Abstract
Succinate dehydrogenase (SDH) is an integral component of the tricarboxylic acid cycle (TCA) and respiratory electron transport chain (ETC), targeted by succinate dehydrogenase inhibitors (SDHIs). Fusarium asiaticum is a prominent phytopathogen causing Fusarium head blight (FHB) on wheat. Here, we characterized the functions of the FaSdhA, FaSdhB, FaSdhC1, FaSdhC2, and FaSdhD subunits. Deletion of FaSdhA, FaSdhB, or FaSdhD resulted in significant growth defects in F. asiaticum. The FaSdhC1 or FaSdhC2 deletion mutants exhibited substantial reductions in fungal growth, conidiation, virulence, and reactive oxygen species (ROS). The FaSdhC1 expression was significantly induced by pydiflumetofen (PYD). The ΔFaSdhC1 mutant displayed hypersensitivity to SDHIs, whereas the ΔFaSdhC2 mutant exhibited resistance against most SDHIs. The transmembrane domains of FaSdhC1 are essential for regulating mycelial growth, virulence, and sensitivity to SDHIs. These findings provided valuable insights into how the two SdhC paralogues regulated the functional integrity of SDH, ROS homeostasis, and the sensitivity to SDHIs in phytopathogenic fungi.

Functional roles of α 1-, α 2-, β 1-, β 2-tubulin in vegetative growth, microtubule assembly and sexual reproduction of Fusarium graminearum. Appl Environ Microbiol 2021; 87:e0096721. [PMID: 34378994 DOI: 10.1128/aem.00967-21] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/20/2022] Open
Abstract
The plant pathogen Fusarium graminearum contains two α-tubulin (α1 and α2) isotypes and two β-tubulin isotypes (β1 and β2). The functional roles of these tubulins in microtubule assembly are not clear. Previous studies showed that α1- and β2-tubulin deletion mutants showed severe growth defects and hypersensitivity to carbendazim, which have not been well explained. Here, we investigated the interaction between α- and β-tubulin of F. graminearum. Co-localization experiments demonstrated that β1- and β2-tubulin are co-localized. Co-immunoprecipitation experiment suggested that β1-tubulin binds to both α1- and α2-tubulin and β2-tubulin can also bind to α1- or α2-tubulin. Interestingly, deletion of α1-tubulin increased the interaction between β2-tubulin and α2-tubulin. Microtubule observation assays showed that deletion of α1-tubulin completely disrupted β1-tubulin-containing microtubules and significantly decreased β2-tubulin-containing microtubules. Deletion of α2-, β1- or β2-tubulin respectively had no obvious effect on the microtubule cytoskeleton. However, microtubules in α1- and β2-tubulin deletion mutants were easily depolymerized in the presence of carbendazim. The sexual reproduction assay indicates that α1- and β1-tubulin deletion mutants could not produce asci and ascospores. These results implied that α1-tubulin may be essential for the microtubule cytoskeleton. However, our Δα1-2×α2 mutant (α1-tubulin deletion mutant containing two copies of α2-tubulin) exhibited a normal microtubule network, growth and sexual reproduction. Interestingly, the Δα1-2×α2 mutant was still hypersensitive to carbendazim. In addition, both β1-tubulin and β2-tubulin were found to bind the mitochondrial outer membrane voltage-dependent anion channel (VDAC), indicating they could regulate the function of VDAC. Importance: In this study, we found that F. graminearum contains four different α-/β-tubulin heterodimers (α1-β1, α1-β2, α2-β1 and α2-β2) and they assemble together into a single microtubule. Moreover, α1-, α2-tubulins are functionally interchangeable in microtubule assembly, vegetative growth and sexual reproduction. These results provide more insights into functional roles of different tubulins of F. graminearum which could be helpful for purification of tubulin heterodimers and developing new tubulin-binding agents.

