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). Changes in R:FR are primarily

A phosphorylation switch turns a positive regulator of phototropism into an inhibitor of the process

Autor: Paolo Schumacher, Emilie Demarsy, Patrice Waridel, Laure Allenbach Petrolati, Martine Trevisan, Christian Fankhauser

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-9 (2018)
Nature communications, vol. 9, no. 1, pp. 2403

Phototropins are light-activated protein kinases, which contribute to photosynthesis optimization both through enhancement of photon absorption when light is limiting and avoidance responses in high light. This duality is in part endowed by the prese

The Molecular and Physiological Responses of Physcomitrella patens to Ultraviolet-B Radiation

Autor: Luise Wolf, Roman Ulm, Luca Rizzini, Stefan A. Rensing, Ralf Stracke

Publikováno v: Plant Physiology, Vol. 153, No 3 (2010) pp. 1123-1134

Ultraviolet-B (UV-B) radiation present in sunlight is an important trigger of photomorphogenic acclimation and stress responses in sessile land plants. Although numerous moss species grow in unshaded habitats, our understanding of their UV-B response

CONSTITUTIVELY PHOTOMORPHOGENIC1 Is Required for the UV-B Response in Arabidopsis

Autor: Agnieszka Brzezinska, Roman Ulm, Zoltán Máté, Jean Molinier, Ferenc Nagy, Edward J. Oakeley, Alexander Baumann, Attila Oravecz, Eberhard Schäfer, Éva Ádám

Publikováno v: Plant Cell, Vol. 18, No 8 (2006) pp. 1975-1990

CONSTITUTIVELY PHOTOMORPHOGENIC1 (COP1) is a negative regulator of photomorphogenesis in Arabidopsis thaliana. COP1 functions as an E3 ubiquitin ligase, targeting select proteins for proteasomal degradation in plants as well as in mammals. Among its

Genome-wide analysis of gene expression reveals function of the bZIP transcription factor HY5 in the UV-B response of Arabidopsis

Autor: Eberhard Schäfer, Attila Oravecz, Alexander Baumann, Ferenc Nagy, Edward J. Oakeley, Roman Ulm, Zoltán Máté, Éva Ádám

Publikováno v: Proceedings of the National Academy of Sciences, Vol. 101, No 5 (2004) pp. 1397-1402

The light environment is a key factor that governs a multitude of developmental processes during the entire life cycle of plants. An important and increasing part of the incident sunlight encompasses a segment of the UV-B region (280–320 nm) that i

Auxin-mediated plant architectural changes in response to shade and high temperature

Autor: Christian Fankhauser, Séverine Lorrain, Mieke de Wit

Publikováno v: Physiol Plantarum

The remarkable plasticity of their architecture allows plants to adjust growth to the environment and to overcome adverse conditions. Two examples of environmental stresses that drastically affect shoot development are imminent shade and high tempera

Conditional Involvement of CONSTITUTIVE PHOTOMORPHOGENIC1 in the Degradation of Phytochrome A

Autor: Martine Trevisan, Dimitry Debrieux, Christian Fankhauser

Plant Physiology

All higher plants possess multiple phytochrome photoreceptors, with phytochrome A (phyA) being light labile and other members of the family being relatively light stable (phyB–phyE in Arabidopsis [Arabidopsis thaliana]). phyA also differs from othe

Functional interaction of the circadian clock and UV RESISTANCE LOCUS 8-controlled UV-B signaling pathways in Arabidopsis thaliana

Autor: Fehér, Balázs, Kozma-Bognár, László, Kevei, Eva, Hajdu, Anita, Binkert, Melanie, Davis, Seth Jon, Schäfer, Eberhard, Ulm, Roman, Nagy, Ferenc

Publikováno v: The Plant Journal, Vol. 67, No 1 (2011) pp. 37-48

Circadian clocks regulate many molecular and physiological processes in Arabidopsis (Arabidopsis thaliana), allowing the timing of these processes to occur at the most appropriate time of the day in a 24-h period. The accuracy of timing relies on the

Negative feedback regulation of UV-B–induced photomorphogenesis and stress acclimation in Arabidopsis

Publikováno v: Proceedings of the National Academy of Sciences, Vol. 107, No 46 (2010) pp. 20132-20137

Plants respond to low levels of UV-B radiation with a coordinated photomorphogenic response that allows acclimation to this environmental stress factor. The key players in this UV-B response are COP1 (an E3 ubiquitin ligase), UVR8 (a β-propeller pro

ATAB2 is a novel factor in the signalling pathway of light-controlled synthesis of photosystem proteins

Autor: Jean-David Rochaix, Veronika Winter, Fredy Barneche, Michèle Crèvecœur

Publikováno v: EMBO Journal, Vol. 25, No 24 (2006) pp. 5907-18

Plastid translational control depends to a large extent on the light conditions, and is presumably mediated by nucleus-encoded proteins acting on organelle gene expression. However, the molecular mechanisms of light signalling involved in translation
