The raw data were cleaned up using Trimmomatic and checked for quality using FastQC. The sequencing data were assembled using SPAdes, and GeneMark was used to perform gene prediction on the assembly results. The results showed that the genome size of T. polysporum HZ-31 was 39,325,746 bp, with 48% GC content, and the number of genes encoded was 11,998. A total of 148 tRNAs and 45 rRNAs were predicted. A total of 782 genes were annotated in the Carbohydrase Database, 757 genes were annotated to the Pathogen-Host Interaction Database, and 67 gene clusters were identified. In addition, 1023 genes were predicted to be signal peptide proteins. The annotation and functional analysis of the whole genome sequence of T. polymorpha HZ-31 provide a basis for the in-depth study of the molecular mechanism of its herbicidal action and more effective utilization for weed control. Biological sciences/Microbiology Biological sciences/Molecular biology whole genome T. polysporum HZ-31 weeds key genes Figures Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Figure 6 Figure 7 Figure 8 Introduction Weeds are one of the major constraints on crop production, and the weed flora is diverse, consisting of a variety of perennial and annual grasses, broadleaf weeds, and sedges, which includes both parasitic and invasive weed species. Weed control is usually carried out using chemical herbicides and tillage. However, the overuse of these two control strategies poses significant challenges to agricultural production and ecology [1] . As the source of the Three Rivers, protecting the ecological environment in the Tibetan Plateau region is a top priority. This region also has special ecological characteristics such as high altitude, severe cold, strong radiation, and drought [2] , resulting in a very low environmental carrying capacity [3] , and the ecological environment is extremely fragile and vulnerable to damage. The extensive use of chemical herbicides has made the Tibetan Plateau region prone to ecological pollution, weed resistance and other problems. Reducing the amount of chemical herbicides used in response to the special ecological conditions of the region can effectively reduce the pollution of the ecological environment and increase crop yields. Microorganisms and their metabolites have herbicidal activity, and they have received more attention in the field of biocontrol research in recent years [4] . Microbial herbicides developed using microbial metabolites, especially phytopathogenic toxins, are usually safe, environmentally friendly, highly effective and have multiple target sites of action, so they can achieve green and efficient control and disrupt the development of weed resistance [5] . Xylomycetes are soil-borne filamentous fungi that are widely used as a source of biocontrol agents in agriculture [6] . They have effective antagonistic mechanisms [7] such as fungal parasitism [8] , antibiotics [9] or competition against plant pathogens [10] and nematodes [11] .. Some of the active products of M. xylostella have also been shown to exhibit herbicidal activity in recent years. Javaid et al. [12] demonstrated that fermentation filtrates of Trichoderma harzianum Rifai, T. pseudokoningii Rifai, T. reesei Simmons and T. viride Pers. have herbicidal activity against both of the wheat field weeds Phalaris minor L. and Rumex dentatus L. Yin et al. [13] demonstrated that harzianum A and B from T. breviccompacactum showed efficient weed control potential at low concentrations against Brassica chinensis , a Brassica herbaceous plant of the Cruciferae family. Moura et al .[14] demonstrated that methanolic extracts from T. spirale affected the photosynthesis of Senna occidentalis and Ipomoea grandifolia , an herbaceous plant of the genus Ipomoea , thereby exerting a toxic effect on these weeds. While searching for potential herbicide compounds, our laboratory found a strain of the weed causal agent T. arvense var. setosum at the stem base of Cirsium arvense var. setosum that showed highly efficient inhibition of weeds such as Avena fatua L., Chenopodium album L., Polygonum lapathifolium , and others. T. polysporum HZ-31 [15] , which can produce a variety of active substances such as 1,8-propanediol-o-xylene, 2,3-dihydroxypropyl propionate, and others [16] , is a kind of mycobacterial resource with high utilization value in weed biological control. At present, the whole genome sequence of T. polysporum has not been reported at home or abroad, and the use of the whole genome to mine the genes related to the synthesis of pathogenic and bioactive substances of T. polysporum has not been reported. Sequencing the genomes of weed-producing defensive fungi and using bioinformatics methods to search for the disease-causing genes and genes related to synthesis of bioactive substances or signaling pathway components of weed pathogens is an effective method to study the pathogenesis of weed pathogens. In this study, we