The utility model relates to the technical field of gibberella fermentation, in particular to a waste residue treatment device for gibberella fermentation, which comprises a support table, an outer cylinder is mounted at the top of the support table in a penetrating manner, a cover plate is placed at the top of the outer cylinder, a support frame is connected to the center of the top of the cover plate, and a variable frequency motor is mounted on the support frame in a penetrating manner. The output end of the variable frequency motor and the interior of the outer cylinder are jointly connected with a processing part. According to the utility model, the variable frequency motor runs slowly, and meanwhile, the telescopic end of the electric telescopic rod II extends out to further open the electromagnetic valve on the discharge pipe; when the telescopic end of the second electric telescopic rod corresponds to the arc-shaped notch, the follow-up variable frequency motor runs at a high speed, so that liquid in the gibberella fermentation waste residues is thrown out and discharged from the discharging pipe. The gibberellic acid fermentation waste residues are crushed by the main heating crushing rod and the auxiliary heating crushing rod, and the gibberellic acid fermentation waste residues are dried by the heating column, the main heating crushing rod and the auxiliary heating crushing rod.

The invention belongs to the technical field of crop variety innovation, and particularly relates to a breeding method and application of wheat capable of resisting gibberellic disease and herbicide-tolerant starter propagation. According to the method disclosed by the invention, through combination of molecular marker-assisted selection and backcross breeding, excellent characters from different donors are rapidly introduced into a genetic background of an excellent koji-making variety, so that accurate and efficient polymerization of target characters is realized, and the screening efficiency and accuracy can be improved; meanwhile, the screening index of starter propagation quality runs through the breeding process, so that the bred material is not only excellent in resistance and agronomic character, but also can meet the specific requirements of the terminal industry. The variety bred by the method provided by the invention can reduce the use of pesticides for preventing and treating gibberellic disease and reduce the pollution risk of fungaltoxin; the herbicide-resistant characteristic facilitates field weed management, and the yield and quality stability are improved; the special quality guarantees the high additional value in the starter propagation industry, and creates the value of the whole industrial chain from the field to the workshop.

This invention discloses molecular markers, primers, and their applications closely linked to the major quantitative trait locus for wheat resistance to Fusarium head blight (Fusarium head blight) Qfhb.jaas-7DS, belonging to the field of agricultural biotechnology. This invention identifies a novel, stable major quantitative trait locus (QTL) for Fusarium head blight resistance on the short arm of chromosome 7D, named Qfhb.jaas-7DS. To effectively utilize this resistance locus, two KASP markers, KASP-109827800 and KASP-109891380, closely linked to this locus, were designed and developed based on the 7D chromosome genome sequence and SNP sequence information. These two markers serve as molecular markers for the Fusarium head blight resistance gene on the short arm of wheat chromosome 7D, and can be used for high-throughput detection of this locus, as well as assisted selection of Fusarium head blight resistant wheat varieties carrying this gene, thereby accelerating the breeding process of disease-resistant varieties.

The invention provides an engineering bacterium for high-yield gibberellic acid GA3 as well as a construction method and application thereof, and belongs to the technical field of gene engineering. According to the invention, gibberella fujikouensis QJ47-9 is used as an original strain, and a DES gene overexpressed strain marked as a DESOE strain is obtained by overexpressing and amplifying a gene DES encoding DES dehydrogenase. On the basis of the DESOE strain, the P450-3 monooxygenase is subjected to key amino acid mutation, the selected mutation sites are F97Y, T220A, V236I and D350Q, and the mutant strain is marked as DESOE / p450-3 delta. After fermentation culture is carried out for 7 days at the temperature of 28 DEG C and the speed of 250 rpm, the yield of GA3 is increased to 2.51 g / L from 1.53 g / L of an initial strain, and the increasing rate is 64.05%; meanwhile, the yield of a byproduct GA1 is reduced to 0.06 g / L.
