Fusarium wilt,caused by Fusarium oxysporum f.sp.cubense Tropical Race 4(Foc TR4),remains one of the most devastating threats to global banana cultivation.Conventional management strategies,including chemical treatments and resistant cultivars,have shown limited efficacy and scalability.Emerging evidence highlights the banana microbiome—comprising diverse bacterial and fungal communities in the rhizosphere,endosphere,and phyllosphere—as a critical ally in suppressing Foc through mechanisms such as competitive exclusion,antibiosis,biofilm formation,and systemic resistance induction.This review synthesizes recent findings on microbiome-mediated disease suppression,emphasizing the functional roles of key microbial taxa like Pseudomonas,Bacillus,and Trichoderma that contribute to natural disease resistance.It also explores innovative strategies for harnessing these microbes via bioinoculants,crop rotation,organic amendments,and microbiome-based management.Advances in metagenomics and microbial community analysis offer promising tools to build disease-resilient agroecosystems.However,field variability,regulatory constraints,and ecological complexities remain key challenges.Overall,this review highlights how integrating ecological understanding with practical microbiome applications can support sustainable management of Fusarium wilt in banana systems. 展开更多

In order to elucidate the relationship between the pathogen carriage rate in seeds of muskmelon(Cucumis melo L.)and the incidence rate of Fusarium wilt of muskmelon(FWM),as well as to identify potential biological control agents against FWM,this study conducted both pot and field experiments to evaluate the efficacy of Gongzhulingmycin on FWM and its impact on muskmelon yield.The results indicated that the pathogen carriage rates of different species in muskmelon seeds varied significantly,showing a positive correlation with disease incidence during the seedling stage.The results from pot tests indicated that in comparison to the control,disease indices were significantly reduced following treatment with prochloraz and 100 times Gongzhulingmycin at both 7 days and 14 days post-emergence of FWM symptoms.Concurrently,root growth was enhanced.Field experiment outcomes demonstrated that relative to the control,there was a decrease in FWM incidence during the fruit-setting stage,along with an increase in theoretical output per square kilometer for muskmelon.Although the efficacy of Gongzhulingmycin against FWM was lower than that observed for prochloraz,it exhibited significant effects on biomass enhancement and disease resistance.Therefore,it showed promise as a potential biological control agent for managing FWM. 展开更多

Lilies(genus Lilium)play a significant role in the global cut-flower industry,but they are highly susceptible to fusarium wilt caused by Fusarium oxysporum.However,Lilium regale,a wild lily species,exhibits remarkable resistance to F.oxysporum.To investigate the quantitative resistance of L.regale to fusarium wilt,a comprehensive multi-omics analysis was conducted.Upon inoculation with F.oxysporum,L.regale roots showed a significant accumulation of phenylpropane metabolites,including lignin precursors,flavonoids,and hydroxycinnamic acids.These findings were consistent with the upregulated expression of phenylpropanoid biosynthesis-related genes encoding various enzymes,as revealed by transcriptomics and proteomics analyses.Furthermore,metabolomics and proteomics data demonstrated differential activation of monoterpenoid and isoquinoline alkaloid biosynthesis.Colorimetry and high-performance liquid chromatography analyses revealed significantly higher levels of total flavonoids,lignin,ferulic acid,phlorizin,and quercetin contents in L.regale scales compared with susceptible lily‘Siberia’scales during F.oxysporum infection.These phenylpropanes exhibited inhibitory effects on F.oxysporum growth and suppressed the expression of pathogenicity-related genes.Transcriptional regulatory network analysis suggested that ethylene-responsive transcription factors(ERFs)may positively regulate phenylpropanoid biosynthesis.Therefore,LrERF4 was cloned and transiently overexpressed in the fusarium wilt-susceptible Oriental hybrid lily‘Siberia’.The overexpression of LrERF4 resulted in increased levels of total flavonoids,lignin,ferulic acid,phlorizin,and quercetin,while the silencing of LrERF4 in L.regale through RNAi had the opposite effect.In conclusion,phenylpropanoid metabolism plays a crucial role in the defense response of L.regale against fusarium wilt,with LrERF4 acting as a positive regulator of phenylpropane biosynthesis. 展开更多

