Abstract&Keyword Cite

Abstract :

Flumequine (Flu) is a fluoroquinolone veterinary antibiotic, which is easy to accumulate in animals, and Flu residues may cause a latent risk to human physiological health. In this study, a high-affinity monoclonal antibody (2.09 x 109 M-1) to specifically recognize Flu (anti-Flu mAb) was prepared, and then the lateral flow immunochromatographic strips (LFIS) with excellent sensitivity and specificity were developed by combining mAbs with nanoparticles. The linear detection ranges of LFIS based on gold particles (AuNP-LFIS) and gold nanoflowers (AuNF-LFIS) were 1.95-250 ng/mL and 0.39-100 ng/mL, respectively, and two types of LFIS showed high sensitivity and accuracy in actual sample detection. It is noteworthy that the AuNF-LFIS exhibited a higher sensitivity compared to that of the AuNP-LFIS. The LFIS developed in this study were considered to have great application potential in monitoring food safety because of its superiorities including simple operation, high sensitivity, prompted speed and good specificity.

Abstract&Keyword Cite

Abstract :

Furosine, a hazardous compound mainly produced by the Maillard reaction in food at high temperatures, has been shown to exert cytotoxic effects on cells and cause liver damage after excessive consumption. Hence, it is desirable to develop correlative sensitive and robust immunoassays for furosine detection in real-world samples. In this study, Ovalbumin-furosine (OVA-furo) conjugates were employed as the immunogens for animal immunization, and a hybridoma (1C3) secreting an anti-furosine monoclonal antibody (mAb) was successfully screened. The purified 1C3 mAb exhibited high specificity and affinity (7.4 x 108 L/mol), and an indirect competitive ELISA (ic-ELISA) based on the 1C3 mAb was developed for the detection of furosine. The linear detection range of the ic-ELISA was 6.03-817.85 ng/mL, with a limit of detection (LOD) value of 2 ng/mL. Colloid gold nanospheres(AuNP-) and nanoflower gold-particles(AuNF)-based strips were also established based on this antibody, which had qLOD values and linear ranges of 40 and 20 ng/mL and 40-140 and 20-90 ng/mL, respectively. All the immunoassays showed good detection performance, indicating that these immunoassays have the potential for practical application for the inexpensive detection of furosine in real-world samples.

Abstract&Keyword Cite

Abstract :

Aspergillus flavus and its secondary metabolites aflatoxins pose a significant threat to the health of humans, animals, and plants. Therefore, there is an urgent need to control A. flavus contamination. AfverB plays a key role in the aflatoxin gene cluster; however, its function and mechanism in fungal development and virulence remain poorly understood. In this study, we constructed afVerB gene deletion mutants (triangle afVerB-1 and triangle afVerB-2) and two CYP domain mutants (afVerB(triangle D1) and afVerB(triangle D2)) through homologous recombination. Phenotype analysis revealed that, via its two CYP domains, AfVerB is deeply involved in fungal morphogenesis and aflatoxin synthesis. Insect and crop colonization models revealed that AfVerB plays a key role in the fungus's ability to infect hosts, and stress experiments discovered that AfVerB plays a significant role in the response to various environmental stresses, which explains why AfVerB is a key factor in fungal infection to some extent. RT-qPCR analysis demonstrated that AfVerB performs its bio-function through corresponding regulatory factors. We ultimately discovered that AfVerB is deeply involved in cell membrane stress stability, thereby participating in the regulation of fungal drug resistance (sensitive to AMB and resistant to VOR in this study). The CYP domain of AfVerB, particularly its second CYP domain, is crucial for the execution of its biological functions. This study elucidated the regulatory mechanisms by which AfVerB regulates fungal pathogenicity and aflatoxin biosynthesis, providing potential strategies for controlling A. flavus and its aflatoxin contamination.

