Excessive application of site-specific fungicides to control the pathogen has led to the selection of strains possessing target site alterations associated with resistance to these fungicides and/or strains overexpressing efflux transporters associated with multidrug resistance (MDR). MDR in B. cinerea has been correlated with the overexpression of atrB and mfsM2, encoding an ATP-binding cassette (ABC) and a major facilitator superfamily (MFS) transporter, respectively. However, it remains unknown whether other transporters may also contribute to the MDR phenotype. In the current study, the transcriptome of a B. cinerea multidrug-resistant (MDR) field strain was analysed upon exposure to the fungicide fludioxonil, and compared to the B05.10 reference strain. The transcriptome of this field strain displayed significant differences as compared to B05.10, including genes involved in sugar membrane transport, toxin production and virulence. Among the induced genes in the field strain, even before exposure to fludioxonil, were several putatively encoding ABC and MFS transmembrane transporters. Overexpression of a highly induced MFS transporter gene in the B05.10 strain led to an increased tolerance to the fungicides fluopyram and boscalid, indicating an involvement in efflux transport of these compounds. Overall, the data from this study give insights towards better understanding the molecular mechanisms involved in MDR and fitness cost, contributing to the development of more efficient control strategies against this pathogen.", "doi": "10.1111/mpp.70004", "pmid": "39244735", "labels": {"NGI Uppsala (SNP&SEQ Technology Platform)": "Service", "NGI Short read": "Service", "National Genomics Infrastructure": "Service"}, "xrefs": [{"db": "pmc", "key": "PMC11380696"}], "notes": [], "created": "2024-10-21T11:12:58.472Z", "modified": "2024-10-21T11:13:08.829Z"}, {"entity": "publication", "iuid": "656b4a9c8ec1478e9c2baa2806ac8cb5", "links": {"self": {"href": "https://publications.scilifelab.se/publication/656b4a9c8ec1478e9c2baa2806ac8cb5.json"}, "display": {"href": "https://publications.scilifelab.se/publication/656b4a9c8ec1478e9c2baa2806ac8cb5"}}, "title": "Verticillium longisporum phospholipase VlsPLA2 is a virulence factor that targets host nuclei and modulates plant immunity.", "authors": [{"family": "Rafiei", "given": "Vahideh", "initials": "V", "orcid": "0000-0003-0021-9734", "researcher": {"href": "https://publications.scilifelab.se/researcher/c453e43d63594937aa2efd03e37bee1e.json"}}, {"family": "V\u00e9l\u00ebz", "given": "Heriberto", "initials": "H", "orcid": "0000-0003-3146-0555", "researcher": {"href": "https://publications.scilifelab.se/researcher/c9a3146e50264c32b9074894e32892a0.json"}}, {"family": "Piombo", "given": "Edoardo", "initials": "E", "orcid": "0000-0003-2830-1967", "researcher": {"href": "https://publications.scilifelab.se/researcher/4ff26b84d14643f3ae4e45a23cd2107b.json"}}, {"family": "Dubey", "given": "Mukesh", "initials": "M", "orcid": "0000-0001-7393-366X", "researcher": {"href": "https://publications.scilifelab.se/researcher/da047e9540e344cc93b54a96d5c82b72.json"}}, {"family": "Tzelepis", "given": "Georgios", "initials": "G", "orcid": "0000-0001-6144-2185", "researcher": {"href": "https://publications.scilifelab.se/researcher/60b2114dba0640d3aeecba0c4e729ce0.json"}}], "type": "journal article", "published": "2023-09-00", "journal": {"title": "Mol.