In order to clarify the main pathogens of tomato Fusarium wilt in Shanxi Province, China, morphological identification, elongation factor 1 alpha （EF-1α） sequence analysis, specific primer amplification and pathogenicity tests were applied to study the isolates which were recovered from diseased plants collected from 17 different districts of Shanxi Province. The results were as follows： 1） Through morphological and molecular identification, the following 7 species of Fusarium were identified： F. oxysporum, F. solani, F. verticillioides, F. subglutinans, F. chlamydosporum, F. sporotrichioides, and F. semitectum; 2） 56 isolates of F. oxysporum were identified using specific primer amplification, among which, 29, 5 and 6 isolates were respectively identified as F. oxysporum f. sp. lycopersici physiological race 1, race 2, and race 3; 3） pathogenicity test indicated the significant pathogenicity of F. oxysporum, F. solani, F. verticillioides, and F. subglutinans to tomato plant. Therefore, among these 4 species confirmed as pathogenic to tomato in Shanxi, the highest isolation rate （53.3％） corresponded to F. oxysporum. Three physiological species, race 1, race 2, and race 3 of F. oxysporum f. sp. lycopersici are detected in Shanxi, among which race 1 is the most widespread pathogen and is also considered as the predominant race. 展开更多

Strawberry Fusarium wilt (SFW) is a systematic soil-borne disease caused by Fusarium oxysporum f.sp.fragaria (Fof),which infects the vascular bundles,blocking water and nutrient transport from roots to the aboveground.It is a severe pathogen which spreads rapidly and destroys strawberry production.Finding a way to control this disease is of great scientific value and practical importance.In this study,three fungi were isolated from the vascular tissues of sick strawberries in the field.After DNA sequencing,they were identified as Fof,Aspergillus fumigatus and Trichoderma harzianum,respectively,among which the first two are pathogens and the third is a probiotic.All fungi were controlled by thiophanate-methyl (TM),a commercial fungicide.On PDA medium,20 mg·L-15-aminolevulinic acid (ALA),a natural non-protein amino acid,promoted T.harzianum proliferation,but inhibited Fof and A.fumigatus.In confrontation test,the growth of Fof or A.fumigatus was inhibited by T.harzianum and exogenous ALA promoted T.harzianum growth but significantly inhibited the pathogen growth.When three species of fungi were separately or combinedly inoculated on healthy strawberry plants,T.harzianum promoted plant growth and development while Fof or A.fumigatus caused growth retardation,where Fof directly caused leaf yellowing and plant wilting.When the plants inoculated with different fungus were treated with ALA,the results turned out that ALA alleviated SFW symptoms by bidirectionally promoting T.harzianum proliferation and inhibiting Fof and A.fumigatus.Thus,ALA might be used in comprehensively controlling SFW in strawberry industry. 展开更多

The variant LM1 was previously obtained using embryogenic cell suspension cultures of sweetpotato variety Lizixiang by gamma-ray induced mutation, and then its characteristics were stably inherited through six clonal generations, thus this mutant was named LM1. In this study, systematic characterization of salt tolerance and Fusarium wilt resistance were performed between Lizixiang and mutant LM1. LM1 exhibited significantly higher salt tolerance compared to Lizixiang. The content of proline and activities of superoxide dismutase（SOD） and photosynthesis were significantly increased, while malonaldehyde（MDA） and H_2O_2 contents were significantly decreased compared to that of Lizixiang under salt stress. The inoculation test with Fusarium wilt showed that its Fusarium wilt resistance was also improved. The lignin, total phenolic, jasmonic acid（JA） contents and SOD activity were significantly higher, while H_2O_2 content was significantly lower in LM1 than that in Lizixiang. The expression level of salt stress-responsive and disease resistance-related genes was significantly higher in LM1 than that in Lizixiang under salt and Fusarium wilt stresses, respectively. This result provides a novel and valuable material for improving the salt tolerance and Fusarium wilt resistance of sweetpotato. 展开更多

Fusarium wilt(FW)is one of the most common cotton diseases in the world.Identification of QTLs conferring resistance to FW is key for the incorporation of resistance genes into elite cultivars.Two intraspecific(cross between Gossypium hirsuturn L.)and one interspecific(cross between Gossypium hirsutum L.and Gossypium bardence L.)F2 populations were constructed by using a highly resistant cultivar and crossing it to a susceptible cultivar with 154,79,and 148 offsprings,respectively.Simple sequence repeats(SSR)were used to screen genomic regions closely linked to FW resistance.The results showed that five QTLs associated with FW resistance were detected in two intraspecific populations using a composite interval mapping method under four different conditions.Four of these loci located on Chr.2/Chr.17 neighboring markers JESPR304 or CIR305 which explained 13.1 to 45.9%of the phenotypic effect.Furthermore,JESPR304 and CIR305 were previously testified and found to be tightly linked.It is possible that these four QTLs detected under different conditions were the same resistance QTL/gene.We consider that there is the possibility of a major FW resistant gene in intraspecific populations.In the interspecific mapping populations two QTLs were detected on Chr.9 and Chr.12/26 which explained great phenotypic variance of 49.4 and 45.7%.As the location of QTLs for FW resistance among the intraspecific and the interspecfic populations were totally different,it is suggested that there may be different resistance mechanisms between G.bardence L.and G.hursutum L.Thus,the present research provides an opportunity to understand the genetic control of resistance to FW in Gossypium hirsutum and Gossypium bardence and to conduct MAS in breeding programs to develop FW resistant cultivars. 展开更多

