DOI: 10.1007/978-1-4939-9015-3_2
Abstract: By the nineteenth century, root climbers and adhesive-tendril climbers were known to exhibit negative phototropism. Negative phototropism is shared by various plant species belonging to many taxonomic families and is considered to be an outcome… read more here.

DOI: 10.1007/s00344-017-9667-9
Abstract: Previous findings concerning two proteins involved in gravity and light-induced signal transduction, (AGD12-ADP-RIBOSYLATION FACTOR GTPase-ACTIVATING PROTEIN 12 and EHB1 (ENHANCED BENDING 1)), in Arabidopsis provided evidence for an antagonistic regulation of a gravitropic stimulus on… read more here.

DOI: 10.1007/s11515-018-1518-y
Abstract: BackgroundPhototropism is the response a plant exhibits when it is faced with a directional blue light stimulus. Though a seemingly simple differential cell elongation response within a responding tissue that results in organ curvature, phototropism… read more here.

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

DOI: 10.1093/jxb/erad015
Abstract: 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… read more here.

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

DOI: 10.1093/jxb/erad193
Abstract: 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. MIZU-KUSSEI1 (MIZ1) and GNOM/MIZ2… read more here.

Differential UVR8 Signal across the Stem Controls UV-B–Induced Inflorescence Phototropism
Sign Up to like & getrecommendations! Published in 2019 at "Plant Cell"
DOI: 10.1105/tpc.18.00929
Abstract: Unilateral UV-B exposure leads to differential UVR8 signal across Arabidopsis inflorescence stems, which is essential for UV-B–induced inflorescence phototropism. In the course of evolution, plants have developed mechanisms that orient their organs toward the incoming… read more here.
