Background
Fusarium sp is a kind of worldwide distributed fungus, which can not only live through winter and summer in soil, but also infect various plants (grain crops, economic crops, medicinal plants and ornamental plants), causing various diseases of root rot, stem-base rot, flower rot, ear rot and the like of the plants, wherein more than 100 host plants infect host plant vascular bundle systems, destroy the vascular bundles of the transport and guide tissues of the plants, generate toxins in the processes of growth, development and metabolism to harm the crops, cause crop wilting and death, influence yield and quality, and is one of the most difficult important diseases for production control. Fusarium infected plants or seeds contain various mycotoxins, mainly including trichothecenes (CTCs), zearalenone (zearalenone), butenolide (butenolide), fumonisin (fumonisins fb) and other toxins.
Diseases caused by infection of cereals by fusarium graminearum (mainly including f.asiticum, f.graminearum Schwabe and f.pseudograminearum) mainly include scab and stem rot of wheat, barley, oats, corn and millet. Currently, wheat, barley and corn gibberella are serious fungal diseases which are difficult to solve worldwide. For example, the crop yield reduction and mycotoxin contamination of grains caused by wheat scab become one of the most urgent food safety problems to be solved in China and worldwide. Fusarium graminearum infects wheat spikes in the populus florescence of wheat and secretes a large amount of trichothecene toxins, so that the pathogenicity of pathogenic bacteria is obviously increased, and the destructive damage to the yield is caused. Meanwhile, after eating wheat grains polluted by the toxins, the appetite loss or abolition, gastrointestinal inflammation and bleeding, vomiting, diarrhea, necrotizing dermatitis, dyskinesia, poor blood coagulation, anemia, reduction of the number of white blood cells, reduction of immune functions, abortion and the like can be caused, and the health of people and livestock is seriously threatened.

Shaking for 10s, performing ultrasonic treatment at room temperature for 30min, collecting supernatant, and transferring to a new centrifuge tube. Vacuum concentrating to dry powder. Before injection, 100 μ L20% acetonitrile was used for resuspension, and after filtration through a 0.22 μm filter, the sample was transferred to a sample vial for LC-HRMS detection.
9. The experimental results are as follows:
to identify the biochemical and biological effects of ThFhb7 in wheat, T was first overexpressed in wheat driven by the maize ubiquitin promoter3The generation homozygous transgenic wheat head is inoculated with fusarium graminearum. In the wheat flowering period, fusarium graminearum is inoculated for 72 hours, and then sampling is carried out for detection. As shown in FIG. 1, DON-GSH adduct, M/z 604.21730 (corresponding to [ M + H ] 604.21730, was detected from Fg-infected ThFhb7 wheat in positive ion mode of LC-HRMS (full scan)]+Δ ± 5 ppm); NIV-GSH adduct, M/z 620.21199 (corresponding to [ M + H ] was detected in Fg-infected ThFhb7 wheat]+, Δ. + -. 5 ppm). Whereas in the corresponding control (fusarium graminearum infected wheat transgenic recipient material) no corresponding GSH adduct production was detected.
As 3-ADON and 15-ADON are isomers with the same molecular weight, and a Full scan mode first-order spectrum cannot be distinguished, the LC-HRMS (/ MS) positive ion PRM mode is selected for detection, and the detection result is shown in figure 2. With the parent ion M/z 646.22764 (corresponding to [ M + H ]]+Δ ± 5ppm), daughter ion m/z 321.11210 detected 3-ADON-GSH adduct from Fg infected ThFhb7 wheat; with the parent ion M/z 646.22764 (corresponding to [ M + H ]]+Δ ± 5ppm), the daughter ion m/z 450.15471 detected 15-ADON-GSH adduct from Fg infected ThFhb7 wheat. Whereas no corresponding GSH adduct production was detected in the corresponding control wheat transgene receptor fielder.
