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.

Nature - A study using Arabidopsis shows that plants can monitor the integrity of their outer barriers by sensing gas diffusion, enabling them to initiate wound repair to prevent water loss and...

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.

Excellent work from the lab by @DominicKwong11 and @RomandShanna !
💦 Waterdrops induce burning glass effect on leaves 🍃🌿 Check how does it influence photosynthesis and Ca²⁺ dynamics in our recent work on bioRxiv ;) @SimonStael @RomandShanna @SpeteaCornelia @lab_costa @schwarzland_lab @DanielVanDamme1

Curious about how high light affects chloroplast and ER Ca²⁺ dynamics in plants? @schwarzland_lab @DanielVanDamme1 @lab_costa @SimonStael

Outraged that Sweden forces infants BORN IN SWEDEN on a long journey *out of the country* just to apply for residence permits. A giant F-U to foreign researchers and pointless risks for my daughter. @Migrationsverk @_SLU @KAWstiftelsen @usembsweden
