Ustilaginoidea virens, perfect sexual stage Villosiclava virens, is a plant pathogen which causes the disease False Smut of rice which reduces both grain yield and grain quality. The disease occurs in more than 40 countries, especially in the rice producing countries of Asia. but also in the U.S. As the common name suggests, it is not a true smut (fungus), but an ascomycete. False smut does not replace all or part of the kernel with a mass of black spores, rather sori form erupting through the palea and lemma forming a ball of mycelia, the outermost layers are spore-producing. Infected rice kernels are always destroyed by the disease.

Construction of the spatiotemporal interaction pattern between dominant strain of ustilaginoidea virens heb07 and the pathogen of wheat sharp eyespot
The application discloses a Ustilaginoidea virens dominant strain HEB07 and construction of a Ustilaginoidea virens pathogenic bacterium and millet interaction space-time atlas, relates to the technical field of biology, and the strain is screened and verified, the strain has the infection breadth of different millet varieties and the infection pathogenic sensitivity and survival rate of any millet variety, and has high affinity of recombination transformation of a GFP fluorescent label, so as to constitute a gene recombination strain using a green fluorescent protein GFP and explore the Ustilaginoidea virens pathogenic bacterium and millet interaction dominant strain. The application can provide important technical support for cloning research of millet disease-resistant genes, and provide strong scientific basis and technical means for cultivating millet varieties with high resistance to Ustilaginoidea virens.
