📝 SPECIAL ISSUE REVIEW 📝

Hoernstein et al. consolidate information on Acylamino acid-releasing enzyme, a serine protease affecting plant development & aging, & emphasize its conserved features across all kingdoms of life 🌱🦠🧫

🔗 doi.org/10.1093/jxb/...

#PlantScience 🧪 @reskilab.bsky.social
Fig. 3 (shortened, full legend in paper): Summary of the current knowledge of acylamino acid-releasing enzyme (AARE) localization and function in plants and animals. AtAARE (green) is depicted as plant AARE and human AARE (blue) as animal AARE. Structures of both isoforms (AF-Q84LM4-F1, AF-P13798-F1; https://alphafold.ebi.ac.uk/) were predicted with AlphaFold (Jumper et al., 2021; Varadi et al., 2024). Middle shows commonalities between plants and animals: Localization of AARE to the nucleus and to the cytosol has been shown in Arabidopsis and human cell lines (Shimizu et al., 2003; Nakai et al., 2012; Zeng et al., 2017; Hoernstein et al., 2023). AARE functions as part of the antioxidant defence system in plants and animals (Shimizu et al., 2003; Nakai et al., 2012; Gogliettino et al., 2014; Riccio et al., 2015; Zeng et al., 2017). Left (only plants): AARE localizes to both plastids and mitochondria in plants (Hoernstein et al., 2023).

🔒🌿 SPECIAL ISSUE REVIEW 🔒🌿

Paiva-Silva et al. summarize and integrate current knowledge on protease inhibition in plant–pathogen interactions and speculate on ways in which this could be harnessed to improve plant resilience to biotic stresses 🦠💪

(A) Inhibition of endogenous plant proteases by plant protease inhibitors; (B) inhibition of pathogen/pest proteases by plant-derived protease inhibitors; (C) inhibition of plant proteases by pathogen-derived protease inhibitors. All proteases are denoted by the name of their homologue in Arabidopsis unless indicated otherwise. See paper for figure legend with abbreviations explanation.

💡 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).