sequenced the genome of T. polysporum , performed genome sequence analysis and gene function annotation to identify pathogenicity-related genes at the genome-wide level, searched for genes related to secondary metabolite synthesis in the databases and performed a systematic analysis. The results of these analyses provide a scientific basis for the in-depth study of the pathogenesis of T. polysporum in weeds. Material for testing 1.1 Test strains T. polysporum HZ-31 was provided by the Key Laboratory of Integrated Management of Agricultural Pests of Qinghai Province and was stored in the General Microbiology Center of China Microbial Culture Preservation Management Committee (CGNCC No.12867). Methods 2.1 Strain culture The laboratory strain preserved in the slant medium of T. polysporum HZ-31 was transferred into the PDA solid medium, with a sterile perforator with a diameter of 8 mm at the edge of the colony to hit the cake, and was inoculated on an aseptic operating table in 250 mL of sterile PDB liquid medium. Each bottle of inoculation included 5 ~ 8 particles, and was cultured at 25 ℃ on a shaking bed at 180 r/min for 5 ~ 7 d. After filtering with 3 layers of sterile gauze, the mycelium and spores were collected, washed three times with sterile water, frozen in liquid nitrogen and prepared for use. 2.2 Extraction of genomic DNA (gDNA) Genomic DNA was extracted using the Fungal Genomic DNA Extraction Kit. The integrity of the DNA was determined using 1% agarose gel electrophoresis, and the concentration and purity of the DNA were determined using Nanodrop and Qubit. 2.3 Library construction, sequencing, data quality control and assembly The whole genome DNA of T. polysporum HZ-31 was constructed and sequenced by Sangong Bioengineering (Shanghai) Co. The genomic DNA was sequenced using the Illumina II sequencing platform. After library construction, the library size was determined by 2% agarose gel electrophoresis, and the library concentration was measured by a Thermo Qubit 4.0 fluorescence quantification instrument. The raw image data files obtained by Illumina Hiseq™ were converted into raw sequenced reads by CASAVA Base Calling analysis. The raw data quality values and other information were determined, and the quality of the sequencing data of the samples was evaluated visually using FastQC. The raw data were filtered using Trimmomatic, which included removing the following: sequences with N bases; splice sequences in reads; low-quality bases (Q-value < 20) starting from the 3' to 5' direction of reads; low-quality bases (Q-value < 20) starting from the 5' to 3' direction of reads; bases with quality values below 20 in the tails of the reads using the sliding window method (window size of 5 bp); and the reads themselves along with their paired reads with a length of less than 35 nt. The second-generation sequencing data were spliced using SPAdes, which first corrects the sequence errors of the original sequence, then assembles it by multiple Kmer values, and finally synthesizes the assembly results of each Kmer value to obtain the best results. Then GapFiller was used to complement GAP on the contig obtained from splicing, and finally PrInSeS-G was used for sequence correction to correct the editing errors and the insertion-deletions of small fragments during splicing. 2.4 Gene element prediction GeneMark was used for gene prediction of the assembly results, with tRNAscan-SE for tRNA, RNAmmer for rRNA, and Rfam for snRNA, while RepeatModeler was used for the Denovo prediction of repetitive sequences of the assembly results. RepeatMasker was then used to find the position and frequency of occurrence of each type of repetitive sequences on the genomic segments. 2.5 Gene function annotation The protein sequences of the predicted genes were aligned with the NR, SwissProt, TrEMBL, COG, PFAM ( http://pfam.xfam.org/ ), and CDD ( https://www.ncbi.nlm.nih.gov/cdd/ ) databases to obtain protein functional annotation using NCBI BLAST + V2.2.28 software. GO (Gene Ontology) functional annotations were obtained using the SwissProt and TrEMBL databases, and KEGG (Kyoto Encyclopedia of Genes and Genomes) annotations were obtained using KAAS V2.21 software. 2.6 Analysis of disease-causing and secondary metabolite-related genes The gene set protein sequences were aligned to the CAZy database using HMMER3 to obtain their corresponding carbohydrate-active enzyme annotation information. The screening condition was E-value < 1e-5. The gene protein sequences were aligned with the PHI-base database using BLAST to combine the annotation information of the genes and their corresponding pathogenic host interactions to obtain the final annotation results. Secondary metabolite synthesis gene clusters in strain PA-2 were predicted using the antiSMASH 3.0 online tool ( https://fungismash.secondarymetabolites.org ). SignalP software was used to predict the possible signal peptides of T. polysporum HZ-31.

