This invention discloses a strain of Acanthamoeba that inhibits the pathogen of Fusarium graminearum and its applications. Acanthamoeba (Acanthamoeba rhysodes NJAU-ZY1, deposited at the China Center for Type Culture Collection (CCTCC) with accession number CCTCC NO: C2025219, demonstrates in plate experiments, liquid co-culture experiments, and pot experiments that inoculation with the protozoan Acanthamoeba NJAU-ZY1 significantly inhibits the growth of Fusarium graminearum pathogen, reduces its infectivity in wheat, alleviates the inhibitory effect of Fusarium graminearum on wheat growth, reduces the risk of diseases caused by this pathogen, and thus increases wheat biomass. This provides a new strategy and resource for the biological control of Fusarium graminearum pathogen and the scientific cultivation of wheat, and has important application value for the safe production of food crops.

The application discloses a set of detection wheat relative species universal markers and application thereof, and belongs to the technical field of plant genetic engineering. The application takes different species of triticeae as research objects, selects specific primers designed on the basis of the length polymorphism information of different introns of the conserved genes of triticeae identified by using the existing Chinese spring wheat reference genome and annotation information and a bioinformatics method, and finally develops the polymorphic DNA molecular markers capable of distinguishing different ploidy materials of triticeae by using PCR technology and agarose gel electrophoresis technology. The molecular markers have high specificity, stability and universality, and provide a new direction for identification of exogenous chromosome fragments of wheat, molecular marker assisted breeding of exogenous genes and screening of germplasm resources.

The invention discloses an acanthamoeba protozoa for inhibiting fusarium graminearum pathogenic bacteria and application of the acanthamoeba protozoa. The acanthamoeba rhysodes NJAU-ZY1 is preserved in the China Center for Type Culture Collection, and the preservation number of the acanthamoeba rhysodes NJAU-ZY1 is CCTCC (China Center for Type Culture Collection) NO: C2025219. Results of a plate experiment, a liquid co-culture experiment and a pot experiment show that inoculation of the protozoa acanthamoeba NJAU-ZY1 can significantly inhibit the growth of the fusarium graminearum pathogenic bacteria and reduce the infection ability of the fusarium graminearum pathogenic bacteria on wheat, so that the inhibition effect of the fusarium graminearum pathogenic bacteria on the growth of the wheat is relieved, and the growth of the wheat is inhibited. The disease risk caused by the pathogenic bacteria is reduced, so that the wheat biomass is improved, a new strategy and a new resource are provided for biological prevention and control of the fusarium graminearum pathogenic bacteria and scientific wheat planting, and the method has an important application value for safe production of food crops.

It was found that the flowering ability of a Triticeae plant could be improved by suppressing the function of the Sof1 gene, and that the flowering ability of a Triticeae plant can be evaluated based on suppression of the function of the Sof1 gene. A method for producing a a Triticeae plant with improved flowering ability and a method for improving flowering ability of a Triticeae plant are also disclosed.

The present invention relates to isolated polynucleotides encoding proteins which, when expressed in a Triticeae plant cell, particularly wheat plant cells, enhance tolerance and / or confer resistance towards stem rust disease, and to Triticeae plants comprising the polynucleotides that are tolerant or resistant to the stem rust diseases, as well as to methods of producing same and of identifying resistant plants.

A portable wheat plant-row seeding device belongs to the technical field of agricultural machinery and comprises a frame, a conveying unit and a power unit, the frame is composed of a transverse support, a vertical frame and a bottom frame, and the stability of the device is ensured. The conveying unit is composed of a seed feeding opening, a seed blocking cylinder, a seed dividing head, a rotating shaft, a hose, a seed dividing grid, a seed dividing grid disc and a conveying cover, and the seed feeding opening, the seed blocking cylinder, the seed dividing head, the rotating shaft and the hose work cooperatively to achieve automatic distribution and uniform sowing of seeds. The power unit is composed of a power source and a seed throwing motor, power is transmitted to the opposite conveying unit through the power unit, the seed dividing head rotates to generate centrifugal force, and finally seeds can be evenly sown into a breeding field. Through the design of the seed blocking cylinder and the seed dividing lattice disc which are in clearance fit, cleaning and maintenance are convenient, and continuity and uniformity of seeding are ensured. The utility model is suitable for wheat scientific research breeding units, provides an efficient and uniform seeding tool, obviously reduces the labor intensity of breeders, and improves the breeding efficiency.

The present invention relates to polynucleotides which, when expressed in a Triticeae plant cell, particularly wheat, barley or rye plant cells confer or enhance resistance or tolerance towards leaf rust disease and / or stripe rust disease, and to Triticeae plants comprising the polynucleotides that are tolerant or resistant to the rust diseases, as well as to methods of producing same and of identifying resistant plants.
