Compared with the control, all the additives (especially the bacterium–enzyme combinations) increased the lactic acid (LA) concentration, water-soluble carbohydrate (WSC) content and relative abundance of <i>Lactobacillus</i>; decreased the pH, ammonia–nitrogen (AN) concentration, coliform count and relative abundance of undesirable bacteria such as <i>Enterobacter</i>; and facilitated lignocellulosic degradation.

By integrating plant physiology with transcriptomics and metabolomics analyses, we gained insight into the regulation of nicotine synthesis and metabolism in tobacco seedlings under different forms of nitrogen supply. Our findings revealed that ammonium nitrogen promotes nitrogen transformation in the root system of tobacco seedlings but inhibits root growth, whereas nitrate nitrogen inhibits biochemical processes but enhances root growth. Additionally, we observed that nitrate nitrogen facilitates the NAD + pathway in nicotine biosynthesis but inhibits the polyamine pathway, whereas ammonium nitrogen has the opposite effect. Overall, our comprehensive analysis indicates that the co-application of ammonium nitrate is conducive to nicotine synthesis. These results not only contribute to identifying key genes and metabolites involved in nicotine synthesis, but also provide a theoretical basis for establishing efficient regulation theories and pathways for tobacco's nitrogen utilization.

Moench) is a popular forage crop in arid and semi-arid areas due to its high drought tolerance, rapid growth, and low production costs. In addition, sweet sorghum, has relatively specific ensiling characteristics because of its high moisture content and sufficient amount of water soluble carbohydrates. Therefore, it is crucial to investigate the raw material characteristics and exogenous additive pretreatment for the regulation of silage quality. This study aimed to evaluate the effects of <i>Lactobacillus plantarum</i> (LP) and cellulase (CEL) on the fermentation profile, carbohydrate composition, in vitro rumen fermentation and microbiota communities of sweet sorghum silages with two different raw material characteristics (fresh sweet sorghum material (MC1); sweet sorghum material wilted outdoors for 6 h after chopping (MC2)).</p><h3>Results</h3><p>In this study, the sweet sorghum treatments were: control (without additives), LP, CEL, or a combination of LP and CEL (LP_CEL). All treated sweet sorghum samples were ensiled for 30 d. A higher content of lactic acid, propionic acid, D-fructose, glucose, sucrose and a lower content of structural carbohydrates were observed in MC1 silage than in MC2 silage. In MC2 silage, the addition of CEL or LP_CEL decreased the content of structural carbohydrates, while it increased the content of D-fructose, glucose, D-arabinose, xylitol, maltose and trehalose (<i>P</i> &lt; 0.05). The in vitro gas production at 48 h was greater in MC1 silage than in MC2 silage, and the addition of CEL or LP_CEL increased the in vitro dry matter digestibility in MC2 silage (<i>P</i> &lt; 0.05). After 30 d of ensiling, disaccharides such as sucrose, maltose and alginate were almost entirely utilized by the microorganisms, while more-consumed monosaccharides included D-fructose, glucose and L-rhamnose. <i>Lactobacillus</i> was the dominant genus (&gt; 80% relative abundance) in all silage samples.</p><h3>Conclusions</h3><p>Raw material characteristics determine carbohydrate composition, in vitro digestibility, and microbial community of sweet sorghum silage. For wilted sweet sorghum with relatively low moisture content, pretreatment with CEL or LP_CEL reduced the structural carbohydrate content, increased the nonstructural carbohydrate content, and improved the digestibility of the silage. However, additives had no obvious impact on enhancing the fermentation quality of sweet sorghum silage for two raw material characteristics.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":512,"journal":{"name":"Chemical and Biological Technologies in Agriculture","volume":"12 1","pages":""},"PeriodicalIF":5.2,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chembioagro.springeropen.com/counter/pdf/10.1186/s40538-025-00749-3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143554067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The technique facilitates the assessment of the composition and characteristics of the materials being analysed. Notably, NIR spectroscopy is characterised by its nondestructive nature, rapid execution, high sensitivity, ease of operation, and efficiency in analysis. In recent years, this technology has been widely applied and expanded in many fields, such as food analysis, biology, and medicine. Root crops, including but not limited to potatoes, cassava, yams, and sweet potatoes, are vital nutritional components of human diets and also serve as critical raw materials in food processing and industrial applications. The significance of these crops is underscored by their impact on consumer health and the economic viability of enterprises, thereby highlighting the importance of effective detection methods for these crops. NIR spectroscopy detection technology is capable of conducting thorough evaluations of both the internal qualities (e.g., starch, protein, sugars, and soluble solids) and the external qualities (e.g., appearance, morphology, pest infestations, and diseases) of root crops. In comparison with alternative spectroscopic techniques, NIR spectroscopy offers a more straightforward approach for the detection and analysis of root crop samples, whilst preserving the integrity of the samples. This emphasises the significant potential of NIR spectroscopy for real-time online monitoring of root crops. The present paper provides a concise overview of the principles underlying NIR spectroscopy detection technology and synthesises research findings regarding its application in the quality assessment of root crops. It emphasises recent advancements in the field, particularly concerning sample pretreatment, spectral collection and processing, and model development. The discussion further encompasses the advantages and limitations of NIR spectroscopy technology, along with the primary challenges encountered in its practical applications and prospects for future development.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":512,"journal":{"name":"Chemical and Biological Technologies in Agriculture","volume":"12 1","pages":""},"PeriodicalIF":5.2,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chembioagro.springeropen.com/counter/pdf/10.1186/s40538-025-00747-5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143554050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