In the present study, we investigated the role of secreted PLA2 (VlsPLA2 ) in Verticillium longisporum, a fungal phytopathogen that mostly infects plants belonging to the Brassicaceae family, causing severe annual yield loss worldwide. Expression of the VlsPLA2 gene, which encodes active PLA2 , is highly induced during the interaction of the fungus with the host plant Brassica napus. Heterologous expression of VlsPLA2 in Nicotiana benthamiana resulted in increased synthesis of certain phospholipids compared to plants in which enzymatically inactive PLA2 was expressed (VlsPLA2 \u0394CD ). Moreover, VlsPLA2 suppresses the hypersensitive response triggered by the Cf4/Avr4 complex, thereby suppressing the chitin-induced reactive oxygen species burst. VlsPLA2 -overexpressing V. longisporum strains showed increased virulence in Arabidopsis plants, and transcriptomic analysis of this fungal strain revealed that the induction of the gene contributed to increased virulence. VlsPLA2 was initially localized to the host nucleus and then translocated to the chloroplasts at later time points. In addition, VlsPLA2 bound to the vesicle-associated membrane protein A (VAMPA) and was transported to the nuclear membrane. In the nucleus, VlsPLA2 caused major alterations in the expression levels of genes encoding transcription factors and subtilisin-like proteases, which play a role in plant immunity. In conclusion, our study showed that VlsPLA2 acts as a virulence factor, possibly by hydrolysing host nuclear envelope phospholipids, which, through a signal transduction cascade, may suppress basal plant immune responses.", "doi": "10.1111/mpp.13352", "pmid": "37171182", "labels": {"Global Proteomics and Proteogenomics": "Service", "Swedish Metabolomics Centre": "Service"}, "xrefs": [{"db": "pmc", "key": "PMC10423322"}], "notes": [], "created": "2023-08-30T07:09:49.551Z", "modified": "2025-10-17T13:03:13.547Z"}, {"entity": "publication", "iuid": "c7e444c1c6864297b04b31cb10b66b98", "links": {"self": {"href": "https://publications.scilifelab.se/publication/c7e444c1c6864297b04b31cb10b66b98.json"}, "display": {"href": "https://publications.scilifelab.se/publication/c7e444c1c6864297b04b31cb10b66b98"}}, "title": "A Verticillium longisporum pleiotropic drug transporter determines tolerance to the plant host \u03b2-pinene monoterpene.", "authors": [{"family": "Rafiei", "given": "Vahideh", "initials": "V", "orcid": "0000-0003-0021-9734", "researcher": {"href": "https://publications.scilifelab.se/researcher/c453e43d63594937aa2efd03e37bee1e.json"}}, {"family": "Ruffino", "given": "Alessandra", "initials": "A", "orcid": "0000-0002-7039-2957", "researcher": {"href": "https://publications.scilifelab.se/researcher/acfbbc82f59b4fbc8a9ea0e6b8515e51.json"}}, {"family": "Persson Hod\u00e9n", "given": "Kristian", "initials": "K", "orcid": "0000-0003-0354-0662", "researcher": {"href": "https://publications.scilifelab.se/researcher/e8b41e8e41574ee6bcb55df3b0d145d9.json"}}, {"family": "Tornkvist", "given": "Anna", "initials": "A", "orcid": "0000-0002-6215-6727", "researcher": {"href": "https://publications.scilifelab.se/researcher/d36e5404f2a841019aa1aeac9c8c7ec9.json"}}, {"family": "Mozuraitis", "given": "Raimondas", "initials": "R", "orcid": "0000-0002-1719-2294", "researcher": {"href": "https://publications.scilifelab.se/researcher/213ecb5deb7d4d06901f461424d964cf.json"}}, {"family": "Dubey", "given": "Mukesh", "initials": "M", "orcid": "0000-0001-7393-366X", "researcher": {"href": "https://publications.scilifelab.se/researcher/da047e9540e344cc93b54a96d5c82b72.json"}}, {"family": "Tzelepis", "given": "Georgios", "initials": "G", "orcid": "0000-0001-6144-2185", "researcher": {"href": "https://publications.scilifelab.se/researcher/60b2114dba0640d3aeecba0c4e729ce0.json"}}], "type": "journal article", "published": "2022-02-00", "journal": {"title": "Mol.