Succinylated acetyl-CoA carboxylase contributes to aflatoxin biosynthesis, morphology development, and pathogenicity in Aspergillus flavus SCIE
期刊论文 | 2024 , 413 | INTERNATIONAL JOURNAL OF FOOD MICROBIOLOGY
Abstract&Keyword Cite

Abstract :

Acetyl-CoA carboxylase (ACC), which catalyzes acetyl-CoA to produce malonyl-CoA, is crucial for the synthesis of mycotoxins, ergosterol, and fatty acids in various genera. However, its biofunction in Aspergillus flavus has not been reported. In this study, the accA gene was deleted and site-mutated to explore the influence of ACC on sporulation, sclerotium formation, and aflatoxin B1 (AFB1) biosynthesis. The results revealed that ACC positively regulated conidiation and sclerotium formation, but negatively regulated AFB1 production. In addition, we found that ACC is a succinylated protein, and mutation of lysine at position 990 of ACC to glutamic acid or arginine (accAK990E or accAK990R) changed the succinylation level of ACC. The accAK990E and accAK990R mutations (to imitate the succinylation and desuccinylation at K990 of ACC, respectively) downregulated fungal conidiation and sclerotium formation while increasing AFB1 production, revealing that the K990 is an important site for ACC's biofunction. These results provide valuable perspectives for future mechanism studies of the emerging roles of succinylated ACC in the regulation of the A. flavus phenotype, which is advantageous for the prevention and control of A. flavus hazards.

Abstract :

As a filamentous pathogenic fungus with high-yield of aflatoxin B1, Aspergillus flavus is commonly found in various agricultural products. It is crucial to develop effective strategies aimed at the prevention of the contamination of A. flavus and aflatoxin. Hexokinase AfHxk1 is a critical enzyme in fungal glucose metabolism. However, the role of AfHxk1 in A. flavus development, aflatoxin biosynthesis, and virulence has not yet been explored. In this study, afHxk1 gene deletion mutant (Delta afHxk1), complementary strain (Com-afHxk1), and the domain deletion strains (afHxk1(Delta D1) and afHxk1(Delta D2)) were constructed by homologous recombination. Phenotype study and RT-qPCR revealed that AfHxk1 upregulates mycelium growth and spore and sclerotia formation, but down regulates AFB1 biosynthesis through related classical signaling pathways. Invading models and environmental stress analysis revealed that through involvement in carbon source utilization, conidia germination, and the sensitivity response of A. flavus to a series of environmental stresses, AfHxk1 deeply participates in the regulation of pathogenicity of A. flavus to crop kernels and Galleria mellonella larvae. The construction of domain deletion strains, afHxk1(Delta D1) and afHxk1(Delta D2), further revealed that AfHxk1 regulates the morphogenesis, mycotoxin biosynthesis, and the fungal pathogenicity mainly through its domain, Hexokinase_2. The results of this study revealed the biological role of AfHxk1 in Aspergillus spp., and might provide a novel potential target for the early control of the contamination of A. flavus.

Abstract :

Tetrodotoxin (TTX) could result in serious diseases due to its extremely high neurotoxicity. Thus, it is of great importance to measure TTX for food safety. In this study, an anti-TTX monoclonal antibody with good specificity and high affinity was used to develop the immunochromatographic test strips (ICTS). Gold nanoflower (AuNF) with multiple branches and latex microsphere (LM) with large particle size as signal reporters were employed for improving the sensitivity of test strips. Both AuNF and LM probes are stable, and the developed ICTS were specific to TTX, demonstrating no cross-reactivity with other marine toxins. The linear range of AuNF- and LM-based strips for TTX was 9.49-330.98 ng/mL and 5.40-443.19 ng/mL, respectively. The limit of detection (LOD) of AuNF- and LM-based strips was determined to be 9.49 ng/mL and 5.40 ng/mL, respectively. In summary, the developed ICTS based on AuNF and LM signal probes displayed enhancement of sensitivity and provided rapid and specific detection of TTX.

Abstract :

