This study examined how soil type and temperature influence the composition and dominance of soilborne pathogens. Blighted soybeans were collected from upland and paddy fields nationwide (2020-2022) and isolated at 25°C and 35°C. Isolation frequency was significantly affected by soil type, temperature, and their interaction. M. phaseolina predominated in upland soils but was rarely recovered from paddy fields. In contrast, Fusarium spp. associated with soybean blight, Diaporthe longicolla causing pod and stem blight, and Calonectria ilicicola causing red crown rot were frequently isolated but showed reduced recovery or pathogenicity at 35°C. Growth and pathogenicity assays revealed a temperature-driven shift in dominance: various pathogens were virulent at 25°C, while M. phaseolina showed enhanced growth and severity at 35°C. Greenhouse experiments demonstrated that moisture stress (reduced irrigation) significantly increased charcoal rot severity, strengthening the competitive advantage of M. phaseolina. These findings suggest that soil type and temperature interact to restructure pathogen communities. M. phaseolina is emerging primarily in upland systems where high temperature coincides with moisture stress, necessitating targeted management under climate change. While culture-based recovery reflects a pathogen's potential under specific thermal conditions, it may not directly represent actual field density.","PeriodicalId":20173,"journal":{"name":"Plant Pathology Journal","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147778357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ralstonia solanacearum species complex, the causal agent of bacterial wilt disease in numerous plant hosts, deploy a conserved subset of RipG effectors containing leucine-rich repeats and an F-box motif that collectively contribute to virulence and host specificity. RipG effectors are proposed to hijack the eukaryotic ubiquitin-proteasome machinery through the recruitment of substrates to host Skp1-cullin-F-box ubiquitinligase complexes via RipG F-box/host Skp1 adaptor interactions. However, only few host proteins have been reported to interact with RipG effectors. Here, using a surrogate type III delivery and a heterologous expression systems, we show that RipG6 can suppress plant pattern-triggered immunity in an F-box-dependent manner. We further identified a tomato receptor-like cytoplasmic kinase (SlRLCK-VIII-6) as an interactor of RipG6 in yeast and plant cells. SlRLCK-VIII-6 stability was reduced when co-expressed with RipG6 but not with the RipG6 variant lacking the F-box motif. Lastly, we provide evidence that Nicotiana benthamiana and Arabidopsis thaliana homologs of SlRLCK-VIII-6 can act as positive regulators of plant immune signaling. Together, our work supports a model where RipG6 destabilizes RLCK-VIII-6 possibly via its recruitment in a host ubiquitin-ligase complex in order to suppress plant immunity. Further research into RLCK-VIII role will enhance our understanding of the manipulation of plant immunity signaling by pathogen effectors.","PeriodicalId":20173,"journal":{"name":"Plant Pathology Journal","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147778420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are crucial for intercellular communication and signaling. Plant pathogens have developed a diverse array of mechanisms to exploit the PD. There is increasing evidence that PD is actively involved in plant defense responses. Viral movement proteins alter PD architecture, cytoskeletal organization, and associated protein complexes, facilitating intercellular movement of viral genomes. Similarly, bacterial and fungal effectors target PD to suppress defense signaling and enhance colonization. During pathogen recognition, PD undergo dynamic closure as part of pattern-triggered immunity, largely mediated by callose deposition at PD neck regions. Over the past few years, significant progress has been made in elucidating the functions of PD in plantpathogen interaction. However, there are still numerous critical areas that require attention. The current review emphasizes the crucial role of pathogen-PD interactions in shaping PD-molecular flux and explores their impact on hormone signaling and different cell types during intercellular movement of pathogens. This review emphasizes the need for deeper insights into PD regulation during plant-pathogen interactions, focusing on molecular targets exploited by pathogens. Elucidating the molecular mechanisms underlying PD-mediated defense will advance our understanding of plant immunity and aid in developing innovative strategies for sustainable disease management.","PeriodicalId":20173,"journal":{"name":"Plant Pathology Journal","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147729508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While viral genetic variations modulating virus adaptation to biotic stresses have been reported, whether and how they affect virus interactions with abiotic stresses such as high temperature remain unknown. Here, we report the impact of AV2 mutations on the life cycle of squash leaf curl China virus (SLCCNV), a bipartite begomoviruses. We first conducted sequence analysis and identified a naturally-occurring mutation at position 35 in AV2 that changes the codon TGG to TAG. Followed analysis revealed that this mutation did not significantly impact SLCCNV infectivity and transmission under both ambient and high temperatures. Next, we changed the start codon of AV2 to stop codon. While the mutation of start codon did not impact SLCCNV infection under ambient temperature, under high temperatures mutant SLCCNV displayed decreased infectivity. We then examined the underpinnings of AV2 function, and found that AV2 cannot compensate for the function of other viral genes and its expression relative to other viral genes was not induced at high temperature. Moreover, protein encoded by AV2 suppressed posttranscriptional gene silencing under both ambient and high temperatures. Our study unravels a novel function of viral factors in the regulation of begomovirus infection under high temperature, and sheds new lights on virus adaptation to abiotic stresses.","PeriodicalId":20173,"journal":{"name":"Plant Pathology Journal","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147691437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Non-thermal plasma (NTP; cold atmospheric plasma) is a residuefree, near-ambient technology that generates reactive oxygen and nitrogen species (RONS) with strong virucidal activity. This review summarizes major sources of NTP, including dielectric barrier discharges, plasma jets, and corona/streamer discharges; plasma chemistry in gas and liquid phases; molecular mechanisms of virus inactivation, including capsid protein oxidation/denaturation, limited lipid peroxidation in enveloped plant viruses, and genome damage that suppresses replication. Evidence from plant virus studies indicates that highly stable viruses lose infectivity and that waterborne inactivation is efficient, supporting the use of NTP and plasma-activated water as practical tools for sanitizing irrigation water, recirculating hydroponic solutions, and contact surfaces. Emerging greenhouse studies have suggested that plasma-generated oxidants, including ozone, can curb water-mediated dissemination. Hence, we compare NTP with thermotherapy, irradiation, and chemical antiviral approaches, and discuss safety, scalability, and economic considerations. Key priorities for translation include standardized dose and chemistry metrics, infectivity-based endpoints in realistic matrices, scalable reactors that ensure uniform treatment at high throughput, and multi-site validation under commercial production conditions.","PeriodicalId":20173,"journal":{"name":"Plant Pathology Journal","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147691515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we found significant differences in fungicide resistance depending on the type of pathogen and regional differences and performed base sequence analysis of the CYP51 gene on some Alternaria isolates with fungicide resistance to confirm the occurrence of point mutations and amino acid substitutions. However, point mutations were not detected in some resistant Alternaria isolates, suggesting that the resistance of some isolates is possibly unrelated to the alterations in the target site or may be due to genetic variations in unidentified genomic sequence CYP51 gene.
