The application discloses a sequence of Medicago truncatula AP2 / ERF transcription factor ERM1 and application of the sequence in improving mycorrhizal colonization efficiency of leguminous plants and promoting mycorrhizal symbiosis, and relates to the technical field of plant genetic engineering. ERM1 The gene has a significant promoting effect on the symbiosis of alfalfa and arbuscular mycorrhizal fungi, and the application has important significance for clarifying the biological function of ERM1 in the symbiosis of leguminous plants and mycorrhizal fungi, thereby regulating the symbiosis between plants and mycorrhizal fungi, and provides a research foundation and scientific basis for improving the symbiosis efficiency of leguminous crops by using biological strengthening means.

The present application relates to the field of biological agriculture, and in particular to the application of the gene MtUMAMIT8 in regulating the growth and development and quality of forage grass. The biological function of the gene MtUMAMIT8 is identified for the first time, the MtUMAMIT8 gene is screened and locked through multi-omics analysis, and the phenotype of the homozygous mutant NF8465 / NF12630 is analyzed, confirming that the down-regulation of the gene MtUMAMIT8 leads to the growth of Medicago truncatula being hindered but the lignin content being reduced, and that the gene MtUMAMIT8 positively regulates the growth and development of the plant height, branch number and leaf size of Medicago truncatula and negatively regulates the synthesis of lignin, thereby providing a new gene resource for regulating the growth and development and quality of forage grass and breeding forage grass varieties with low lignin content.

Recombinant DNA molecules and constructs useful for modulating gene expression in plants, including molecules derived from Medicago truncatula sequences, are provided. Plants, plant cells, plant parts, and seeds comprising recombinant DNA molecules operably linked to heterologous transcribable DNA molecules are further provided, as are methods of their use.

The application relates to the field of biological technology, in particular to application of cyclic adenosine monophosphate in promoting biomass increase of pasture and root nodule, wherein the cyclic adenosine monophosphate significantly improves the fresh weight biomass of the above-ground part, the root part and the single-plant root system root nodule of Medicago truncatula inoculated with rhizobium, and the difference is significant.

This invention relates to the field of microbial technology and provides a highly efficient symbiotic nodulation strain of *Rhizobium sinense* 98002 and its applications. *Rhizobium sinense* 98002 was deposited on January 9, 2026, at the China General Microbiological Culture Collection Center (CGMCC), located at No. 3, Courtyard 1, Beichen West Road, Chaoyang District, Beijing, with accession number CGMCC No. 37337. The strain 98002 provided by this invention can not only form efficient symbiotic nodules with *Alfalfa* (from which it was isolated) but also achieve good symbiosis with the model plant *Alfalfa truncatum*, broadening its application scenarios. It can be used as a core strain to prepare highly efficient leguminous inoculants for agricultural production, reducing the use of chemical nitrogen fertilizers and improving the soil ecological environment.

The utility model discloses a simple threshing device for medicago truncatula so as to solve the technical problems that an existing threshing device is inconvenient to operate, low in efficiency and insufficient in safety. The inner bottom surface of the tray is provided with a lower rubbing surface, the bottom of the rubbing plate is provided with an upper rubbing surface, two sides of the top of the tray are provided with slideways, the upper part of the rubbing plate is connected with a cross beam, the rubbing plate is connected with the cross beam through a connecting rod, the cross beam is connected with the slideways in a sliding manner, and the cross beam is provided with a threaded hole. Threads corresponding to the threaded holes are arranged on the connecting rod, and the washboard is rotatably connected with the bottom of the connecting rod. The device has the advantages of being convenient to operate, high in working efficiency and good in safety.

The invention discloses an application of an LAP1 gene or an encoded protein thereof in regulation and control of physical dormancy of plants. It is found that compared with wild medicago truncatula, transgenic medicago truncatula obtained after the LAP1 gene separated from medicago truncatula is subjected to overexpression in medicago truncatula shows phenotypes such as water swelling or / and seed germination rate improvement and the like, and the transgenic medicago truncatula can be applied to the field of medicago truncatula. The physical dormancy of the transgenic medicago truncatula seeds is obviously broken. The method has application prospects in the aspects of promoting plant seed germination, reducing the production cost during seed germination and the like.
