Various fungal species from the genus Cytospora / Valsa can infect tree bark and cause tissue rot, and Valsa mali ( Vm ) is responsible for the most severe tree branch deaths and yield losses. Since AVC was first reported in Japan in 1903, the pathogen species, biological characteristics, infection and pathogenesis, spore dissemination, and disease cycle have been intensively investigated. Based on the new cognition of the disease dynamics, the disease control strategy has shifted from scraping diseased tissue to protecting the bark from infection. In this review, we summarize new knowledge of the Vm infection process mediated by various kinds of virulence factors, including cell wall degrading enzymes, toxins, effectors, microRNA-like RNAs, and pathogenic signaling regulators. We also introduce progress in evaluating germplasm resources and identifying disease response-related genes in apples. In addition, we elaborate current understanding of spore dissemination and disease cycles in orchards and disease prevention techniques. Finally, we provide recommendations for developing more cost-effective strategies for controlling AVC by applying genetic resistance and biological fungicides.","PeriodicalId":20098,"journal":{"name":"Phytopathology Research","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135437067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a powerful tool, HTS aids in identifying pathogens and enhances disease management strategies by detecting novel and emerging pathogens, tracking disease outbreaks, and contributing to developing disease-resistant cultivars. Despite these benefits, the implementation of HTS faces obstacles due to the complexity of data interpretation and economic factors that affect its widespread adoption. This comprehensive review summarizes the strengths, limitations, and opportunities associated with using HTS in managing plant diseases. The article also delves into the prospects of HTS, incorporating technological advancements, synergy with complementary methodologies, capacity-building initiatives, and the development of best practices and guidelines. By acknowledging and addressing these obstacles while harnessing the full capabilities of HTS, we advocate for a refined approach to managing plant diseases. This approach is critical for ensuring global food security, especially in the context of a growing global population and climate change.","PeriodicalId":20098,"journal":{"name":"Phytopathology Research","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135824554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The rice bacterial leaf streak pathogen Xanthomonas oryzae pv. oryzicola ( Xoc ) harbors three Xrv proteins, the XrvA, XrvB, and XrvC. Here, we report that in Xoc , the XrvB but not XrvA and XrvC is involved in negative regulation of the type III secretion system (T3SS) encoded by hrp genes. As with other Xanthomonas spp., the T3SS is an essential virulence determinant of Xoc and the expression of the hrp genes in Xoc is controlled by the HrpG/HrpX regulatory cascade. HrpG positively regulates the expression of HrpX, which in turn activates the transcription of the hrp genes. We provide evidences to demonstrate that the XrvB binds to the promoter region of hrpG and represses its transcription. Furthermore, we found that XrvB production was induced in the Xoc cells cultured in a nutrient-rich medium compared to a hrp -inducing minimal medium. We also found that in Xoc , the hrpG expression level is inversely correlated with the content of XrvB, and XrvB occupancy at hrpG promoter region is positively correlated with XrvB levels. Our data suggest that XrvB is a determinative factor controlling the expression levels of HrpG. In addition, mutation analysis revealed that the Xoc XrvB also plays positive roles in regulating bacterial growth, cell motility, and stress tolerance. Our findings provide important insights into the molecular mechanism of T3SS expression regulation in Xoc .","PeriodicalId":20098,"journal":{"name":"Phytopathology Research","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135980654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
