Spatial IMA1 regulation restricts root iron acquisition on MAMP perception
Iron is critical during host–microorganism interactions1–4. Restriction of available iron by the host during infection is an important defence strategy, described as nutritional immunity5. However, this poses a c...

Plasmodesmata mediate cell-to-cell transport of brassinosteroid hormones
Brassinosteroids (BRs) are steroidal phytohormones that are essential for plant growth, development and adaptation to environmental stresses. BRs act in a dose-dependent manner and do not travel over long dist...

Open AccessThe receptor kinase SRF3 coordinates iron-level and flagellin dependent defense and growth responses in plants
Iron is critical for host–pathogen interactions. While pathogens seek to scavenge iron to spread, the host aims at decreasing iron availability to reduce pathogen virulence. Thus, iron sensing and homeostasis ...

Open AccessSphingolipids mediate polar sorting of PIN2 through phosphoinositide consumption at the trans-Golgi network
The lipid composition of organelles acts as a landmark to define membrane identity and specify subcellular function. Phosphoinositides are anionic lipids acting in protein sorting and trafficking at the trans-Gol...

Single-particle tracking photoactivated localization microscopy of membrane proteins in living plant tissues
Super-resolution microscopy techniques have pushed the limit of optical imaging to unprecedented spatial resolutions. However, one of the frontiers in nanoscopy is its application to intact living organisms. H...

Open AccessA phosphoinositide map at the shoot apical meristem in Arabidopsis thaliana
In plants, the shoot apical meristem (SAM) has two main functions, involving the production of all aerial organs on the one hand and self-maintenance on the other, allowing the production of organs during the ...

A PtdIns(4)P-driven electrostatic field controls cell membrane identity and signalling in plants
Many signalling proteins permanently or transiently localize to specific organelles. It is well established that certain lipids act as biochemical landmarks to specify compartment identity. However, they also ...

Guidelines for the Use of Protein Domains in Acidic Phospholipid Imaging
Acidic phospholipids are minor membrane lipids but critically important for signaling events. The main acidic phospholipids are phosphatidylinositol phosphates (PIPs also known as phosphoinositides), phosphati...