And (4) conclusion: single fusarium graminearum strains can generate trichothecene toxins when infecting wheat ears in the flowering period within 72 hours, DON, 3-ADON, 15-ADON and a small amount of NIV are definitely detected by LC-HRMS in the experiment, but other toxins such as T2, HT-2 and the like are not detected due to extremely low content. The experimental results show that: when fusarium graminearum infects transgenic wheat over-expressing ThFhb7, DON, 3-ADON, 15-ADON and NIV can be efficiently catalyzed into glutathione adduct. The transgenic ThFhb7 wheat improves the toxin resistance, proves that ThFhb7 can take trichothecene toxins as substrates and catalyze the trichothecene toxins into corresponding GSH adducts, and can improve the gibberellic disease resistance of wheat.
Second, quantitative detection of toxin in transgenic wheat and its derivative
In view of the above, it was demonstrated that ThFhb7 can catalyze toxins such as DON, 3ADON, 15ADON, NIV, etc. to GSH form derivatives in wheat in the case of fusarium graminearum infection. To further demonstrate the content variation of these toxins, the toxins were further quantified using a high-resolution liquid LC-HRMS (/ MS) PRM profile. Because the PRM mode has higher requirements on the toxin content, the experiment only carries out related quantitative detection on DON and 3ADON in transgenic wheat which excessively expresses ThFhb7, and the specific result is shown in figure 3.
Inoculating fusarium graminearum to the ThFhb7 wheat head, taking materials at different time points, and then measuring the contents of DON, DON-GSH, 3-ADON and 3-DON-GSH. FIG. 3(a) shows that transgenic wheat containing ThFhb7 specifically catalyzes the formation of DON-GSH, whereas the control material JW1 without ThFhb7 does not detect accumulation of DON-GSH. The results in FIG. 3(b) show that after inoculation with Fg, substrate DON is significantly reduced relative to wheat without ThFhb7 (about 1/3) due to the fact that DON-GSH is synthesized in large quantities in the presence of ThFhb 7. Similarly, FIG. 3(c) transgenic wheat containing ThFhb7 can synthesize 3-ADON-GSH, while control material JW without ThFhb713-ADON-GSH (green) is not detected. Figure 3(d) wheat with ThFhb7 was significantly less (about 1/3) than control recipient material 3-ADON without ThFhb7 after spike inoculation with Fg. The experiment proves that ThFhb7 can efficiently derive DON and 3-ADON to generate DON-GSH after wheat is infected by fusarium graminearum, so that accumulation of DON toxin in wheat bodies is reduced, and the detoxification effect is achieved.
The quantitative detection results of the toxin and the derivatives thereof show that the fusarium graminearum infected wheat can generate a large amount of DON and 3-ADON. The results of quantification of PRM show that: when F.g infects wheat with trans-gibberellic disease resistance gene ThFhb7, the content of DON and 3-ADON is reduced by about 2/3 compared with the control, and the DON-GSH and 3-ADON-GSH are correspondingly increased along with the reduction of DON and 3-ADON. The ThFhb7 transgenic wheat improves the toxin resistance, and proves that ThFhb7 can catalyze the wheat into a corresponding GSH adduct by using DON and 3-ADON as substrates and can play a role in vivo detoxification.
Third, transgenic wheat scab resistant phenotype and statistical data
On the basis of toxin analysis after the transgenic wheat is infected by fusarium graminearum, disease resistance investigation is carried out on the transgenic wheat. Comprises an overexpression transgenic line forcibly expressed under a ubiquitin promoter, wherein the receptor material is wheat variety fielder; and the original expression transgenic line generated by transforming the original promoter of ThFhb7 donor material in wheat variety Kenong 199, and performing related disease resistance investigation.
The fusarium graminearum spore suspension is prepared by the method, and the concentration is adjusted to 2 multiplied by 105one/mL, 10. mu.l of spore suspension was inoculated onto the upper middle part of the ear while bagging and moisturizing. When the spores germinate on the spikelets and obvious hyphae can be seen, the bags are removed. Inoculating about 30 spikes to each strain, observing the disease condition, counting the number of small pathogenic spikes after 21d of inoculation, and performing differential analysis. The results are shown in fig. 4, where both the overexpressed and originally expressed transgenic lines were found to have significantly smaller numbers of diseased spikelets than the control recipient material.
