Autor: Sarah Pamukcu, Aude Cerutti, Yann Bordat, Sonia Hem, Valérie Rofidal, Sébastien Besteiro

Publikováno v: PLoS Pathogens, Vol 17, Iss 11, p e1010096 (2021)

Iron-sulfur (Fe-S) clusters are one of the most ancient and ubiquitous prosthetic groups, and they are required by a variety of proteins involved in important metabolic processes. Apicomplexan parasites have inherited different plastidic and mitochon

Targeted Proteomics Allows Quantification of Ethylene Receptors and Reveals SlETR3 Accumulation in Never-Ripe Tomatoes

Autor: Yi Chen, Valérie Rofidal, Sonia Hem, Julie Gil, Joanna Nosarzewska, Nathalie Berger, Vincent Demolombe, Mondher Bouzayen, Beenish J. Azhar, Samina N. Shakeel, G. Eric Schaller, Brad M. Binder, Véronique Santoni, Christian Chervin

Publikováno v: Frontiers in Plant Science, Vol 10 (2019)

Ethylene regulates fruit ripening and several plant functions (germination, plant growth, plant-microbe interactions). Protein quantification of ethylene receptors (ETRs) is essential to study their functions, but is impaired by low resolution tools

The cell proliferation antigen Ki-67 organises heterochromatin

Publikováno v: eLife, Vol 5 (2016)

Antigen Ki-67 is a nuclear protein expressed in proliferating mammalian cells. It is widely used in cancer histopathology but its functions remain unclear. Here, we show that Ki-67 controls heterochromatin organisation. Altering Ki-67 expression leve

International audience; Iron (Fe) is a major micronutrient and is required for plant growth and development. Nongrass species have evolved a reduction-based strategy to solubilize and take up Fe. The secretion of Fe-mobilizing coumarins (e.g. fraxeti

Root membrane ubiquitinome under short-term osmotic stress

Publikováno v: International Journal of Molecular Sciences; Volume 23; Issue 4; Pages: 1956

Osmotic stress can be detrimental to plants, whose survival relies heavily on proteomic plasticity. Protein ubiquitination is a central post-translational modification in osmotic mediated stress. Plants use the ubiquitin (Ub) proteasome system to mod

Uptake of Fe-fraxetin complexes, an IRT1 independent strategy for iron acquisition in Arabidopsis thaliana

Autor: Joseph Chamieh, Max Stassen, Esther Izquierdo, Kevin Robe, Sonia Hem, Philippe Gonzalez, Christian Dubos, Véronique Santoni

SUMMARYIron (Fe) is a micronutrient essential for plant growth and development. Iron uptake in alkaline soil is a challenge for most plants. In this study, we investigated the role of the catechol coumarins fraxetin and esculetin in plant Fe acquisit

Besides the direct effects of radiations, indirect effects are observed within the surrounding non-irradiated area
irradiated cells relay stress signals in this close proximity, inducing the so-called radiation-induced bystander effect. These si

In contrast to desiccation-tolerant ‘orthodox’ seeds, so-called ‘intermediate’ seeds cannot survive complete drying and are short-lived. All species of the genus Coffea produce intermediate seeds, but they show a considerable variability in s
