This study reports a bivalent factor, ULTRAPETALA1, that can counteract as well as promote PRC2 activity at hundreds of developmental genes in Arabidopsis thaliana. The pro-PRC2 activity of ULTRAPETAL...

Le Conseil européen de la recherche a annoncé ce jour la liste des lauréats des bourses ERC Advanced Grant, récompensant des scientifiques confirmés p

Comment les plantes libèrent-elles le contenu des vésicules autophagiques une fois celles-ci arrivées dans la vacuole ?

Climate warming poses increasing thermal challenges to plants, yet how plasma membrane biophysics contributes to heat adaptation remains poorly understood. In this work, we showed that the malectin-li...

Cytokinesis is a key process in the development of multicellular organisms, through both formative and proliferative divisions. In land plants, successful cytokinesis requires precise targeting of Gol...

Dr. Emmanuelle Bayer is a Principal Investigator, CNRS Research Director (class 1 since 2024, ranked 1st at the national level) at the Laboratory of Membrane

Serre et al. reveal that RALF peptides rapidly trigger PI4P-to-PI(4,5)P2 conversion at the plasma membrane downstream of the receptor kinase FERONIA. This acute phosphoinositide remodeling, mediated b...

Les plantes activent en quelques minutes des mécanismes de survie face aux stress environnementaux.

Colonization of plant roots by symbionts requires substantial morphodynamic reorganization. Examples are actin-scaffolded microcompartments called infection pockets formed during root nodule symbiosis...

Actin guides plant cell division, shaping tissues in ways that defy geometric constraints.

Les plasmodesmes, des canaux membranaires essentiels chez les plantes, jouent un rôle primordial dans la communication intercellulaire.

Membrane contact sites (MCSs) serve a critical role in intracellular communication, particularly between organelle membranes, enabling direct molecular transfer. Less clear is the role MCSs play in…

RHO OF PLANTS (ROPs) signaling and their activating factors ROPGEFs are essential for initiating polar growth, but which ones activate pollen germination is unknown. These authors show polarization of...

For the 20th time, participants of the Workshop on Plant Membrane Biology (WPMB) conference can learn about the latest findings in the crucial field of Plant Membrane Biology. Biological membranes ar…

When building an organ, adjacent cells coordinate to form topologically stable junctions by integrating mechanosensitive signaling pathways. Positioni…

Root expansion microscopy (ROOT-ExM) achieves super-resolution expansion microscopy in plants.

Membrane contact sites (MCSs) serve a critical role in intracellular communication, particularly between organelle membranes, enabling direct molecular transfer. Less clear is the role MCSs play in…
