However, its substrate utilization and degradation mechanisms remain poorly understood. To explore this, we cultured <em>O. raphanipes</em> mycelium in Kirk's liquid medium supplemented with eight distinct substrates and conducted studies on extracellular enzyme activities and secretome analysis. A total of 905 secreted proteins were identified, with the cornstalk group having the highest counts. Carbohydrate-active enzymes (CAZymes) were the predominant type (32.8–48.9 %), followed by oxidoreductases (2.8 %–13.3 %), while lipase and phosphatase were minor categories. Functional annotation of the secreted proteins comprehensively revealed their diversity in various biological processes. Among the 340 secreted proteins with Enzyme Commission codes, (Methyl)glyoxal oxidase, chitinase, and β-glucosidase were most prominent. Bran, cottonseed hulls, corncobs, and the mixture promoted mycelium growth and conserved CAZymes expression patterns. In contrast, sawdust, corn steep liquor, and cornstalk induced divergent secretome profiles. Sawdust led to a higher proportion of hemicellulose- and lignin-degrading enzymes. Corn steep liquor induced relatively high activities and abundances of laccase and MnP, while cornstalk induced a broad spectrum of oxidoreductases, lipases, and protease &amp; peptidases.

Shoot tissues can accumulate high concentrations of sodium over time through the transpiration stream coming from the roots.

The role of metabolic processes in generating and responding to these increases in sodium concentration over time was explored by linking changes in ion distributions to those of enzyme abundance from the base to the tip of leaves under salt stress. We found that enzymes for methionine synthesis and lipid degradation pathways increase, concomitantly with proteins in jasmonate synthesis, which are key players in plant stress-induced responses. Combining the use of Differential Abundance of Protein analysis and Weighted Correlation Network Analysis we have focused on identifying key protein hubs associated with responses to salt stress or salt susceptibility, shedding light on potential sites of salt sensitivity as targets for enhancing salt tolerance in wheat.

Immunohistochemistry (IHC) and spatial proteomics based on mass spectrometry imaging (MSI) are used to detect proteins in tissue samples. IHC can detect precisely but has a limited throughput, whereas MSI can simultaneously visualize thousands of specific chemical components but hindered by detailed protein annotation. Thereby, the introduction of mass tags may be adopted to expand the potential for integrating MSI and IHC. By enriching optical information for IHC and enhancing MS signals, mass tags can boost the accuracy of qualitative, localization, and quantitative detection of specific proteins in tissue sections, thereby widening the scope of protein detection and annotation results. Consequently, more comprehensive information regarding biological processes and disease states can be obtained, which aids in understanding complex biological processes and disease mechanisms and provides additional perspectives for clinical diagnosis and treatment. In the current review, we aim to discuss the role of different mass tags (e.g., mass tags based on inorganic molecules and organic molecules) in the combined application of MSI and IHC.</div></div>","PeriodicalId":16891,"journal":{"name":"Journal of proteomics","volume":"316 ","pages":"Article 105436"},"PeriodicalIF":2.8,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143780320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nitrogen concentration is a critical factor influencing protein accumulation. Unfortunately, nitrogen deprivation often negatively impacts biomass production. Understanding the relationship between nitrogen concentration and protein accumulation is crucial for harnessing the potential of microalgae in various industries and addressing environmental challenges. Here, we quantitatively compared the proteomic profiles of <em>Chaetoceros muelleri</em> diatom, grown in two Nitrogen-deficient conditions and control treatment by employing a Tandem Mass Tag-based quantitative proteomic approach. Proteins involved in photosynthesis were differentially accumulated under moderately nitrogen-deficient conditions. In contrast, proteins involved in cell signaling and protection mechanisms were differentially accumulated under severely nitrogen-limited conditions. Proteins associated with nitrogen metabolism, carbohydrate metabolism, and protein biosynthesis were differentially decreased in severely nitrogen-limited conditions, indicating differential response mechanisms of <em>C. muelleri</em> to varying nitrogen conditions. Our results show that <em>C. muelleri</em> employs distinct strategies in response to nitrogen limitation. These results provide valuable insights into the adaptive strategies of <em>C. muelleri</em> under nitrogen limitation, offering potential applications in optimizing microalgal cultures for the enhanced production of target metabolites in industrial bioreactors.</div></div><div><h3>Biological significance</h3><div>The marine diatom <em>Chaetoceros muelleri</em> accumulates lipids and carbohydrates under low nitrogen conditions without affecting its biomass. Response to nitrogen limitation in <em>C. muelleri</em> was examined by isobaric labelling-based proteomics. We identified changes mainly focused on photosynthesis pathways, cell signaling and protection mechanisms, nitrogen and carbohydrate metabolism, as well as protein biosynthesis. Our results indicate that <em>C. muelleri</em> activate unique strategies in response to different nitrogen concentrations, and this differential response represents a key factor for inducing metabolite accumulation without affecting biomass production.</div></div>","PeriodicalId":16891,"journal":{"name":"Journal of proteomics","volume":"316 ","pages":"Article 105435"},"PeriodicalIF":2.8,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143692595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
