🚨 A new twist in #NLRbiology! 🚨

Excited to report on the surprising mechanism where the helper NLR NRG1 targets organellar membranes to trigger immunity unlike canonical CC-NLRs, which function at the plasma membrane!

Blue light decreases ER Ca²⁺ in stomatal guard cells, with refilling in the dark. Our new @NewPhyt study shows how ER Ca²⁺ shapes cytosolic Ca²⁺ dynamics

How plants sense injury in their barrier tissue, periderm? Painstakingly detailed and amazing work by post doc Hiroyuki Iida shows that wounding is sensed by the diffusion of two gases: ethylene and oxygen. https://t.co/zb5iQ05qcx

Thank you for the mention, Maddy Seale @ScienceMagazine. Here are additional images of light focused by water droplets, captured by Jenny Svennås-Gillner @_SLU.

Here, we dissect the processing and release mechanism of the maize phytocytokine Zip1. Our results reveal a two-step mechanism of phytocytokine processing, translocation, activation and clearance. Ty @gun_doe @SimonStael @JohanaMisas and everyone involded

We found that high light can trigger calcium responses in the chloroplast stroma, cytosol and ER, dependent on photoinhibition, ROS formation, and temperature, revealing an unexpected connection between ER and stromal calcium pools!

What started as a 'funky' observation back in 2017 while visiting the lab of @lab_costa and after skilfull execution of @DominicKwong11, @RomandShanna, and many more, now found a home in Current Biology. https://t.co/ar6miLtPwS
