Lately, producers report a steep rise in the incidence of brown rot disease caused by the fungus Gnomoniopsis smithogilvyi (Gnomoniaceae, Diaporthales), which results in severe chestnut rot. The pathogen is considered an emerging pathogen in many countries worldwide (Italy, France, Switzerland, Australia, New Zealand). This study aimed at (a) exploring the incidence of the brown rot disease in Vria (Regional Unit of Pieria, Region of Central Makedonia, Greece), (b) isolating and identifying the causal agent of the disease, (c) exploring the fungus presence at different phenological stages of the chestnut trees, and (d) implementing species-specific Bar- High Resolution Melting Analysis (HRM) for the early detection of G. smithogilvyi in chestnuts. G. smithogilvyi occurrence in chestnut tissues was more severe in June (59 %), nearly disappeared in July (19 %) and August (7 %) and increased again during harvesting time in September (57 %). This result could be attributed to a sum of different factors, including climate conditions. Moreover, it was demonstrated that G. smithogilvyi can be identified using a Bar-HRM analysis of chestnut tissues (buds, flowers and nuts). Results of this study clearly demonstrate that Bar-HRM can be used for the accurate, rapid and reliable identification of G. smithogilvyi universally on infected samples from different localities.</div>","PeriodicalId":12683,"journal":{"name":"Fungal biology","volume":null,"pages":null},"PeriodicalIF":2.9,"publicationDate":"2024-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141433868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To explore the virulence mechanisms of this pathogen, we created a null mutation of the transcription factor gene FoAce2 (encoding F. oxysporum angiotensin converting enzyme 2). Deletion of FoAce2 resulted in slower growth, decreased aerial mycelia and conidiation, and a significant decrease in fungal virulence against banana hosts relative to those of the wild-type (WT) fungus. Additionally, transmission electron microscopy showed that the cell wall was thicker in the FoAce2 deletion mutants. Consistent with this finding, the cell wall glucose level was decreased in the ΔFoAce2 mutants compared with that in the WT and complemented strain, ΔFoAce2-C1. Complementation with the WT FoAce2 gene fully reversed the mutant phenotypes. Analysis of the transcriptome of ΔFoAce2 and the WT strain showed alterations in the expression levels of many genes associated with virulence and growth.

Some fungal isolates produce water soluble melanin (pyomelanin) which is excerted out of the hyphae into the surrounding environment. Pyomelanin, a polymer of homogentisate, exhibits antimicrobial, UV screening, antioxidative, and anti-inflammatory activities and recent studies also show that pyomelanin could find use in space travel as radiation shield.

We report for the first time that Amorosia littoralis occurs as a root endophyte in mangrove species including Avicennia marina, Bruguiera cylindrica and Bruguiera gymnorhiza and produces pyomelanin.

Although ecological importance and root-associating lifestyles of Archaeorhizomyces can be postulated, morphological aspects of fungal body and root colonization are largely unknown due to the scarcity of cultures. We obtained three unidentified Archaeorhizomyces isolates from ericoid mycorrhizal (ErM) roots of Rhododendron scabrum and Rhododendron × obtusum collected in Japan. To advance our understanding of lifestyle of the genus, we investigated their general morphology, phylogeny, and in vitro root-colonizing ability in ericoid mycorrhizal hosts, Vaccinium virgatum and Rhododendron kaempferi. Some morphological characteristics, such as slow glowing white-to-creamy-colored colonies and formation of yeast-like or chlamydospore-like cells, were shared between our strains and two described species, Archaeorhizomyces finlayi and Archaeorhizomyces borealis, but they were phylogenetically distant. Our strains were clearly distinguished as two undescribed species based on morphology and phylogenetic relationship. As seen in typical ErM fungi, both species frequently formed hyphal coils within vital rhizodermal cells of ErM plants in vitro. The morphology of hyphal coils was also different between species. Consequently, two novel species, Archaeorhizomyces notokirishimae sp. nov. and Archaeorhizomyces ryukyuensis sp. nov., were described.</div>","PeriodicalId":12683,"journal":{"name":"Fungal biology","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2024-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141279069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, we evaluated the effects of temperature, pH, and relative humidity (RH) on the growth of P. paneum OM1, which was isolated from pears, and its patulin production. The fungal strain showed the highest growth rate at 25 °C and pH 4.5 on pear puree agar medium (PPAM) under 97 % RH, while it produced the highest amount of patulin at 20 °C and pH 4.5 on PPAM under 97 % RH. Moreover, RT-qPCR analysis of relative expression levels of 5 patulin biosynthetic genes (patA, patE, patK, patL, and patN) in P. paneum OM1 exhibited that the expression of the 4 patulin biosynthetic genes except patL was up-regulated in YES medium (patulin conducive), while it was not in PDB medium (patulin non-conducive).