An improved electrochemiluminescence polymerase chain reaction(ECL-PCR)method was developed and applied to detect Fusarium wilt.Briefly,the internal transcribed spacer(ITS)sequence of Fusarium oxysporumf,sp Cubense(FOC)was amplified by PCR.Two universal fragments,which were complimentary to Ru(bpy)3^2+(TBR)labeled probe and Biotin labeled probe,respectively,were connected to the tail of primers so that all the PCR products got universal sequences.Then biotin labeled probes and TBR labeled probes were hybridized with the PCR products at the same time.Through the specific interaction between biotin and streptavidin,the PCR products were captured by streptavidin coated magnetic bead and then detected by ECL assay.The experiment results showed that the healthy banana samples and infected ones can be discriminated by this ECL-PCR method.This improved ECL-PCR approach is useful in Fusarium wilt detection due to its high sensitivity,simplicity and stability. 展开更多

[Objective] This study aimed to isolate and purify the antifungal protein against Fusarium oxysporum f. sp niveum （FON） from Bacillus subtilis XG-I. [Method] The crude protein was obtained by using fractional precipitation with am- monium sulfate, then chromatography using both DEAE-Sepharose FF anion ex- change and Sephacryl S-100 gel filtration columns was adopted for further purifica- tion of the protein, followed by MALDI-TOF-MS analysis of the structure of the at- tained protein which was antagonistic to FON. [Result] The result from MALDI-TOF- MS analysis suggested that the antifungal protein extracted from strain XG-1 was highly homologous to the flagellin （gi114278900） deriving from B. subtilis, with a pro- tein score of 248 and a coverage rate of 63%. It was thus speculated that this an- tagonistic protein was a kind of flagellin with a molecular mass of 30.6 kD. [Conclusion] The results from this study provide theoretical basis for clarifying the mechanisms of the action of strain XG-1 as well as important references for the preven- tion and control of watermelon Fusarium wilt. 展开更多

Molecular identification on diploid and tetraploid watermelon breeding lines which were resistant to Fusarium wilt was carried out with the published dCAPS marker ＂4451_fon＂ which was closely linked with resistance gene of Fusarium wilt race 1. The results showed that all the diploid and tetraploid lines expressed as re- sistant genotype, which were defined as Fusarium wilt-resistant materials. The re- sults were consistent with that of artificial inoculation identification. Molecular identifi- cation results also indicated that the resistant lines were homozygote, and the Fusarium wilt-resistant gene would not separate or lose during the future self- crossed purification. Therefore, resistance selection would not be necessary in their progeny populations. The study results thought that dCAPS marker ＂4451_fon＂ could be applied on molecular marker assisted selection for Fusarium wilt resistance breeding in watermelon to increase breeding selection efficiency and accelerate breeding progress. 展开更多

Fusarium species were reported to produce biofilms.Biofilms are superficial societies of microbes bounded and endangered by being situated or taking place outside a cell or cells.The most destructive fungal diseases caused by phytopathogens are as a result of biofilms formation.Fusarium wilt of banana(Panama disease)is caused by a soil-borne pathogen called Fusarium oxysporum f.sp.cubense.Fusarium oxysporum occurs in a form of a species complex(FOSC)which encompasses a crowd of strains.Horizontal genetic factor transfer may donate to the observed assortment in pathogenic strains,while sexual reproduction is unknown in the FOSC.Fusarium wilt is a notorious disease on several crops worldwide.Yield loss caused by this pathogen is huge,and significant to destroy crop yields annually,thereby affecting the producer countries in various continents of the world.The disease is also resistant to various synthetic chemical fungicides.However,excessive use of synthetic fungicides during disease control could be lethal to humans,animals,and plants.This calls for alternative eco-friendly management of this disease by targeting the biofilms formation and finally suppressing this devastating phytopathogen.In this review,we,therefore,described the damage caused by Fusarium wilt disease,the concept of filamentous fungal biofilms,classical control strategies,sustainable disease control strategies using essential oils,and prevention and control of vegetables Fusarium wilt diseases. 展开更多

