Summary: This study explored the responses and adaptation mechanisms of Elymus nutans to cold, drought, and the combination of both stresses. The results showed that both cold and drought stress resulted in damage to the plants, but the combined stress had a more severe impact. Furthermore, the study revealed that the plants adapted to the cold and drought stress through osmotic adjustment and activation of transcription factors.

Summary: In this study, Rhizophagus irregularis was used to explore the mechanism regulating cold resistance of Elymus nutans. The results showed that AMF may regulate the cold-resistance of Gramineae grasses by affecting plant metabolism, antioxidant enzyme activities, and antioxidant-related metabolites like flavonoids and lipids. These results can provide some basis for studying the molecular mechanism of AMF regulating stress resistance of Gramineae grasses.

Summary: Using fluorescence in situ hybridization, researchers found the cross-species homoeology and syntenic relationship between E. sibiricus, E. nutans, and wheat chromosomes. They also identified distinct species-specific chromosomal rearrangements in E. sibiricus and E. nutans, which may be due to their different polyploidy processes. The frequency of intra-species polymorphic chromosomal rearrangements was higher in E. nutans than in E. sibiricus. These findings provide new insights into genome structure and evolution and will facilitate the utilization of germplasm diversity in both E. sibiricus and E. nutans.

Summary: In this study, the effects of cadmium (Cd) stress on the growth and physiological response of Elymus nutans Griseb. were investigated. The results showed that low concentration of Cd promoted the growth of the plant, while high concentration inhibited the growth. Cd stress also had a negative impact on the accumulation of chlorophyll.

Summary: This study extracted and identified two radical scavenging compounds from the methanolic extract of Elymus nutans Griseb. The compounds were successfully purified using medium-pressure and high-pressure liquid chromatography, resulting in high-purity target compounds. This methodology provides an effective approach for extracting high-purity flavonoids and radical scavengers from forage extracts.

Summary: The seed coat plays a crucial role in the plant life cycle, particularly in seed growth and development. It facilitates nutrient accumulation within the seed and protects the seed embryo from physical damage. Seed coat permeability is an important characteristic that affects both seed germination and the measurement of seed vigor using electrical conductivity. This study aimed to understand the mechanisms underlying seed coat permeability formation by analyzing the metabolome and transcriptome of Elymus nutans. The results identified key metabolites and genes, such as thiamine and salicylic acid, that influence seed coat permeability. Additionally, the study provided insights into the changes in metabolome and transcriptome during different stages of seed development. Understanding the factors influencing seed coat permeability is significant for seed production and quality evaluation.

Summary: This experiment studied the effects of PEG-6000 simulated drought stress and NaCl simulated salinization stress on the germination of E. nutans seeds, and explored the growth of forage seedlings from sowing to 28 days under drought and salinization stress conditions. Results showed that E. nutans was more severely affected by drought stress during both the seed germination and seedling growth stages compared to salinization stress. E. nutans exhibited better salt tolerance than drought resistance.

Summary: A molecular cytogenetic study was conducted on the allohexaploid species Elymus nutans with varying fertility. The research found that chromosome variants were unevenly distributed among genomes and among different homologue chromosomes. The findings also revealed significant correlations between fertility levels and chromosome variants, as well as correlations between seed setting rates and genome heterozygosity. Chromosome pairing analysis showed variations in chromosome configuration forms and frequencies, and the St and H genomes exhibited more chromosome structural variations than the Y genome. Overall, the fertility and genetic characteristics of E. nutans are influenced by genome heterozygosity and chromosome pair alterations.

Summary: This study investigated the microbial diversity, functionality, and fermentation quality of Elymus nutans (E. nutans) silage across different altitudinal gradients. The results showed that the silage from higher altitudes had better fermentation quality and higher abundance of lactic acid bacteria, while the silage from lower altitudes had undesirable microbial communities. The study also highlighted the impact of altitude on the microbial structure and nutrient distribution of forage, leading to varying levels of fermentation.

Summary: This study investigated the interaction between iron excess and phosphorus deficiency in Paspalum densum. The results showed that iron excess decreased phosphorus concentration in roots, while phosphorus deficiency increased iron concentration in leaves. Stomatal limitation was the main cause of decreased photosynthesis due to iron excess. Phosphorus deficiency contributed to higher phosphorus use efficiency and biomass.
