Summary: This study reveals an increase in pathotype diversity of Phytophthora sojae isolates and a decrease in the efficacy of specific Rps genes used for disease management. The widely deployed Rps1a, Rps1c, and Rps1k genes in the United States, Argentina, and Canada are no longer effective, highlighting the need for new sources of resistance to effectively manage Phytophthora stem and root rot.

Summary: Phytophthora root rot in soybeans, caused by Phytophthora sojae (P. sojae), significantly reduces soybean production. This study analyzed miRNAs that respond to P. sojae from a gene level perspective to understand molecular resistance mechanisms in soybean. High-throughput sequencing of soybean data was used to predict and analyze P. sojae-responsive miRNAs, and their regulatory relationships were verified through qRT-PCR. The study found that miRNAs in soybean respond to P. sojae infection and identified various regulatory patterns among miRNAs, genes, and transcription factors.

Summary: This study investigated the pathotype and genetic diversity of Phytophthora sojae, the causal agent of Phytophthora root and stem rot of soybean, in soil samples from Illinois, Indiana, Kentucky, and Ohio. The results showed that there was a moderate level of population differentiation between these states and also between fields within the same state. Cluster analysis detected the presence of P. sojae population structure across neighboring states. The findings support the hypothesis of occasional outcrossing events and highlight the potential impact of gene flow on resistance genes.

Summary: The study found that local air temperature greatly contributed to differences in azoxystrobin tolerance among geographic populations of the pathogen, and both among-population and within-population variations in azoxystrobin tolerance increased as experimental temperatures increased. Additionally, isolates with higher azoxystrobin tolerance adapted to a broader thermal niche.

Summary: The study found that increasing agricultural diversity through crop rotations, especially potato-rice rotation, significantly improves social, economic, and ecological benefits in rice production. However, rationalizing fertilizer application is necessary to enhance resource and investment efficiency. Internalizing externalities and incentivizing farmers to adopt crop rotation methods for sustainable rice production are important strategies proposed in the research.

Summary: Genetic variation is crucial for pathogen adaptation to environmental stresses, with pathogens lacking genetic variation having reduced survival and proliferation. The study on Phytophthora infestans found low sequence variation in the eEF-l alpha protein, indicating a potential compensatory role of post-translational modifications and structural changes in overcoming adaptive disadvantages.

Summary: This study shows that genetic diversity of potato populations influences the evolution of fungicide resistance in Phytophthora infestans, resulting in increased sensitivity to fungicides and reduced genetic variation available for developing resistance. These effects are independent of fungicide biochemical properties and are likely due to host selection for pathogen strains with different fungicide responses. Agricultural practices promoting crop diversification can reduce fungicide usage and mitigate the risk of fungicide resistance development in pathogens, contributing to food security and ecological sustainability.

Summary: Effector genes play critical roles in plant-pathogen interactions. The evolution of the Avr4 gene in Phytophthora infestans involves high genetic diversity and C-terminal truncation as a main mutation mechanism. Local air temperature influences the evolution of effector genes, potentially through adaptation to circumvent plant immune responses.

Summary: Phytophthora infestans is a destructive oomycete pathogen specialized in growing sporangiophore through opened stomata, but the specific metabolic pathways manipulated in potatoes to control stomatal opening are still unclear. Research showed that stomatal movement is crucial for potato immune response to P. infestans, involving guard cell death and closure. The pathogen appears to manipulate metabolic processes in guard cells to evade stomatal defense responses.

Summary: The interaction between Filipendula ulmaria and its rust pathogen Triphragmium ulmariae on the islands of the Skeppsvik archipelago in northern Sweden over 30 years showed that while the host metapopulation plateaued, the pathogen metapopulation experienced greater change. Disease incidence initially rose before declining in the last decade, while prevalence of disease in infected populations declined steadily. This study highlighted the impact of pathogen on long-term dynamics of host populations, indicating a potential cascade of changes in community species composition and diversity.

Summary: Elevated temperatures resulting from global warming pose new challenges to natural and agricultural sustainability. This study examines the contribution of mitochondrial genomes (mtDNA) to thermal adaptation using Phytophthora infestans isolates. The analysis reveals significant variation in mtDNA frequency, intrinsic growth rate, and spatial distribution, with the latter strongly associated with local climatic conditions. The study emphasizes the importance of mtDNA intervention in future disease management.

Summary: Infectious plant diseases pose a significant threat to global agriculture, economy, and ecology. There is a concern that these diseases may worsen with climate change, and computer modeling provides an opportunity to address this issue. This study highlights the problems with current modeling strategies and emphasizes the need to incorporate evolutionary principles into polytrophic, eco-evolutionary frameworks to enhance predictions. It discusses the potential feedback of evolutionary shifts induced by climate change on future plant disease epidemics and the role of technological advances in generating and integrating relevant knowledge for better modeling predictions.

Summary: Glycogen synthase kinase 3 (GSK3) family members are highly conserved protein kinases in mammals and plants, playing a pivotal role in the perception and transduction of diverse signals involved in plant development and stress responses. Recent research has shown that GSK3s are involved in plant adaptation to various stresses and their crosstalk with hormones. Understanding the molecular mechanisms of GSK3s in plant stress responses provides opportunities for developing stress-resilient crops using genetic engineering technology.

Summary: Environmental exposure to hazardous materials, including cadmium, can cause reproductive toxicity through oxidative stress and inflammation. In this study, it was found that procyanidin oligosaccharide B2 (PC-B2) protected against cadmium-induced uterine toxicity by increasing antioxidant enzymes, reducing proinflammatory cytokines, and inhibiting cadmium deposition in the uterus. Interestingly, PC-B2 also promoted beneficial gut microbiota and inhibited harmful microbiota, further protecting the uterus. This study provides insights into the mechanisms of cadmium-induced toxicity and suggests the potential use of PC-B2 in preventing reproductive toxicity caused by cadmium exposure.

Summary: Modelling the yield loss of crops due to pathogens is challenging, but this study successfully developed a dynamic simulation model that integrates an epidemiological model and a crop growth model. The model was able to accurately predict the yield losses caused by late blight disease in potato crops using meteorological variables. The study also highlighted the impact of disease growth rate and time of infection on yield reduction, as well as the potential effects of climate change on disease management in potato production.