And (4) conclusion: the overexpression vector and the original expression vector of the ThFhb7 gene are constructed. Transferring the two vectors into corresponding wheat receptors to obtain T0Strictly self-pollinating the ThFhb7 high-expression wheat line to T by PCR and RT-PCR screening3. The scab resistant spike of the positive transgenic line is identified by using a single flower instillation method, and the morbidity spikelet number of the over-expression transgenic line and the morbidity spikelet number of the original expression transgenic line are obviously lower than that of a control receptor material. The experimental results show that the expression of ThFhb7 can obviously improve the gibberellic disease resistance of wheat.

Identifying the extensive resistance of Fusarium strain by using in-vitro leaf Fhb transgenic strain, culturing seedlings to two leaves and one heart to three leaves and one heart, selecting the same leaf position, and dividing the leaf into 3-3.5cm leaf segments, wherein the fracture of the leaf segment is required to be neat without causing the damage of mesophyll tissues, a round wound is made at the middle position of the upper surface of the leaf segment by using a liquid transfer device wall head, and the round wound is inoculated with 2.5 mu L of 2 multiplied by 10 mu L of liquid transfer agent with the concentration of 2 multiplied by 105Each/mL of different Fusarium spore suspensions, 24 replicates per strain, were cultured at 25 ℃ under humidified conditions for 3 days and the spread of lesions observed. Fusarium graminearum and Fusarium asia are the two major strains responsible for head blight. Fusarium pseudograminearum is the predominant strain responsible for the stalk rot of wheat. First, a round wound was made in the center of the excised leaf of a two-leaf one-heart seedling by using a pipette tip, and 2. mu.L of a Fusarium conidia suspension was inoculated at the wound site and moisturized at 25 ℃ for 3 days. Then theThe area of necrotic spots was measured for fusarium resistance assessment. As a result, as shown in FIGS. 5(a), 5(b) and 5(c), the ThFhb7 transgenic plant showed a significant reduction in the lesion area of the leaf compared to the susceptible control family of agricultural 199 inoculated with spore suspensions of three species, Fusarium graminearum, Fusarium asia and Fusarium pseudograminearum.
3.2 Stem root rot resistance results
The results of inoculating the recipient material and the ThFhb7 transgenic material with a Fusarium graminearum conidium suspension 15d using the method of shoot base wound inoculation are shown in FIG. 6(a), and indicate that the incidence of transgenic wheat shoot base is reduced compared to the control. The results in FIG. 6(b), (c) show that the mortality rate of the plants with the ThFhb7 gene is significantly lower than that of the wild type. Pseudograminearum is a dominant species responsible for the stem rot of wheat. In FIG. 6(a), the stalk base rot disease was observed by making a round wound at the base of the stalk of a four-leaf single-heart wheat seedling with a pipette tip, inoculating 2. mu.L of a Fusarium conidium suspension at the wound site, and moisturizing the wound for 15 days at 25 ℃. FIG. 6(b) is a graph showing the statistical analysis of mortality and the differential analysis after 15 days of illness at 25 ℃.
And (4) conclusion: the extensive resistance of the ThFhb7 transgenic strain to Fusarium species is identified by utilizing the ThFhb7 transgenic strain and the excised leaf of the recipient material farm 199, and the result shows that the scab areas of the three strains, namely the Fusarium graminearum, the Fusarium asianum and the Fusarium pseudograminearum, on the leaf are all obviously smaller than those of an infectious control, which indicates that the ThFhb7 has a relatively broad-spectrum resistance to the Fusarium; among them, Fusarium pseudograminearum is the dominant species responsible for the stem rot of wheat. In addition, the experiment proves that the short-fragment translocation line material R-JM22 containing ThFhb7 and the ThFhb7 gene strain which are taken as the background by JM22 are inoculated with Fusarium graminearum to identify the wheat stem basal rot resistance of the two materials, the result is consistent with the leaf phenotype, and the two materials show good wheat stem basal rot resistance, which indicates that ThFhb7 can improve the resistance of wheat to the stem basal rot.

