IAA mutant of Arabidopsis thaliana, axr2 [PDF]

Journal of Plant Research, 2014
Gravitropism and phototropism of the primary inflorescence stems were examined in a dominant Aux/IAA mutant of Arabidopsis, axr2/iaa7, which did not display either tropism in hypocotyls.

Phototropin2-mediated hypocotyl phototropism is negatively regulated by JAC1 and RPT2 in Arabidopsis.

Plant physiology and biochemistry : PPB, 2021
Hypocotyl phototropism is redundantly mediated by phot1 and phot2, two blue light receptor phototropins, under the intensity of blue light>1 μmol m-2 s-1. As light intensity increases, phot1 inhibits the phot2-mediated response. To date, only Arabidopsis