The protein encoding genes for T. polysporum HZ-31 were annotated to the CAZy database with a total of 782 genes(Fig. 6 ), the largest number of which were annotated to the Glycoside hydrolase family with 296 (37.85%); the smallest number of genes were annotated to the Polysaccharide cleavage enzyme family with 11 (1.41%). The remaining genes annotated to glycosyltransferases, sugar esterolytic enzymes, oxidoreductases, and carbohydrate-binding structural domains numbered 155, 139, 116, and 65 genes, respectively, for percentages of 19.82%, 17.77%, 14.83%, and 8.31%, respectively. The most genes annotated to the T. polysporum HZ-31GH family were the genes encoding GH18 with 35, followed by GH5, GH16, and GH3 with 21, 19, and 19, respectively. The most frequently annotated gene in the HZ-31GT family of T. polysporum was the genes encoding GT41, with 50 genes, followed by GT32, GT2, and GT21, with 12, 11, and 8 genes, respectively. 3.4.2 Secondary metabolic gene clusters Secondary metabolites are key factors in the phytotoxic activity of pathogenic fungi, and a variety of phytotoxic secondary metabolites, including polyketides, non-ribosomal peptides, terpenes, and alkaloids, are used to kill host cells. A total of 67 gene clusters were identified in the genome of T. polysporum HZ-31(Fig. 7 ). The highest percentages were in the polyketide synthase gene clusters of type I (T1PKS), non-ribosomal peptide synthase-like gene clusters (NRPS-Like), peptide-like clusters synthesized and post-translationally modified in the fungal ribosome (fungal-RiPP-like), and non-ribosomal peptides (NRPS), and the highest percentage of terpenes (TERPENE), while NRP-metallophore accounted for less. BLAST comparison of all gene clusters of T. polysporum HZ-31 with known secondary metabolite gene clusters revealed that the 1421_g gene in the NRPS-Like, fungal-RiPP-like gene cluster type encoded material that was 100% similar to the choline gene cluster, while the 2916_g and 2919_g genes in the NRPS,T1PKS gene cluster type encoded material that was 66% similar to C. albicans beauvericin. The similarity of the substances encoded by the 2916_g and 2919_g genes to beauvericin was 66%, while the 5536_g genes in the NRPS cluster type showed 100% similarity to verticillin. The 6364_g genes in the NRPS cluster type showed 100% similarity to the peramine/intermediate 1/intermediate 2 genes. The similarity of the 7085_g in the NRPS cluster type to enniatin was 100%, and the similarity of 7561_g in the NRPS cluster type to (-)-Mellein was 100%. The 7905_g gene encoded a substance which showed 100% similarity to trichoxide. The substance encoded by the 4736_g gene in the NRPS-like,T1PKS gene cluster type showed 50% similarity to swainsonine. 3.4.3 PHI pathogenicity related genes PHI annotation of the genomic genes of T. polysporum HZ-31 showed that a total of 757 genes were annotated in the database for pathogen-host interactions(Fig. 8 ). When the pathogen genes were functionally categorized, the highest number of genes were annotated as reduced virulence, 370; followed by unaffected pathogenicity, 244; loss of pathogenicity, 82; lethal, 30; and resistance, 30; chemistry target: resistance to chemical, 15; and effector: plant avirulence determinant, 117, A total of 47 were annotated as increased virulence, hypervirulence. Among them, the GPA1 gene, with a relatively high number of annotations in the Pathogen-Host Interaction Database (PHIDB), was numbered gene9200 in the genome of strain HZ-31, with a total length of 1,062 bp. It encodes the G protein α subunit, which is related to the nutrient growth, sporulation, adherent cell formation, and toxin production of the fungus, and is involved in the pathogenicity of Cryptoccus neo formans, Aspergillus nidulans , Ustilago esculenta , Fusarium graminearum and T.harzianum. The knockdown of the GPA1 gene could cause the complete loss of pathogenicity of F. graminearum GPA1 mutant on wheat spikes [ 18 ] . Further studies have also confirmed that the GPA1 gene can affect adherent cell formation and the expression of several virulence-related genes associated with infestation through the regulation of intracellular cAMP levels. 3.4.4 Signaling peptide proteins A total of 1,023 signal peptide proteins (8.53%) were predicted for T. polysporum HZ-31(Table 8 ).

