Plasmodesmata act as unconventional membrane contact sites regulating inter-cellular molecular exchange in plants

The paper shows plasmodesmata function as ER-PM tubular membrane contact sites that regulate intercellular molecular exchange in plants through PI4P and MCTP proteins.

The AFB1 auxin receptor controls the cytoplasmic auxin response pathway in Arabidopsis thaliana

This study identifies the N-terminal region of AFB1 as critical for its specific role in the rapid auxin response pathway in Arabidopsis thaliana, including calcium influx and root growth inhibition.

Root Walker: an automated pipeline for large scale quantification of early root growth responses at high spatial and temporal resolution

Root Walker quantifies root growth responses to environmental signals using automated imaging and analysis, revealing auxin concentration dependence and MAPK inhibitor specificity.

Ubiquitination steers SRF3 plasma membrane nano-organization to specify signaling outputs

The paper shows that ubiquitination of SRF3 organizes its plasma membrane nano-organization, directing signaling outputs based on environmental cues like low iron or bacterial signals.

The receptor kinase SRF3 coordinates iron-level and flagellin dependent defense and growth responses in plants

This study identifies SRF3 as a receptor kinase that coordinates iron homeostasis and immune responses in plants by regulating callose synthase activity.

A plasma membrane nanoplatform ensures signal specificity during osmotic signaling in plants

The paper shows that Rho GTPase nanodomains at the plasma membrane ensure signal specificity during osmotic signaling in plants by transducing reactive oxygen species production.

Sphingolipids mediate polar sorting of PIN2 through phosphoinositide consumption at the trans-Golgi Network

The paper shows that sphingolipids regulate phosphoinositide levels at the TGN by mediating PI4P consumption via PI-PLC, affecting PIN2 sorting.

Shoot and root thermomorphogenesis are linked by a developmental trade-off

The paper shows that shoot and root growth responses to high temperature are coordinated during early seedling development through shared signaling modules and auxin regulation.

In vivo phosphatidylserine variations steer Rho GTPase signaling in a cell-context dependent manner

The paper shows phosphatidylserine regulates Rho GTPase signaling in Arabidopsis by modulating ROP6 nanoclusters and auxin signaling during root development.

A combinatorial lipid code shapes the electrostatic landscape of plant endomembranes

The paper identifies specific lipids that control membrane electrostatics in plant cells and shows how their combination creates distinct electrostatic territories along the endocytic pathway.