Pumpkin(Cucurbita moschata)has been widely used as cucumber(Cucumis sativus L.)rootstock to defend against Fusarium wilt(FW)and increase cucumber yields and profits.However,the resistance genes and mechanisms underlying the FW tolerance in pumpkin are poorly understood.Here we analyzed the transcriptome of pumpkin inoculated with the cucumber FW causal agent Fusarium oxysporum f.sp.cucumerinum(Foc),and obtained 3152 and 4735 upregulated genes induced by Foc at 24h after Foc inoculation compared with at 0h and 24h non-inoculated control,respectively.Next,404 common differentially expressed genes(DEGs)were screened using the criterion log2 FPKM(fold change)≥2.In total,206 of 404 DEGs were predominantly expressed in roots,which is the first tissue that Foc contacts and invades.140 DEGs were selected and classified into four groups(pathogenesis resistance,secondary metabolism-related,transcription factor and signal binding)based on their functional descriptions.Then,29 genes having high expression levels were selected to investigate the expression patterns induced by a Foc inoculation.Among them,16 genes were significantly induced by Foc and showed high expression levels at various treatment time points.These candidate genes may act as positive regulators of FW resistance in pumpkin and provide effective resources for improving cucumber FW resistance through breeding programs. 展开更多

This study is aimed at assessing the ability of two endophytic bacteria originally isolated from healthy oil palm roots, Pseudomonas sp. （UPMP3） and Burkholderia sp. （UPMB3） to induce resistance in susceptible Berangan banana against Fusarium oxysporum race 4 （FocR4）. Increased accumulation of resistance-related enzymes such as peroxidase （PO）, phenylalanine ammonia lyase （PAL）, lignithioglycolic acid （LTGA）, and pathogenesis-related （PR） proteins （ehitinase and β-1,3-glucanase） has been observed in plantlets treated with endophytic bacteria UPMP3 and UPMB3 singly or as mixture under glasshouse conditions. Pre-inoculation of banana plantlets with UPMP3 showed a significant reduction in Fusarium wilt incidence 72 d after challenged inoculation with FocR4. UPMB3 was less effective in suppressing Fusarium wilt compared to UPMP3, whereas, the mixture of both endophytes showed an intermediate effect. Based on these results, it is concluded that UPMP3 could be a promising biological control agent that can trigger resistance against Fusarium wilt in susceptible Berangan banana. 展开更多

The amount of phenol compounds in the soil increased after adding organic material into the soil. It was found that p-hydroxybenzoic acid, p-coumaric acid and frulic acid alleviated Fusarium wilt of cucumber, the alleviating effect of p-hydroxybenzoic acid was the best, followed by p-coumaric acid and frulic acid. The total amount of bacterial, actinomyces and fungus in high phenol compounds treatment decreased than that of control treatment, while the microorganisms’ amount in low phenol compounds treatment increased. Phenol compounds inhibit the growth of pathogen. 展开更多

Studying about the effect of four pseudomonas and two serratia isolates on growth of Fusarium oxysporum showed that, Pseudomonasfluorescens No.2 ＆ No.3 and Serratia marcescens No.2 gave highest inhibition zones which were 37.33, 35,00 and 31.33 mm, respectively. Evaluating about the effect ofpseudomonas and serratia culture filtrates at three concentrations （10, 25, 50%） on the linear growth and spore germination ofFusarium oxysporum revealed that, all filtrates of the tested isolates reduced the mycelial growth and spore germination of F. oxysporum. All filtrates of the tested isolates at 50% concentration completely inhabited spore germination ofF. oxysporurn. Culture filtrates of Pseudomonasputida and Serratia marcensens No.2 at 50% concentration reduced the mycelial growth of F. oxysporurn by 80.74 and 80.37% respectively. In this respect, all tested isolates made lysis to mycelial of F. oxysporum except Pseudornonasfluorescens No.3. Effect of treating cucumber seeds with cell suspension of pseudomonas and serratia isolates on incidence of Fusarium wilt disease revealed that all isolates were effective in reducing disease incidence and disease severity and increasing the percentage of healthy plants compared to the control. Pseudornonasfluorescens No.3 and Serratia marcensens No.2 were the best isolates and completely prevented the disease incidence. 展开更多
