Dannay M, Bertin C, Cavallari E, Albanese P, Tolleter D, Giustini C, et al.
Proc Natl Acad Sci U S A
. 2025 Feb;
122(7):e2418687122.
PMID: 39946539
Photosynthesis, the fundamental process using light energy to convert carbon dioxide to organic matter, is vital for life on Earth. It relies on capturing light through light-harvesting complexes (LHC) in...

Leonardelli M, Tissot N, Podolec R, Ares-Orpel F, Glauser G, Ulm R, et al.
Plant Physiol
. 2024 Jun;
196(2):1518-1533.
PMID: 38918833
Plants must balance light capture for photosynthesis with protection from potentially harmful ultraviolet (UV) radiation. Photoprotection is mediated by concerted action of photoreceptors, but the underlying molecular mechanisms are not...

Chen S, Podolec R, Arongaus A, Fuchs C, Loubery S, Demarsy E, et al.
Plant Physiol
. 2023 Nov;
194(3):1563-1576.
PMID: 37956407
Photoperiodic plants coordinate the timing of flowering with seasonal light cues, thereby optimizing their sexual reproductive success. The WD40-repeat protein REPRESSOR OF UV-B PHOTOMORPHOGENESIS 2 (RUP2) functions as a potent...

Stockenhuber R, Akiyama R, Tissot N, Milosavljevic S, Yamazaki M, Wyler M, et al.
Plant Cell Physiol
. 2023 Sep;
65(1):35-48.
PMID: 37757822
As sessile, photoautotrophic organisms, plants are subjected to fluctuating sunlight that includes potentially detrimental ultraviolet-B (UV-B) radiation. Experiments under controlled conditions have shown that the UV-B photoreceptor UV RESISTANCE LOCUS...

Fang F, Lin L, Zhang Q, Lu M, Skvortsova M, Podolec R, et al.
New Phytol
. 2022 Sep;
236(5):1824-1837.
PMID: 36089828
Light regulates the subcellular localization of plant photoreceptors, a key step in light signaling. Ultraviolet-B radiation (UV-B) induces the plant photoreceptor UV RESISTANCE LOCUS 8 (UVR8) nuclear accumulation, where it...

Podolec R, Wagnon T, Leonardelli M, Johansson H, Ulm R
Plant J
. 2022 May;
111(2):422-439.
PMID: 35555928
Plants undergo photomorphogenic development in the presence of light. Photomorphogenesis is repressed by the E3 ubiquitin ligase CONSTITUTIVELY PHOTOMORPHOGENIC 1 (COP1), which binds to substrates through their valine-proline (VP) motifs....

Ayatollahi Z, Kazanaviciute V, Shubchynskyy V, Kvederaviciute K, Schwanninger M, Rozhon W, et al.
J Exp Bot
. 2022 Jan;
73(8):2369-2384.
PMID: 35088853
Mitogen-activated protein kinase (MAPK) cascades transmit environmental signals and induce stress and defence responses in plants. These signalling cascades are negatively controlled by specific Ser/Thr protein phosphatases of the type...

Podolec R, Demarsy E, Ulm R
Annu Rev Plant Biol
. 2021 Feb;
72:793-822.
PMID: 33636992
Ultraviolet-B (UV-B) radiation is an intrinsic fraction of sunlight that plants perceive through the UVR8 photoreceptor. UVR8 is a homodimer in its ground state that monomerizes upon UV-B photon absorption...

Podolec R, Lau K, Wagnon T, Hothorn M, Ulm R
Proc Natl Acad Sci U S A
. 2021 Feb;
118(6).
PMID: 33542100
The plant ultraviolet-B (UV-B) photoreceptor UVR8 plays an important role in UV-B acclimation and survival. UV-B absorption by homodimeric UVR8 induces its monomerization and interaction with the E3 ubiquitin ligase...

PLoS Genet
. 2020 May;
16(5):e1008797.
PMID: 32392219
Sun-loving plants perceive the proximity of potential light-competing neighboring plants as a reduction in the red:far-red ratio (R:FR), which elicits a suite of responses called the "shade avoidance syndrome" (SAS)....
