Summary: Nitrogen addition can alter the reproductive strategy and growth patterns of Leymus chinensis, leading to higher investment in vegetative and clonal organs, and lower investment in sexual organs. The optimal N addition rates for sexual reproduction, vegetative growth, and clonal reproduction were found to be 16 g N m^(-2) and 32 g N m^(-2) respectively.

Summary: Intraorganismal genetic heterogeneity (IGH) refers to the existence of multiple genotypes within the cells of an individual organism. This study used Sanger and high-throughput sequencing to analyze nucleotide mutations in Leymus chinensis, employing different species, organs, DNA segments, and single cells. The findings showed that Leymus chinensis is composed of cells with different genetic backgrounds, as evidenced by excessive genetic heterogeneity in nuclear DNA but consistency in chloroplast genes. The study also revealed a high density of single nucleotide polymorphisms (SNPs) in the variants of the unique DNA sequence, suggesting non-random nucleotide mutation following certain rules.

Summary: The lack of genome editing platforms has hindered the study and improvement of forage crops that can be grown on lands not suitable for other crops. This study established an efficient CRISPR/Cas9 genome editing method in a stress-tolerant forage grass called sheepgrass, and knocking out the TB1 gene significantly increased tiller number and biomass.

Summary: This study investigated the physiological and metabolic mechanisms of perennial grass response to alkali stress using Leymus chinensis as the experimental material. The results showed that alkali stress inhibited seedling growth and photosynthesis, but increased nitrogen and ATP contents. Metabolic analysis revealed an increase in nucleotides, amino acids, and organic acids, while soluble sugar contents decreased under alkali stress. The glutamine synthetase/glutamate synthase (GS/GOGAT) cycle, associated with nitrogen metabolism, was the most significantly affected pathway. The study highlights the roles of amino acids, organic acids, nucleotides, and the GS/GOGAT cycle in the response of seedlings to alkali stress.

Summary: Forcing culture with defoliation and gibberellin treatment enhances photosynthesis and non-structural carbohydrate assimilation in tree peony, with gibberellin potentially inducing PsSWEET7 for more efficient NSC allocation. The sugar signaling pathway is also involved in NSC-coordinated tree peony flowering, with PsSnRK1 playing a key role in the bracts.

Summary: This study combined climatic factors and plant characteristics to analyze the individual aboveground biomass (AGB) of Leymus chinensis in northern China, and established a non-destructive prediction model. The results showed that plant traits (PH, SD) were the main factors driving the AGB of L. chinensis individuals, and climate factors mainly affected AGB indirectly by influencing plant traits. The established AGB estimation equation for L. chinensis individuals across large scale showed high predictive ability.

Summary: In this study, the ecological adaptations of Leymus chinensis to temperate steppe were examined by measuring soil and plant chemical elements. The results showed that with increasing latitude, both the foliar N and P contents of L. chinensis showed parabolic trends with significant negative correlations. The population of L. chinensis was limited by N, and the soil TN content showed a significant increasing trend with the increase in the foliar N:P ratio. The foliar N, P, and N:P ratio of L. chinensis showed absolute stability and strong internal stability in different latitude intervals.

Summary: The increasing atmospheric nitrogen deposition has significant impacts on nitrogen availability and photosynthetic capacity of terrestrial plants. This study reveals that within-leaf nitrogen allocation optimization is a key adaptive mechanism for plants to maximize their photosynthetic nitrogen-use efficiency and biomass under predicted future global changes.

Summary: This study investigated the adaptation of Leymus chinensis root exudates to different degraded levels of soil and the mechanism of rhizosphere restoration. The research found that the metabolic characteristics of root exudates were significantly influenced by soil degradation, with changes in lipid metabolism pathways and energy metabolism pathways to help plants adapt to unfavorable soil conditions.

Summary: The Leymus chinensis populations in the southwestern Songnen Plain are threatened by increasing soil salinity and alkalinity, despite their tolerance to salt and alkali stress. Nitrogen content was found to be more sensitive to saline-alkali stress than phosphorus content, with the highest N and P content observed at pH 8.4. Exposure to 14-day incremental intervals of saline-alkali stress had weaker effects on the plants. When lacking in nitrogen, applying N fertilizer was found to be extremely efficient.

Summary: Oedaleus decorus asiaticus is a harmful pest in Inner Mongolia, China that causes serious problems in animal husbandry and agriculture. This study used a UAV with a camera to collect multi-spectral data and analyzed nine vegetation indices to estimate plant loss caused by O. decorus at different growth stages. The results showed that the density and growth stage of O. decorus have a significant impact on plant loss.

Summary: This study investigated the response of carbon and nitrogen metabolism coordination in the dominant grass species Leymus chinensis to different nitrogen addition levels in a semiarid grassland in northern China. The results showed that moderate nitrogen levels promoted photosynthesis and increased photosynthetic capacity, while higher nitrogen levels promoted nitrogen investment in nonphotosynthetic pathways. Nitrogen addition also stimulated the accumulation of carbon and nitrogen compounds across organs by activating metabolic enzymes, and triggered the transformation of primary metabolites to secondary metabolites. L. chinensis demonstrated adaptability to different nitrogen addition levels by adjusting the allocation of carbon and nitrogen metabolic compounds.
