Fran @frangordilloc.bsky.social and I wrote this piece on one of our favorite topics: the evolutionary relevance of co-receptors for immune receptor transfer in #plants 🌱
#EvoMPMI #MPMI

Check also the beautiful paper by Zhang et al. on the PRR STOMR and discover what happened to its co-receptor 😱

Nataliia Rybchenko from @kwsgroup.bsky.social Ukraine presented her 'Sunflower' documentary at the #KWSScienceSlam.
Ukraine is the global leader in sunflower oil production, but amid the war, the sunflower has also become a symbol of freedom for Ukraine.

Documentary:
www.youtube.com/watch?v=2u2U...

Nataliia Rybchenko on stage presenting her documentary on Sunflower production in Ukraine. The slide behind her shows Sunflowers on the right, and text on the left. The text says: "The idea behind the film: The sunflower is more than a strategic crop, it's a symbol of resilience, heritage, and life - a land that keeps giving, even in dark times. Stories of science, business, culture, and emotion reveal its meaning. Our film's title, 'Sunflower: Meanings that seed the future', reflects this.

Nataliia Rybchenko on stage. The slide behind her shows a sunflower field and the the title 'Sunflower in Ukraine: A pillar crop amid challenges' Below are some facts: Sunflower is among Ukraine's top 3 profitable crops, Ukraine is global leader in sunflower oil production and exports, 27 % of the arable land is no longer available due to occupation, landmines, active war, 30 % of sowing area is at risk because of proximity to the active combat zones of the war.

🌽 Maize vs. Fusarium 🌽

Overexpressing a maize lipoxygenase (ZmLOX4) boosts resistance to Fusarium infection.

Glad that our maize Gene editing & transformation platform, at @rdplab.bsky.social, contributed to this research, led by the Lanubile's Lab.

💡 SPECIAL ISSUE VIEWPOINT 💡

Immune proteases are promising targets for protein engineering 🛠️ to boost disease resistance in plants 🌾 - Schuster et al.

🔗 doi.org/10.1093/jxb/...

#PlantScience 🧪 @marischuster.bsky.social @aciattoni.bsky.social

Fig. 1.Four classes of roles of immune proteases illustrated via examples. (i) Pathogen perception: Required for Cladosporium Resistance-3 (Rcr3) protease is inhibited by the fungal avirulence effector Avr2. The Rcr3-Avr2 complex is recognized by the immune receptor Cf-2, triggering a defence response (Kruger et al, 2002). (ii) Regulation of the immune response: METACASPASE 4 (MC4) is activated by calcium upon wounding or pathogen attack. MC4 cleaves tonoplast-located ProPEP1 releasing PEP1 to the apoplast where it is perceived by PEP RECEPTORS (PEPRs) thereby initiating defence responses (Hander et al, 2019). (iii) Counteracting pathogen effectors: soybean aspartic protease GmAP5, degrades the Phytophthora sojae virulence factor glycoside hydrolase family 12 (GH12) protein, XEG1 (Xia et al., 2020). (iv) Direct pathogen attack: secreted aspartic proteases (SAPs) cleave Pseudomonas syringae MucD protein thereby suppressing bacterial growth (Wang et al., 2019).
