Medicinal Plants and Lead Phytomolecules as Immunomodulators: An Updated Review

BioMed Research International, Volume 2026, Issue 1, 2026.
All therapeutic interventions aimed at modulating the immune response to pathogens, self‐antigens, carcinogens, or xenogeneic antigens are referred to as immunomodulation, which either prevents hyperactivation or restores the appropriate response of the immune system.

Diversity Analysis of Diazotrophic Bacteria Associated with the Roots of Tea (Camellia sinensis (L.) O. Kuntze)

Journal of Microbiology and Biotechnology, 2011
The diversity elucidation by amplified ribosomal DNA restriction analysis and 16S rDNA sequencing of 96 associative diazotrophs, isolated from the feeder roots of tea on enriched nitrogen-free semisolid media, revealed the predominance of Gram-positive over Gram-negative bacteria within the Kangra valley in Himachal Pradesh, India.

Guizhou Green Tea Metabolomics Analysis: Volatile Metabolites Based on HS‐GC‐IMS and UPLC‐Q‐TOF‐MSMS and Quality Evaluation

International Journal of Food Science, Volume 2026, Issue 1, 2026.
This study identifies metabolite profiles associated with aroma variations among three Guizhou green teas (Meitan Cuiya, Meitan Maofeng, and Duyun Maojian) using integrated HS‐GC‐IMS and UPLC‐Q‐TOF‐MSMS analysis. We identified 57 volatile organic compounds and 159 phenolic compounds, with 22 compounds exhibiting relative odor activity values (rOAVs ...

The Evolution of Gallic Acid in Aged White Tea and Its Potential Anti‐Aging Mechanisms: An Integrated Study Combining Network Pharmacology and Computer Simulation

Food Science &Nutrition, Volume 13, Issue 12, December 2025.
In this study, HPLC was used to analyze the evolution of GA content and to determine the antioxidant capacity of aged white tea. Results revealed that the GA content increased with storage time, accompanied by a corresponding enhancement in the antioxidant potency composite index.

Organization of 5S ribosomal RNA genes in tea (Camellia sinensis)

, 2001
The 5S rRNA genes in the Camellia sinensis (L.) O. Kuntze (tea) genome are arranged as tandem repeat units of 300 and 325 bps. The 2 classes of tandem repeats were discovered by Southern hybridisation of tea genomic DNA with a 5S rRNA gene PCR product ...

Do leaf surface characteristics affectAgrobacterium infection in tea [Camellia sinensis (L.) O Kuntze]?

Journal of Biosciences, 2004
The host range specificity of Agrobacterium with five tea cultivars and an unrelated species (Artemisia parviflora) having extreme surface characteristics was evaluated in the present study. The degree of Agrobacterium infection in the five cultivars of tea was affected by leaf wetness, micro-morphology and surface chemistry.