Abstract
In Fusarium graminearum, a trichothecene biosynthetic complex known as the toxisome forms ovoid and spherical structures in the remodelled endoplasmic reticulum (ER) under mycotoxin-inducing conditions. Previous studies also demonstrated that disruption of actin and tubulin results in a significant decrease in deoxynivalenol (DON) biosynthesis in F. graminearum. However, the functional association between the toxisome and microtubule components has not been clearly defined. In this study we tested the hypothesis that the microtubule network provides key support for toxisome assembly and thus facilitates DON biosynthesis. Through fluorescent live cell imaging, knockout mutant generation, and protein-protein interaction assays, we determined that two of the four F. graminearum tubulins, α1 and β2 tubulins, are indispensable for DON production. We also showed that these two tubulins are directly associated. When the α1 -β2 tubulin heterodimer is disrupted, the metabolic activity of the toxisome is significantly suppressed, which leads to significant DON biosynthesis impairment. Similar phenotypic outcomes were shown when F. graminearum wild type was treated with carbendazim, a fungicide that binds to microtubules and disrupts spindle formation. Based on our results, we propose a model where α1 -β2 tubulin heterodimer serves as the scaffold for functional toxisome assembly in F. graminearum.

The Dis1/Stu2/XMAP215 Family Gene FgStu2 Is Involved in Vegetative Growth, Morphology, Sexual and Asexual Reproduction, Pathogenicity and DON Production of Fusarium graminearum. Front Microbiol 2020; 11:545015.

Abstract
The conserved Dis1/Stu2/XMAP215 microtubule association proteins (MAPs) family plays an important role in microtubule dynamics, nucleation, and kinetochore-microtubule attachments. However, function of Dis1/Stu2/XMAP215 homolog in plant pathogenic fungi has not been determined. Here, we identified and investigated the Dis1/Stu2/XMAP215 homolog (FGSG_10528) in Fusarium graminearum (FgStu2p). Co-localization experiment and co-immunoprecipitation (Co-IP) assay demonstrated that FgStu2p is a microtubule associated protein. Besides, FgStu2 could also interact with Fgγ-tubulin and presumed FgNdc80, which suggested that the FgStu2 gene might associate with microtubule nucleation and kinetochore-microtubule attachments like Dis1/Stu2/XMAP215 homologs in other species. Moreover, the FgStu2 promoter replacement mutants (FgStu2-Si mutants) produced twisted hyphae and decreased growth rate. Microscope examination further showed that the microtubule polymerization was reduced in FgStu2-Si mutants, which could account for the aberrant morphology. Although the microtubule polymerization was affected in FgStu2-Si mutants, the FgStu2-Si mutants didn't show highly increased sensitivity to anti-microtubule fungicide carbendazim (methyl benzimidazol-2-ylcarbamate [MBC]). In addition, the FgStu2-Si mutants exhibited curved conidia, decreased number of conidial production, blocked ability of perithecia production, decreased pathogenicity and deoxynivalenol (DON) production. Taken together, these results indicate that the FgStu2 gene plays a crucial role in vegetative growth, morphology, sexual reproduction, asexual reproduction, virulence and deoxynivalenol (DON) production of F. graminearum, which brings new insights into the functions of Dis1/Stu2/XMAP215 homolog in plant pathogenic fungi.

Comparative acetylome analysis reveals the potential roles of lysine acetylation for DON biosynthesis in Fusarium graminearum. BMC Genomics 2019; 20:841. [PMID: 31718553 PMCID: PMC6852988 DOI: 10.1186/s12864-019-6227-7] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2019] [Accepted: 10/25/2019] [Indexed: 01/07/2023] Open
Abstract
Background Fusarium graminearum is a destructive fungal pathogen of wheat, barley and other small grain cereals. During plant infection, the pathogen produces trichothecene mycotoxin deoxynivalenol (DON), which is harmful to human and livestock. FgGCN5 encodes a GCN5 acetyltransferase. The gene deletion mutant Fggcn5 failed to produce DON. We assumed that lysine acetylation might play a key regulatory role in DON biosynthesis in the fungus. Results In this study, the acetylome comparison between Fggcn5 mutant and wild-type strain PH-1 was performed by using affinity enrichment and high resolution LC-MS/MS analysis. Totally, 1875 acetylated proteins were identified in Fggcn5 mutant and PH-1. Among them, 224 and 267 acetylated proteins were identified exclusively in Fggcn5 mutant and PH-1, respectively. Moreover, 95 differentially acetylated proteins were detected at a significantly different level in the gene deletion mutant:43 were up-regulated and 52 were down-regulated. GO enrichment and KEGG-pathways enrichment analyses revealed that acetylation plays a key role in metabolism process in F. graminearum. Conclusions Seeing that the gens playing critical roles in DON biosynthesis either in Fggcn5 mutant or PH-1. Therefore, we can draw the conclusion that the regulatory roles of lysine acetylation in DON biosynthesis in F. graminearum results from the positive and negative regulation of the related genes. The study would be a foundation to insight into the regulatory mechanism of lysine acetylation on DON biosynthesis.

