Project description:<p> Elymus breviaristatus is an important alpine forage, there is limited information regarding its potential use as silage and how fertilizer treatments affect the ensiling process in this forage crop. Here, we investigated how organic fertilizer (M), nitrogen-phosphorus-potassium fertilizer (NPK), and Trichoderma harzianum fertilizer (B) affect E. breviaristatus silage quality (30 days and 60 days ensiling) via microbiome and metabolome analyses. Before ensiling, plant height and chlorophyll content increased by 29.93% and 39.72%, respectively, in the B group. After 60 days of ensiling, the M group had reduced crude protein and elevated butyric acid, the NPK group had higher ammonia nitrogen and butyric acid, and the B group had increased crude protein and lactic acid. These quality shifts correlated with microbial and metabolic changes. In the M group, alpha-linolenic acid metabolism was downregulated and Alternaria enriched, while the NPK group had enhanced flavone biosynthesis and a reduced level of Lactiplantibacillus. The B group had enhanced glycine, serine, and threonine metabolism, and displayed the most complex microbial networks along with increased levels of Lactiplantibacillus and Aspergillus. Overall, these results demonstrate that Trichoderma-based fertilization enhances silage quality by promoting accumulation of beneficial microbes and increasing flux through specific metabolic pathways, potentially offering a sustainable strategy for alpine forage improvement.</p>

Project description:A proteomic and metabolomic approach was conducted to decipher the biochemical bases of silage maize N utilization and metabolism in relation to growth and productivity. Leaf samples were collected on plants cultivated in the field, where they were subjected to optimal and low N fertilization treatments. The proteomic and metabolomic responses to low N was thus analyzed in 29 hybrids (29 different dent inbred lines crossed with the same flint inbred line). Ecophysiological and agronomic traits were measured on plants cultivated in the same fields. Multivariate analyses allowed us to connect the data obtained at these different levels of integration and to analyse the genetic variation of susceptibility to low N.

Project description:The purpose of this study was to explore the mechanism of aerobic decay of whole-plant corn silage and the effect of Neolamarckia cadamba essential oil on aerobic stability of whole-plant corn silage. Firstly, the dynamic changes of temperature, microbial community and metabolite content after aerobic exposure of whole-plant corn silage were determined, and the main microbial species and mechanism leading to aerobic spoilage of whole-plant corn silage were analyzed. The N. cadamba essential oil was extracted from fresh N. cadamba leaves by steam distillation, and the minimal inhibitory concentration, antibacterial stability and bacteriostatic mechanism of N. cadamba essential oil against undesirable microorganisms in whole-plant corn silage were determined. According to the minimum inhibitory concentration of N. cadamba essential oil on undesirable microorganisms in silage, N. cadamba essential oil was added to whole-plant corn silage to explore the effect of N. cadamba essential oil on the aerobic stability of whole-plant corn silage.
