Seasonality Affects the Phenolic Composition and Erythroprotective Activity of Ora‐Pro‐Nobis (Pereskia aculeata) Leaves

Chemistry &Biodiversity, Volume 23, Issue 2, February 2026.
ABSTRACT Ora‐pro‐nobis (OPN) is a food plant with polyphenol‐rich leaves. However, the influence of seasonality on their quantitative phenolic composition and how it impacts their bioactivities is unknown. OPN leaves were harvested throughout 12 months, and their individual phenolic content, antioxidant activity, and erythroprotection were assessed ...

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.

Dominated Spider Species and the Predation Assessment on Apolygus lucorum (Hemiptera: Miridae) in a Tea Plantation

Ecology and Evolution, Volume 16, Issue 2, February 2026.
The mirid bug Apolygus lucorum (Meyer‐Dür) is a major pest affecting tea. Identifying the dominant predatory spiders of the mirid bug can provide a scientific basis for developing biological control technologies. Xysticus ephippiatus demonstrates the greatest potential as a biological control agent against A. lucorum.

The Potential of Phytochemicals to Overcome Multidrug Resistance in Metastatic Melanoma

Chemistry &Biodiversity, Volume 23, Issue 1, January 2026.
ABSTRACT Metastatic melanoma is the most lethal form of skin cancer, accounting for most skin cancer‐related deaths. Immunotherapies and targeted therapies have improved overall and progression‐free survival rates in metastatic melanoma patients. The effectiveness of these therapies decreases due to multidrug resistance (MDR).

Reproductive phenology of tea (Camellia sinensis (L.) O. Kuntze) cultivars in Sri Lanka

Tropical Agricultural Research, 2018
Reproductive phenological attributes of the tea (Camellia sinensis (L.) O. Kuntze) plant have not been paid adequate attention until recently as the plant is being maintained continuously in the vegetative phase for commercial harvesting.

Natural Products Targeting the EGFR/HER2 Axis in Tumorigenesis: Interpretation of Molecular Mechanisms and Recent Insights Into Synergistic Strategies for Cancer Therapy

Food Frontiers, Volume 7, Issue 1, January 2026.
Schematic overview illustrating the anticancer mechanisms of selected natural products (resveratrol, quercetin, berberine) targeting EGFR and HER2 signaling pathways in tumor cells. These compounds inhibit receptor activation and downstream oncogenic cascades, including PI3K/Akt/mTOR, MAPK/ERK, and STAT3 pathways.

Transcriptomic analysis reveals the molecular mechanisms of drought-stress-induced decreases in Camellia sinensis leaf quality

Frontiers in Plant Science, 2016
The tea plant [Camellia sinensis (L.) O. Kuntze] is an important commercial crop rich in bioactive ingredients, especially catechins, caffeine, theanine and other free amino acids, which the quality of tea leaves depends on. Drought is the most important

Measurement of Ungulate Palatability and Browsing Pressure on Japanese Flora

Ecological Research, Volume 41, Issue 1, January 2026.
Estimation of palatability and browsing pressure are key techniques for ecosystem management. We compared four methods to estimate palatability based on browsing scar survey and proposed the reference palatability values for the Japanese flora as plant ecological trait.

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.