In this regard, an in-depth study of the intrinsic causes of T. polysporum pathogenicity at the genomic level is of great significance. Therefore, we obtained the genome size of T. polysporum HZ-31 by whole genome sequencing and bioinformatics analysis as 39,325,746 bp, with 48% GC content, and the number of coding genes was 11,998. Among these genes, 148 tRNAs and 45 rRNAs were predicted in the annotated GO, COG and KEGG databases as related to amino acid metabolism, carbohydrate metabolism and lipid metabolism. A variety of carbohydrate-active enzymes secreted by plant pathogens are involved in the degradation of host plant cell walls. Several studies have shown that pathogens from animals and plants utilize carbohydrases and other nutrients to regulate their virulence and adjust their metabolism for successful colonization [ 19 ] . A total of 782 genes were annotated in the carbohydrase database in this study. Members of the glycoside hydrolase family act as virulence factors and modulate plant immune responses during pathogen infection [ 20 ] . Among them, the gene encoding GH3 was annotated in T. polysporum HZ-31, and it was found to encode a β-glucosidase that plays an important role and is a key enzyme in cellulose degradation, which is closely related to the pathogen's infectious characteristics. Wang et al. [ 21 ] found that the cell wall degrading enzyme of Ziziphus jujuba melanogaster , which plays a key role in the pathogenic process, is β-glucosidase, and its activity is the highest in the diseased-healthy junction in the process of infection. Li [ 22 ] found that there were 16 GH3 gene family members in the genome of Aspergillus sphaericus , and the transcripts of most of them were up-regulated under the induction of cellulose, which was consistent with the changes in extracellular β-glucosidase activity. Studies have suggested that the GH3 gene family in Xylaria plays an important role in cellulose degradation and plant pathogenicity. Glycosylation is an important post-translational modification of proteins, which can affect the solubility, stability and catalytic activity of proteins, and also has important biological functions related to protein folding, localization and translocation. In recent years, a growing number of studies have demonstrated that glycosyltransferases are closely related to pathogenic virulence and play key roles in biological processes such as the adhesion, immune escape and colonization of pathogenic bacteria. The gene encoding GT2 of the glycosyltransferase family in T. polysporum HZ-31 was annotated, and GT2 was shown to be involved not only in biomass synthesis, but also in many complex aspects of cellular processes in fungi. Zhang et al. [ 23 ] used CRISPR/Cas9 and homologous recombination techniques involving deletion and backfilling of the PaGt2 gene of the GT2 family encoding glycosyltransferase, and found that the strain was significantly inhibited in nutrient growth, did not produce conidiophores and conidia, and had significantly reduced pathogenicity on peach shoots and fruits. Genomics, molecular biological and bioinformatics studies have shown that the genes encoding enzymes which produce various fungal secondary metabolites are clustered and often in close proximity to telomeres [ 24 ] . The genes that are found in clusters of secondary metabolite synthesis genes are frequently co-regulated according to the functions of the secondary metabolites encoded by these genes [ 25 ] . Furthermore, an increasing number of secondary metabolite synthesis genes are thought to be closely related to, or even regulate, the pathogenicity of pathogenic bacteria. In this study, the T. polysporum HZ-31 secondary metabolite synthesis gene cluster was annotated to genes that synthesize toxins such as enniatin, beauvericin and Mellein. Beauvericin