Abstract
The filamentous ascomycete Fusarium graminearum contains two β-tubulin genes TUB1 and TUB2 that differ in functions during vegetative growth and sexual reproduction. To further characterize their functional relationship, in this study we determined the co-localization of Tub1 and Tub2 and assayed their expression levels in different mutants and roles in DON production. Tub1 co-localized with Tub2 to the same regions of microtubules in conidia, hyphae, and ascospores. Whereas deletion of TUB1 had no obvious effect on the transcription of TUB2 and two α-tubulin genes (TUB4 and TUB5), the tub2 mutant was up-regulated in TUB1 transcription. To assay their protein expression levels, polyclonal antibodies that could specifically detect four α- and β-tubulin proteins were generated. Western blot analyses showed that the abundance of Tub1 proteins was increased in tub2 but reduced in tub4 and tub5 mutants. Interestingly, protein expression of Tub4 and Tub5 was decreased in the tub1 mutant in comparison with the wild type, despite a lack of obvious changes in their transcription. In contrast, deletion of TUB2 had no effect on translation of TUB4 and TUB5. Ectopic expression of Tub2-mCherry partially recovered the growth defect of the tub1 mutant but did not rescue its defect in sexual reproduction. Expression of Tub1-GFP in the tub2 mutant also partially rescued its defects in vegetative growth, suggesting that disturbance in the balance of α- and β-tubulins contributes to mutant defects. The tub2 but not tub1 mutant was almost blocked in DON biosynthesis. Expression of TRI genes, toxisome formation, and DON-related cellular differentiation were significantly reduced in the tub2 mutant. Overall, our results showed that Tub1 and Tub2 share similar subcellular localization and have overlapping functions during vegetative growth but they differ in functions in DON production and ascosporogenesis in F. graminearum.

Abstract
Hsp70 proteins play important roles in protein folding in the budding yeast, but their functions in pathogenic fungi are largely unknown. Here, we found that Fusarium graminearum Hsp70 proteins FgSsb, FgSsz and their cochaperone FgZuo formed a complex. This complex was required for microtubule morphology, vacuole fusion and endocytosis. More importantly, the β2-tubulin FgTub2 and SNARE protein FgVam7 were identified as targeting proteins of this complex. We further found that the complex FgSsb-FgZuo-FgSsz controlled sensitivity of F. graminearum to the antimicrotubule drug carbendazim and cold stress via regulating the folding of FgTub2. Moreover, this complex assisted the folding of FgVam7, subsequently modulated vacuole fusion and responses to heavy metal, osmotic and oxidative stresses. In addition, the deletion of this complex led to dramatically decreased deoxynivalenol biosynthesis. This study uncovers a novel regulating mechanism of Hsp70 in multiple stress responses in a filamentous fungus.

Abstract
In yeasts, the end-binding protein 1 (EB1) homologs regulate microtubule dynamics, cell polarization, and chromosome stability. However, functions of EB1 orthologs in plant pathogenic fungi have not been characterized yet. Here, we observed that the FgEB1 deletion mutant (ΔFgEB1) of Fusarium graminearum exhibits twisted hyphae, increased hyphal branching and curved conidia, indicating that FgEB1 is involved in the regulation of cellular polarity. Microscopic examination further showed that the microtubules of ΔFgEB1 exhibited less organized in comparison with those of the wild type. In addition, the lack of FgEB1 also altered the distribution of polarity-related class I myosin via the interaction with the actin. On the other hand, we identified four core septins as FgEB1-interacting proteins, and found that FgEB1 and septins regulated conidial polar growth in the opposite orientation. Interestingly, FgEB1 and FgKar9 constituted another complex that modulated the response to carbendazim, a microtubule-damaging agent specifically. In addition, the deletion of FgEB1 led to dramatically decreased deoxynivalenol (DON) biosynthesis. Taken together, results of this study indicate that FgEB1 regulates cellular polarity, fungicide sensitivity and DON biosynthesis via different interactors in F. graminarum, which provides a novel insight into understanding of the biological functions of EB1 in filamentous fungi.
