Cell-specialized chloroplast signaling orchestrates photosynthetic and extracellular reactive oxygen species for stress responses

This study identifies how chloroplast retrograde signals like PAP coordinate ROS production in guard cells to regulate stomatal closure during stress.

Arabidopsis Poly(ADP-ribose)-binding protein RCD1 interacts with Photoregulatory Protein Kinases in nuclear bodies

This paper identifies RCD1 as a PAR-binding protein that localizes to nuclear bodies and interacts with PPKs, which phosphorylate RCD1 and regulate its stability and function.

CRK2 and C-terminal phosphorylation of NADPH oxidase RBOHD regulate ROS production in Arabidopsis

This study identifies CRK2 as a regulator of RBOHD-mediated ROS production in Arabidopsis, showing that CRK2 phosphorylates RBOHD's C-terminus to enhance defense against pathogens.

Golgi anti-apoptotic proteins are evolutionarily conserved ion channels that regulate cell death in plants

This study identifies plant GAAPs as Golgi-localized ion channels that regulate cell death by modulating ionic homeostasis, showing functional conservation with human and viral GAAPs.

CRK2 enhances salt tolerance by regulating callose deposition in connection with PLDα1

The paper shows CRK2 enhances salt tolerance in Arabidopsis by regulating endocytosis and callose deposition, working with PLDα1.

Mechanistic insights into the evolution of DUF26-containing proteins in land plants

The paper traces the evolutionary history of DUF26-containing proteins in land plants, showing their origin from secreted proteins and expansion through duplication mechanisms.

An Oomycete Effector Protein Induces Shade Avoidance In Arabidopsis And Attenuates Salicylate Signaling By Binding To Host Proteins Of The RADICAL-INDUCED CELL DEATH1 Family

The paper shows that the oomycete effector HaRxL106 induces shade avoidance and suppresses salicylic acid signaling in Arabidopsis by interacting with RCD1, a protein involved in immune responses.