is a non-specific phytotoxin with toxic effects on many cell lines, and the essential components in its synthesis are the amino acids L-Phe, D-HYIV, ATP/Mg + and ADOMet [ 26 ] . The mechanism of its cytotoxicity involves its role as a K + ion carrier, in which it can be embedded in biological membranes, forming channels, triggering the elevation of Ca 2+ in the cytoplasm, affecting the electrochemical gradient of the cell membrane, and ultimately inducing a series of cytotoxic reactions. Beauvericin can also enter the nucleus of plant cells, combine with DNA to form DNA-BEA complexes, and through calcium-dependent endonuclease cleavage of the bound DNA, it can interrupt chromosomes and cause toxicity. Chen [ 27 ] found that knockdown of the leukocidin homologous gene FOXB_16250 in Fusarium spinosum Fo5176 resulted in a reduction in the pathogenicity of the Fo5176 mutant, as well as a delay in the onset of disease in the mutant inoculated into Columbia-type Arabidopsis thaliana wild-type plants, suggesting that leukocidin synthesis genes inhibit Fusarium spinosum pathogenicity. Enniatin is a hexapeptide fungal toxin that is present in the mycelium and can have a strong toxic effect on the cellular tissues of plants [28]. The esyn1 gene is an important regulator of the biosynthesis of enniatin. Chen et al. [ 29 ] cloned the esyn1 gene from Foc4, and compared with the wild strain, the biosynthesis of Fusarium enantiospirillum was significantly reduced in the knockout mutant. Furthermore, the pathogenicity of the mutant was completely lost, whereas backfilling of the wild strain was able to restore the biosynthesis and pathogenicity of Fusarium enantiospirillum , which suggests that this gene is a key factor in the pathogenic bacterial infections of the plant. Mellein is a known compound with various phytotoxic, cytotoxic, fungicidal, antimicrobial and larvicidal activities reported [ 30 ] . Li et al. [ 31 ] demonstrated the presence of (R)-(-)-mellein in the fermentation broth of Vitis vinifera and found that it was also present in Vitis vinifera -infected apple fruits and twigs, and that there was a relationship between lesion expansion and honey curdling mycorrhizal fungal pigmentation in the apple tissues. Phytotoxicity bioassays have shown that honeystrobin causes discoloration and death of apple leaves and browning of stems. Another study showed that the main components of the toxin of Sphaeropsis sapinea , a pine tree dieback disease, are also the above two forms of R-(-)-Mellein and 4-hydroxyMellein, in which R-(-)-Mellein plays a major role, while the other two are synergistic with each other in the toxin and antifungal activity assays [ 32 ] . These secondary metabolites play a key role in the pathogenicity of pathogens in their host plants, and the gene clusters that regulate the synthesis of secondary metabolites are fundamental in the regulation of that pathogenicity. The gene clusters of secondary metabolite synthesis annotated in the present study may also play important roles in the pathogenicity of T. polysporum HZ-31 in weeds. By sequencing the whole genome of the T. polysporum HZ-31 strain, all the genetic information for the genome of this pathogen was obtained. Many virulence-related pathogenic genes were found, which were mainly involved in cell wall catabolic enzymes, strain nutrient growth and biomass synthesis, etc. The genome information also showed that T. polysporum HZ-31 contains a large number of genes involved in toxin biosynthesis, suggesting that T. polysporum HZ-31 is able to produce a variety of toxins during the infestation process. The present study bridges the gap in the genomic information of this strain, and also provides the necessary genetic background information for further analyzing the herbicidal mechanism of this strain.

