The invention relates to a mycorrhizal cultivation method for improving the stress resistance of pinus khasys seedlings, and belongs to the technical field of agricultural planting, the cultivation method comprises the following steps: (1) compounding fibrous belly fungi, bolete and russule virens into a microbial inoculum, and culturing to prepare microcapsules; (2) taking turf, vermiculite, humus soil and perlite as substrates, and adding a microcystis agent and a water-retaining agent; (3) the seeds are disinfected and sown, and seedlings are domesticated through light intensity gradient, water stress and temperature fluctuation; 4, during transplanting, abscisic acid is used for treating root systems, organic fertilizer is pre-filled, and mycorrhizal activation promoting liquid is perfused, through the synergistic effect of composite mycorrhizal fungi and stress domestication, the stress resistance, the survival rate and the afforestation adaptability of pinus khasys seedlings are remarkably improved.

This invention relates to the field of genetic engineering technology, and provides a ZmPHYLL gene, the full-length nucleotide sequence of which is shown in SEQ ID NO: 1, and the coding region nucleotide sequence of which is shown in SEQ ID NO: 2. This invention also provides the application of the above-mentioned ZmPHYLL gene in inhibiting the germination of *Russula multifiliis* spores and improving the resistance of maize plants to southern maize rust. Simultaneously, this invention provides a method for improving the resistance of maize plants to southern maize rust. In this study, a ZmPHYLL gene was screened, and the expressed protein of this gene can effectively inhibit the germination of *Russula multifiliis* spores. Therefore, by regulating the overexpression of this gene, the resistance of maize to southern maize rust can be improved. This invention provides new gene resources for the creation of breeding materials and provides important scientific basis for the breeding of maize varieties highly resistant to southern maize rust.

The present application belongs to the field of edible fungi, and particularly relates to a new species of Russula and application thereof. Pseudolagarobasidium acaciicola The taxonomic name of the new species of Russula is Pseudoguignardia sp., which has been registered and preserved in the Guangdong Microbial Culture Collection Center on April 24, 2022, and the preservation number is GDMCC No. 62414. The new species of Russula GDMCC No. 62414 provided in the present application can be artificially cultivated, and has the characteristics of large number of fruiting bodies, high yield, good mushroom shape and the like, and is a new species of Russula with great development potential.

The application relates to a mycorrhizal cultivation method for improving the stress resistance of Pinus kesiya var. thurberi seedlings, and belongs to the technical field of agricultural planting. The cultivation method comprises the following steps: (1) compounding Rhizopogon fulvum, Boletus and Russula variabilis to form a fungicide, and preparing microcapsules after culture; (2) taking grass carbon, vermiculite, humus soil and perlite as a matrix, and adding the microcapsule fungicide and a water-retaining agent; (3) disinfecting and sowing seeds, and domesticating seedlings through light intensity gradient, water stress and temperature fluctuation; and (4) treating the root system with abscisic acid when transplanting, pre-filling organic fertilizer and pouring mycorrhizal promoting activation liquid. The application significantly improves the stress resistance, survival rate and afforestation adaptability of Pinus kesiya var. thurberi seedlings through the synergistic effect of composite mycorrhizal fungi and stress domestication.

The application belongs to the polymer field and discloses application of a nanocellulose / chitosan active packaging film in preservation of Russula, wherein the nanocellulose / chitosan active packaging film is prepared by mixing Ag@MOF carriers loaded with natural antibacterial agent natal oil and nanocellulose / chitosan compound, and the obtained product has good tensile strength, elongation at break and water vapor permeability, and shows good film ductility and gas barrier performance; the packaging film is applied to Russula packaging, can effectively inhibit the growth of specific spoilage bacteria such as Pseudomonas, Serratia and Penicillium during the storage of Russula, so as to achieve the purpose of preserving Russula, and can slowly release the natal oil, thereby prolonging the preservation period of Russula.

The invention relates to a method and a kit for rapidly identifying russula vinosa, and belongs to the technical field of detection methods. A fresh mushroom sample is prepared into a mushroom extracting solution, and the mushroom extracting solution is subjected to vortex, drying and centrifugation to obtain supernate; adding an N-methyl phenylethylamine solution, a triphenylphosphine solution and a 2, 2 '-dithiobipyridine solution into the supernate, and carrying out derivatization reaction to obtain a primary derivatization sample solution; a magnesium monoperoxyphthalate hexahydrate solution is added for a derivatization reaction, and then a NaHCO3 solution is added for a secondary derivatization reaction; and performing LC-MS / MS analysis on the primary derivatization sample solution and the secondary derivatization sample solution to identify whether a derivatization product of cyclopropyl-2-alkene carboxylic acid exists or not. The method is short in required time, mild in condition and good in specificity.