TILLING assay
3.1PCR amplification
Since the full length of the gene was 864bp, we sequenced the full length of the gene and screened for mutants using a traditional Sanger sequencing platform. Full-length primer of ThFhb7
F：5'-TTCATCATCCTGCTAGGCGATAAGA-3'
R：5'-CTACTTCACCTCGGGGCATACTTGTC-3'
We used UNG enzyme treatment in combination with targeted preamplification using dUTP, in which deoxythymidine triphosphate (dTTP) was replaced with deoxyuridine triphosphate (dUTP). Prior to initiation of PCR, any uracil-containing PCR products will be degraded, i.e., residual contaminants will be eliminated, using uracil DNA N-glycosylase (UNG). PCR amplification was performed in a total volume reaction of 10. mu.l, containing 1 × Multiplex PCR Mastermix (UNG) (CWBIO Bio, China), 0.7. mu.M of each primer and 100ng of template DNA. The amplification curve included 1 cycle at 50 ℃ for 2-8 minutes and 5 minutes at 95 ℃ followed by 35 cycles of 30s at 94 ℃, 30s at 60 ℃ and 50s at 72 ℃ and finally 10 minutes at 72 ℃. The homozygous and heterozygous status of each point mutation was verified by manual inspection of the signal peak maps by DNAMAN. Homozygous mutants were screened for further phenotypic characterization of FHB resistance.
3.2 phenotypic identification of resistance to gibberellic disease
Culturing the selected homozygous mutant plant until two leaves and one heart to three leaves and one heart, selecting the part with flat leaves and consistent width, dividing the part into 3-3.5cm leaf segments, requiring the leaf segment to have regular fracture without causing mesophyll tissue damage, making a round wound at the middle position of the upper surface of the leaf segment, inoculating 1-2.5 μ L of the round wound with concentration of 2 × 105Each mutant was replicated 10 times in each of the fusarium graminearum spore suspensions at 25 ℃ under humid conditions for 3 days, and the spread of lesions was observed.
4. Results of the experiment
4.1 mutant screening
The about 4000M2 mutant was screened for mutations by direct sequencing (Sanger) of the full-length PCR product of ThFhb7 (primers as before). To avoid possible template contamination during PCR, deoxyuridine triphosphate (dUTP) was used in place of deoxythymidine triphosphate (dTTP) in PCR, and uracil DNA N-glycosylase (UNG) treatment was performed to degrade any uracil-containing PCR product in the template. The final screen yielded 24 amino acid variants with partial alignment shown in FIG. 8.
4.2 phenotypic identification of mutant scab resistance
The phenotypic identification of mutants against gibberellic disease is shown in FIG. 9, where the wheat lines containing ThFhb7 were subjected to EMS mutagenesis. By using excised leaves for scab resistance assessment, a total of 7 mutants with amino acid changes in the CDS region were significantly different from the disease-resistant control. The area of necrotic spots 3 days after inoculation was counted and at least 10 leaves ex vivo were used for each sample.
Through the combination of UNG enzyme treatment and targeted pre-amplification using dUTP, residual contamination and false positive methods are eliminated, and finally 24 mutants are obtained through screening. The resistance to gibberellic disease was assessed by using leaves ex vivo, 5 missense mutations, 2 stop mutations out of 7 significantly different mutants of the ThFhb7 gene from the disease-resistant control; although the disease susceptibility of the 7 mutants is different, the lesion areas are all significantly larger than those of the disease-resistant control (statistics of the area of the necrotic spots of the mutants in FIG. 9). Functional analysis showed that the proto-decyloxy activity was retained to varying degrees in each of the 24 mutants. Wherein the stop mutation is located at the C-terminus of ThFhb7, and ends at amino acids 209 and 243, respectively, but both ends do not result in complete loss of function of the enzyme. Thus, it was shown that the functional domain of the enzyme is mainly N-terminal. In addition, the 5 missense mutations at 34, 48, 98, 99 and 106 in the mutant had a greater effect on the activity of the de-epoxy group. Therefore, it can be regarded as a key amino acid.