Reversible phosphorylation by protein kinases and phosphatases plays a central role in regulating cellular processes. However, knowledge of the functions of protein phosphatase 2C (PP2C) S/T phosphatases in Aspergillus flavus has been unreported until now. Here, we have identified seven members of the PP2C family of protein phosphatases in A. flavus. Evolutionary and functional analyses indicated that two redundant PP2C phosphatases, Ptc1 and Ptc2, are highly conserved and regulate conidia development, aflatoxin synthesis, seed infection, and autophagic vesicle formation. The cytoplasmic proteins Ptc1 and Ptc2 exhibit nuclear infiltration after DNA damage-induced autophagy. Their degradation is closely linked to autophagy induction. The Asp residue coordinated with Mg2+ is critical for phosphatase Ptc1 and Ptc2 activity, thermal stability, and biofunction in A. flavus. An immunoprecipitation-mass spectrometry proteomic investigation indicated that 133 proteins co-interact with Ptc1 and Ptc2. Among these proteins, phosphoglycerate kinase 1 (PGK1) interacts with Ptc1 and Ptc2 and shows high levels of phosphorylation in ?ptc1, ?ptc2, and ?ptc1/ptc2 mutants. Furthermore, PGK1 S203 phosphorylation levels are associated with aflatoxin synthesis and autophagic vesicle formation. Overall, these findings contribute to our understanding of the roles and mechanisms of PP2C family phosphatases in A. flavus and highlight their importance in various cellular processes. Furthermore, it reveals a new regulation model in A. flavus, where Ptc1 and Ptc2 activate autophagy and aflatoxin synthesis by regulating PGK1.

Abstract :

Heterotrimeric G-proteins play crucial roles in growth, asexual development, and pathogenicity of fungi. The regulator of G-protein signaling (RGS) proteins function as negative regulators of the G proteins to control the activities of GTPase in G alpha subunits. In this study, we functionally characterized the six RGS proteins (i.e., RgsA, RgsB, RgsC, RgsD, RgsE, and FlbA) in the pathogenic fungus Aspergillus flavus. All the aforementioned RGS proteins were also found to be functionally different in conidiation, aflatoxin (AF) biosynthesis, and pathogenicity in A. flavus. Apart from FlbA, all other RGS proteins play a negative role in regulating both the synthesis of cyclic AMP (cAMP) and the activation of protein kinase A (PKA). Additionally, we also found that although RgsA and RgsE play a negative role in regulating the FadA-cAMP/PKA pathway, they function distinctly in aflatoxin biosynthesis. Similarly, RgsC is important for aflatoxin biosynthesis by negatively regulating the GanA-cAMP/PKA pathway. PkaA, which is the cAMP-dependent protein kinase catalytic subunit, also showed crucial influences on A. flavus phenotypes. Overall, our results demonstrated that RGS proteins play multiple roles in the development, pathogenicity, and AF biosynthesis in A. flavus through the regulation of G alpha subunits and cAMP-PKA signals. IMPORTANCE RGS proteins, as crucial regulators of the G protein signaling pathway, are widely distributed in fungi, while little is known about their roles in Aspergillus flavus development and aflatoxin. In this study, we identified six RGS proteins in A. flavus and revealed that these proteins have important functions in the regulation of conidia, sclerotia, and aflatoxin formation. Our findings provide evidence that the RGS proteins function upstream of cAMP-PKA signaling by interacting with the G alpha subunits (GanA and FadA). This study provides valuable information for controlling the contamination of A. flavus and mycotoxins produced by this fungus in pre- and postharvest of agricultural crops.

GTPase Rac Regulates Conidiation, AFB1 Production and Stress Response in Pathogenic Fungus Aspergillus flavus SCIE

Abstract&Keyword Cite

Abstract :

As a member of the Rho family, Rac plays important roles in many species, including proliferation, differentiation, apoptosis, DNA damage responses, metabolism, angiogenesis, and immunosuppression. In this study, by constructing Rac-deleted mutants in Aspergillus flavus, it was found that the deletion of Rac gene led to the decline of growth and development, conidia production, AFB1 toxin synthesis, and seed infection ability of A. flavus. The deletion of Rac gene also caused the disappearance of A. flavus sclerotium, indicating that Rac is required for sclerotium formation in A. flavus. The sensitivity of Rac-deficient strains responding to cell wall stress and osmotic pressure stress increased when compared to A. flavus WT. The Western blot result showed that mitogen-activated serine/threonine-protein kinase Slt2 and mitogen-activated protein kinase Hog1 proteins were no longer phosphorylated in Rac-deficient strains of A. flavus, showing that Rac may be used as a molecular switch to control the Slt2-MAPK cascade pathway and regulate the osmotic Hog-MAPK cascade pathway in A. flavus in response to external stress. Altogether, these results indicated that Rac was involved in regulating the growth and development, conidia formation and AFB1 synthesis, and response to cell wall stress and osmotic pressure stress in A. flavus.
