Sphingolipid-driven interleaflet coupling orchestrates Rho-GTPase recruitment to nanodomains for signal activation in plants Open
Biological membranes are both laterally heterogeneous and asymmetrical across leaflets, yet how this asymmetry contributes to signal transduction remains unclear. Here we show that sphingolipid-driven interleaflet coupling coordinates nano…

Membrane nanodomains to shape plant cellular functions and signaling Open
Summary Plasma membrane (PM) nanodomains have emerged as pivotal elements in the regulation of plant cellular functions and signal transduction. These nanoscale membrane regions, enriched in specific lipids and proteins, behave as regulato…

The receptor kinase FERONIA regulates phosphatidylserine localization at the cell surface to modulate ROP signaling Open
Cells maintain a constant dialog between the extracellular matrix and their plasma membrane to fine tune signal transduction processes. We found that the receptor kinase FERONIA (FER), which is a proposed cell wall sensor, modulates phosph…

<i>Arabidopsis</i> vascular complexity and connectivity controls PIN-FORMED1 dynamics and lateral vein patterning during embryogenesis Open
Arabidopsis VASCULATURE COMPLEXITY AND CONNECTIVITY (VCC) is a plant-specific transmembrane protein that controls the development of veins in cotyledons. Here, we show that the expression and localization of the auxin efflux carrier PIN-FO…

Responses to Systemic Nitrogen Signaling in Arabidopsis Roots Involve <i>trans</i> -Zeatin in Shoots Open
Plants face temporal and spatial variation in nitrogen (N) availability. This includes heterogeneity in soil nitrate (NO3-) content. To overcome these constraints, plants modify their gene expression and physiological…

Root Responses to Heterogeneous Nitrate Availability are Mediated by <i>trans</i>-Zeatin in Arabidopsis Shoots Open
Plants are subjected to variable nitrogen (N) availability including frequent spatial nitrate (NO 3 - ) heterogeneity in soil. Thus, plants constantly adapt their genome expression and root physiology in order to optimize N acquisition fro…

Local signalling pathways regulate the Arabidopsis root developmental response to Mesorhizobium loti inoculation Open
Numerous reports have shown that various rhizobia can interact with non-host plant species, improving mineral nutrition and promoting plant growth. To further investigate the effects of such non-host interactions on root development and fu…

Long‐distance nitrate signaling displays cytokinin dependent and independent branches Open
Summary The long‐distance signaling network allowing a plant to properly develop its root system is crucial to optimize root foraging in areas where nutrients are available. Cytokinin is an essential element of the systemic signaling netwo…

The Nod factor-independent nodulation in Aeschynomene evenia required the common plant-microbe symbiotic "toolkit" Open
Nitrogen fixation in the legume-rhizobium symbiosis is a crucial area of research for more sustainable agriculture. Our knowledge of the plant cascade in response to the perception of bacterial Nod factors has increased in recent years. Ho…
