In Colombia, it was first found on nursery plants and later in plantations associated with basal cankers on young trees. In this study, we explored the population diversity of the pathogen in Colombia by analyzing 136 isolates collected from diseased nursery plants (2005–2007) and plantation trees (2017 and 2020). These were sourced from different geographical regions and Pinus species. Genotyping was performed using 10 microsatellite markers, while mating types were identified with PCRs targeting the MAT1 locus. Using microsatellites, a total of 33 multilocus haplotypes were detected. Genetic diversity indices showed low levels of diversity in both the overall collection and in specific collection groupings. The data also suggested that a small number of isolates had unique origins in the country (p < .05), and relatively low levels of population differentiation were detected between the nursery and plantation collections. All the isolates were scored as having the MAT1-1 mating type, and no evidence for the random association among microsatellite alleles (p = .0001) was found. Overall, these data suggest that F. circinatum was introduced into Colombia a small number of times, likely on seed for nursery production. Furthermore, the data also indicate that the pathogen has spread from nurseries to the plantations via asexual reproduction and on asymptomatic plants. This has resulted in a highly clonal F. circinatum population in Colombia that has resulted from accidental introductions of the pathogen into a production nursery.","PeriodicalId":55153,"journal":{"name":"Forest Pathology","volume":"54 3","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/efp.12864","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141245631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The vascular wilt disease caused by C. lukuohia has been recently described and is responsible for the widespread ROD epidemic on Hawai'i Island. However, the role of C. huliohia in ROD development and tree death is not clear. Artificial inoculation of field-grown ʻōhiʻa with C. huliohia and dissections of naturally infected, early symptomatic forest trees were conducted to confirm pathogenicity on field grown trees and the pattern of internal colonization. In two trials, crowns of trees with main stems inoculated with C. huliohia were visually healthy at the time of tree harvest after 43–55 days in the first trial, and after 91 days in the second trial. However, elliptical inner bark cankers underlain by reddish-brown xylem were associated with the inoculation points. Similar canker and stain symptoms were found on stems and branches of ʻōhiʻa (24–26 cm trunk diameter) naturally infected by C. huliohia. This xylem stain manifested as multiple distinct elliptical cankers or the coalescing of multiple cankers. The pathogen was commonly isolated from the perimeter of the stained outer sapwood and to a depth of 4 cm. The coalescence of multiple cankers was associated with the crown symptoms observed on the naturally infected forest trees that were dissected. Multiple C. huliohia infections that lead to coalescing cankers which subsequently girdle stems likely occurs over one or more years compared to the shorter time (e.g., months) required for C. lukuohia-caused death to occur.","PeriodicalId":55153,"journal":{"name":"Forest Pathology","volume":"54 3","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141245526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The disease spreads primarily through wind-driven rain and farm implements, and its host range is limited, affecting mango, cashew, and pepper plants. BBS is characterized by dark, angular lesions with elevated borders on infected leaves and fruits in the lower and upper parts of the tree canopy. Infected plants display numerous tiny water-soaked black lesions on leaves, fruits, and stems. Early symptoms on leaves include tiny, veined, water-soaked patches with angular black dots and occasionally chlorotic spots. Managing BBS presents challenges, but various control measures have shown effectiveness in different regions. Integrated disease control measures, such as cultural methods and removing diseased plant parts, could further reduce BBS prevalence in the field.

Despite this special attention, several Cryphonectria species were not recognized as such for a long time. This also affected the identity of eight isolates with outdated names that have been deposited in our laboratory since 1954. The present study reconstructs the history of the Cryphonectria cultures M282–M289 using primary bibliographic sources. To verify the species identity, all isolates were DNA barcoded and taxonomic affiliation was assessed using a phylogenetic approach. The taxonomic identity combined with the history of the isolates confirms that the chestnut blight epidemic (Cryphonectria parasitica) in Spain was caused by the planting of Asian chestnuts and that the first documented case of bark canker in 1940 was caused by Cryphonectria radicalis on Japanese chestnuts imported from France. The history of isolate M289 could be traced back to CBS 165.32, which proved to be the oldest preserved isolate of the rare Cryphonectria naterciae, confirming the presence of this fungus in Europe for at least 100 years. Based on the ITS barcoding of the 32-year-old type specimen, Cryphonectria decipiens must be reclassified as a later synonym of Cryphonectria radicalis. The reconstruction of the history of isolates M282–M289 takes us on a scientific journey from Italy to France, Spain and Portugal in the early twentieth century and offers new insights into the historical context of the invasion of Cryphonectria parasitica in Europe.","PeriodicalId":55153,"journal":{"name":"Forest Pathology","volume":"54 2","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/efp.12857","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140632076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Oriental beech (Fagus orientalis) is one of the most valuable forest tree species in the Hyrcanian forests. Bark necrosis and bleeding spots of oriental beech were observed in Savadkuh forests in Mazandaran province during summer 2021. Ten samples were collected from symptomatic oriental beech trees. The bark canker symptoms included stem tissue necrosis, dark brown to black spots on the trunk, bleeding with dark exudates and dark lesions in the inner bark. Twenty-six strains of culturable bacteria were isolated from the samples which in culture were predominantly round, convex, smooth with entire margins on nutrient agar and a metallic green sheen pigment on eosin-methylene blue (EMB) agar. Fourteen strains induced necrosis and browning of the tissues around the inoculation sites on acorns after 2 weeks. Five representative strains also caused dieback in twigs of oriental beech 3 weeks after inoculation. These bacteria were Gram-negative, catalase positive and oxidase negative. All strains produced colonies with a green metallic sheen on EMB agar. Strains were negative in tests for starch and gelatine hydrolysis or production of levan. A phylogenetic tree based on concatenated sequences of gyrB and infB genes, of representative strains well as in each of the single gene-based phylogenetic trees, indicated that these strains clustered with Brenneria alni NCPPB 3934T with high bootstrap values. To the best of our knowledge, this is the first report of B. alni associated with bark necrosis and bleeding spots on oriental beech.","PeriodicalId":55153,"journal":{"name":"Forest Pathology","volume":"54 2","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140348655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
