💡 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).

Populations of Phytophthora infestans in northern and eastern Europe - European Journal of Plant Pathology

Phytophthora infestans (Mont.) de Bary is an oomycete plant pathogen that causes late blight in potato (Solanum tuberosum L.) and tomato (Solanum lycopersicum L.). This review documents the population structure of P. infestans in northern and eastern Europe, and aims to explain the differences between populations of P. infestans in this region and in western Europe. Populations of P. infestans are influenced by many factors, e.g., migrations related to the movement of potato seed tubers, possibility of sexual reproduction, changes in climate, and agricultural management practices. All the presented factors may have a significant impact on the P. infestans population structure. The knowledge on P. infestans populations varies strongly depending on country and time, even within the rather intensively studied region of eastern and northern Europe. Our review indicates some knowledge gaps, such as a lack of data for some countries and gaps in some years in population monitoring. This indicates the need to continue the monitoring of P. infestans populations.

🧪🍁 #Forest #Soils: How Harvesting Methods and Management Shape Soil Properties, Functions, and Resilience. Edited by Marian Schönauer and me at 🌲"Discover Forests". 🌳 APC currently waived, open till mid 2026 (tbd). link.springer.com/collections/... ... OA, reviews, welcome!

Article collection / special issue: Forest Soils: How Harvesting Methods and Management Shape Soil Properties, Functions, and Resilience

Journal: Discover Forests

Url: https://link.springer.com/collections/dgafjfgejh

Intensifying climate pressures and timber demands are refocusing attention on forest soils, the foundation of productivity, biodiversity, and ecosystem services. Harvesting methods can alter physical soil properties, hydrology, and nutrient cycles, while management incentives such as increased structural and species diversity, retention of deadwood and legacy trees, or the maintenance of refugia may buffer or reverse impacts.

Together, these practices govern soil carbon dynamics, greenhouse-gas fluxes, microbial and faunal communities, mycorrhizal networks, and erosion and water quality, yet the mechanistic links and context dependencies remain underexplored across forest types and pedoclimatic zones. This collection invites original research, perspectives and reviews that quantify how harvesting systems (e.g., reduced-impact logging, mechanized operations, continuous-cover forestry) and diversity/retention strategies (e.g., mixed-species stands, structural complexity, coarse woody debris) affect soil properties and functions.

We especially welcome studies that bridge scales, from plot to landscape and from short-term responses to long-term recovery, and that integrate physiology, biogeochemistry, soil ecology, and hydrology using field experiments, long-term trials, chrono sequences, remote sensing, geostatistical analysis, synthesis/meta-analysis, and/or innovative analytics (e.g., modelling, eDNA, isotopes). Submissions with regional to global scope and data-driven policy relevance (i.e., nature-based solutions) are encouraged.

Our goal is to draw attention to forest management practices that hinder or improve ecosystem functions and services by hampering or stewarding soil life and function.