This region also has special ecological characteristics such as high altitude, severe cold, strong radiation, and drought \u003csup\u003e[2]\u003c/sup\u003e, resulting in a very low environmental carrying capacity\u003csup\u003e\u0026nbsp;[3]\u003c/sup\u003e, and the ecological environment is extremely fragile and vulnerable to damage. The extensive use of chemical herbicides has made the Tibetan Plateau region prone to ecological pollution, weed resistance and other problems. Reducing the amount of chemical herbicides used in response to the special ecological conditions of the region can effectively reduce the pollution of the ecological environment and increase crop yields. Microorganisms and their metabolites have herbicidal activity, and they have received more attention in the field of biocontrol research in recent years \u003csup\u003e[4]\u003c/sup\u003e.

These secondary metabolites play a key role in the pathogenicity of pathogens in their host plants, and the gene clusters that regulate the synthesis of secondary metabolites are fundamental in the regulation of that pathogenicity. The gene clusters of secondary metabolite synthesis annotated in the present study may also play important roles in the pathogenicity of \u003cem\u003eT. polysporum\u003c/em\u003e HZ-31 in weeds.\u003c/p\u003e \u003cp\u003eBy sequencing the whole genome of the \u003cem\u003eT. polysporum\u003c/em\u003e HZ-31 strain, all the genetic information for the genome of this pathogen was obtained. Many virulence-related pathogenic genes were found, which were mainly involved in cell wall catabolic enzymes, strain nutrient growth and biomass synthesis, etc. The genome information also showed that \u003cem\u003eT. polysporum\u003c/em\u003e HZ-31 contains a large number of genes involved in toxin biosynthesis, suggesting that \u003cem\u003eT. polysporum\u003c/em\u003e HZ-31 is able to produce a variety of toxins during the infestation process. The present study bridges the gap in the genomic information of this strain, and also provides the necessary genetic background information for further analyzing the herbicidal mechanism of this strain.\u003c/p\u003e"},{"header":"Declarations","content":"\u003ch2\u003eConflict of interest\u003c/h2\u003e \u003cp\u003eThe authors declare no conflict of interest.\u003c/p\u003e \u003ch2\u003eContributions\u003c/h2\u003e \u003cp\u003eYushan He and Haixia Zhu conceived the study, collected samples, and did lab steps.

The raw data were cleaned up using Trimmomatic and checked for quality using FastQC. The sequencing data were assembled using SPAdes, and GeneMark was used to perform gene prediction on the assembly results. The results showed that the genome size of \u003cem\u003eT. polysporum\u003c/em\u003e HZ-31 was 39,325,746 bp, with 48% GC content, and the number of genes encoded was 11,998. A total of 148 tRNAs and 45 rRNAs were predicted. A total of 782 genes were annotated in the Carbohydrase Database, 757 genes were annotated to the Pathogen-Host Interaction Database, and 67 gene clusters were identified. In addition, 1023 genes were predicted to be signal peptide proteins. The annotation and functional analysis of the whole genome sequence of \u003cem\u003eT. polymorpha\u003c/em\u003e HZ-31 provide a basis for the in-depth study of the molecular mechanism of its herbicidal action and more effective utilization for weed control.\u003c/p\u003e","manuscriptTitle":"Whole genome sequencing and analysis of the weed pathogen Trichoderma polysporum HZ-31","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2024-04-09 10:56:13","doi":"10.21203/rs.3.rs-4124222/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Revision requested","date":"2024-04-29T08:26:07+00:00","index":"","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2024-04-25T07:48:49+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2024-04-19T16:07:48+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"a39640d5-7062-47f1-acbb-e8f6f5d6af6b","date":"2024-04-11T08:11:27+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"84cac099-c70d-4f66-8010-ba9968f725ef","date":"2024-04-10T13:38:09+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2024-04-10T06:44:15+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2024-04-10T06:42:43+00:00","index":"","fulltext":""},{"type":"editorInvited","content":"","date":"2024-04-09T11:20:59+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2024-04-04T07:47:45+00:00","index":"","fulltext":""},{"type":"submitted","content":"Scientific Reports","date":"2024-03-18T14:57:56+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"
