💡 INSIGHT 💡

Vittoria Clapero comments on Liu et al.’s recent JXB paper - showing how ¹³C tracing reveals intra-leaf photosynthetic dynamics during drought & rewatering ☀️💧

Fig. 1.Effects of drought on plant metabolism and coping strategies. Drought is suggested to be first sensed in the roots and communicated to the rest of the plant via Ca2+, ROS, ABA, and small peptide signalling. Drought responses are manifold (left half); for example, plants can escape drought by increasing developmental speed in combination with early flowering, invest in their root system to maintain soil water uptake, synthesize compatible solutes to maintain the osmotic potential, and decrease their leaf transpiration by reducing stomatal conductance (reviewed in Farooq et al., 2009; Kuromori et al., 2022; Yang et al., 2021). Stomatal closure in turn starts a cascade of effects on metabolism (right half), causing reduced CO2 influx and ROS stress in the chloroplast, negatively affecting photosynthesis. Processes stimulated by drought are indicated with upwards arrows, and processes negatively affected by drought are indicated by downwards arrows. Figure created in BioRender

Resistance against bacterial wilt in tomato is linked to variety-specific proteomic changes; the CAPE1 peptide restricts Ralstonia solancearum growth in planta - Zhang et al. 🦠🍅

Fig. 3.PR1 protein features and alignment. (A) Representation of the tomato PR1 protein domains and conserved features. SP, signal peptide; CAP, cysteine-rich secretory proteins, antigen 5, and pathogenesis-related 1 protein domain, highlighting CAP3, CAP4, CAP1, CAP2, and CBM motifs; CAPE, CAP-derived peptide (Han et al., 2023). (B) Alignment of the representative PR1 proteins across different plant species. Amino acid alignment generated from ClustalO alignment of the representative PR1 proteins from tomato (Solanum lycopersicum), potato (Solanum tuberosum), pepper (Capsicum anuum), tobacco (Nicotiana tabacum), Arabidopsis (Arabidopsis thaliana), and wheat (Triticum aestivum). Red and blue highlighted regions show the last amino acid before the putative CAPE peptide cleavage. The conserved CAPE peptide sequence is shown in red.

📖 SPECIAL ISSUE REVIEW 📖

In this review, Wang et al. describe the protease, chaperone-like, and substrate processing working modes of plant FtsH, and summarize the role of FtsH in organelle protein homeostasis 🔄 🌱

#PlantScience 🧪

Box 1. Key developments in understanding FtsH functions for organelle protein homeostasis in Arabidopsis The schematic illustration shows the primary and 3D structure of FtsH (A–C) and highlights recent advances in understanding the roles of plant FtsHs localized in chloroplasts (D, E, and H) and mitochondria (F and G).

💡 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).
