These plants grew faster and entered the generative phase earlier than control plants, without showing any other developmental abnormalities. By the end of the generative phase, transgenic plants had greater dry mass and contained a higher proportion of carbohydrates than the control group. In result, they accumulated 14.9-17.5% more energy in the aboveground parts compared to reference plants.Conclusions: The high leaf specificity of the C. x morifolium Rubisco small subunit promoter was confirmed, indicating that transgene activity in leaves was effectively separated from its effects on metabolism in non-photosynthetic tissues. Overexpression of HvUGPase and HvSPP under this promoter accelerated plant growth and development, ultimately increasing biomass. These characteristics are particularly advantageous for energy crops grown as after-crops or in regions with short growing seasons.","PeriodicalId":94371,"journal":{"name":"Biotechnologia","volume":"106 1","pages":"31-48"},"PeriodicalIF":0.0,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12089933/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144121670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conditions, such as cardiovascular diseases, anxiety, and type 2 diabetes (T2D), are increasingly becoming public health threats, affecting even younger populations worldwide. In recent years, extensive research has uncovered the pivotal role of the human gut microbiome in various aspects of human physiology, including metabolism, cellular homeostasis, immune defense, and disease development. The gut microbiome, often referred to as the \"second brain,\" is now recognized as a key player in health and disease. Lifestyle factors such as diet, mental health, stress, exercise, and others significantly influence the composition of the gut microbiome. Imbalances in this composition, termed \"dysbiosis,\" have been linked to a wide range of diseases, including cancer, cardiovascular diseases, obesity, T2D, asthma, and neurological disorders like Alzheimer's and Parkinson's disease. These findings underscore the profound influence of gut microbiome health on overall well-being. A working understanding of the gut microbiome's composition and its impact on disease processes is crucial for the advancement of personalized or precision medicine. This review article aims to explore recent advancements in the field, shedding light on how the gut microbiome contributes to the development and prognosis of lifestyle diseases.","PeriodicalId":94371,"journal":{"name":"Biotechnologia","volume":"106 1","pages":"103-122"},"PeriodicalIF":0.0,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12089934/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144121677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, studies on these new mutant lines remain limited. This study aimed to determine and compare the biochemical characteristics and transcriptomic profiles of drought-tolerance-related genes in ML 82-2 and ML 125-2, as well as in the parent lines, IS21 and MR220.Materials and methods: Seeds were germinated for 14 days under a controlled photoperiod (16 h light and 8 h darkness) at a constant temperature of 25 ± 2°C. Biochemical analyses, including total soluble protein content, specific peroxidase activity (SPA), chlorophyll content, and proline content, were conducted. Transcriptomic profiling was performed using STRING and gene ontology (GO) enrichment analysis.Results: ML 82-2 exhibited the highest SPA, which was significantly different from that of MR220 and IS21, as well as significantly different total soluble protein content. However, ML 82-2 did not significantly differ from MR220 in chlorophyll and proline content. Drought stress-responsive genes Os01g0124401, Os08g0473900, and Os08g0518800 were identified in ML 82-2. Conversely, ML 125-2 displayed total soluble protein content and SPA similar to IS21, while chlorophyll and proline content were not significantly different from those of MR220. Drought stress-responsive genes Os10g0471100, Os01g0197100, and Os11g0701400 were identified in ML 125-2.Conclusions: ML 82-2 demonstrated improved SPA, whereas ML 125-2 exhibited enhanced total soluble protein content. The identified genes in both mutant lines are associated with drought resistance, with most sharing a similar genomic profile with MR220. These findings contribute to plant physiology studies and stress-responsive gene discovery in rice.","PeriodicalId":94371,"journal":{"name":"Biotechnologia","volume":"106 1","pages":"13-30"},"PeriodicalIF":0.0,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12093092/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144121893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, salinity stress can hinder its growth. This study examines the effects of salinity on the morpho-biochemical traits of spinach in a hydroponic system.Materials and methods: Spinach seeds were sown on coco peat, and after 10 days, the seedlings were transferred to the hydroponic setup. The plants were treated with salt concentrations of ECe 0, 4.0, 6.0, 8.0, 10.0, and 12.0 ds/m, and various morpho-biochemical parameters were assessed at 10-day intervals.Results: In the control group, seed germination was 59.6 ± 1.45%, while increasing salt concentrations (4 to 10 dS/m) progressively reduced germination (50 ± 1.2% to 14 ± 2%). Root and shoot lengths (root: 14.16 ± 0.19 cm; shoot: 4.23 ± 0.28 cm at 4 dS/m), relative water content (47.5 ± 0.43% to 32.1 ± 0.86%), and leaf surface area (25.03 ± 0.26 to 9 ± 0.12 cm2) all declined with increasing salinity. Conversely, proline content (0.055 ± 0 to 0.12 ± 0 μg/ml) and antioxidant enzyme activity (SOD: 1.83±0.04/g protein; APX: 0.53 ± 0.1/mg protein; CAT: 0.0054 ± 0/mg protein) increased compared to the control.

Despite the availability of the antituberculosis Bacille Calmette-Guérin (BCG) vaccine, its efficacy varies (0%-80%) and gradually decreases over time. This study aimed to identify cytotoxic T-lymphocyte (CTL) and helper T-lymphocyte (HTL) epitopes in MTb secretory proteins using immunoinformatics tools.Materials and methods: The Protein Variability Server was used to identify highly conserved sequences, and epitope population coverage was estimated for the Southeast Asian (SEA) region. Selected epitopes were also docked to their major histocompatibility complex alleles.Results: Five secretory proteins critical to MTb pathogenesis and virulence were identified as antigenic (antigenicity score > 0.4). Predicted epitopes had IC50 values ≤ 500 nM, indicating strong binding affinity, with an estimated 94% population coverage in SEA. All candidate epitopes were highly conserved (Shannon index ≤ 0.1) and showed no significant sequence similarity to human proteins, allergens, or toxic peptides. Docking analysis confirmed favorable binding to their corresponding HLA alleles, as indicated by low Gibbs free energy change (ΔG) values and dissociation constants (K D nM).Conclusions: Overall, this study identified immunoactive CTL and HTL epitopes that could serve as promising candidates for future antiTB vaccine development.

Various microenvironments, including dental enamel, supra- and subgingival surfaces, salivary fluid, and the dorsal surface of the tongue, harbor diverse microbes. These biofilms typically consist of four major layers. Depending on the food, age, clinical state, and lifestyle of the patient, the microbial growth dynamics in oral biofilm varies significantly. The presence of pathogenic bacteria that disrupt the normal floral composition of the oral cavity can lead to plaque biofilm formation, which is a precursor to various diseases. Noteworthy pathogenic bacteria, such as Porphyromonas gingivalis, Fusobacterium nucleatum, and Streptococcus mutans, often initiate biofilm formation. Undiagnosed and untreated oral biofilm can lead to severe diseases like periodontitis and eventual tooth loss. Therefore, studying the architecture and dynamics of oral biofilms is essential and can be achieved through image analysis and modern technologies, such as AI-enabled technologies and surface topography-adaptive robotic superstructures.","PeriodicalId":94371,"journal":{"name":"Biotechnologia","volume":"105 4","pages":"395-402"},"PeriodicalIF":0.0,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11748217/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143026192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
