Chromosome‐Level Genome Assembly of the Allotetraploid Gynostemma pentaphyllum Provides Novel Insights Into the Biosynthesis of Ginsenoside and Gypenoside LVI

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Gynostemma pentaphyllum, a herb used in tea and traditional Chinese medicine, shows geographic variation in its production of valuable dammarane‐type ginsenosides and gypenoside LVI between populations from Suining (SN) and Nanning (NN). To elucidate the mechanisms underlying this differential metabolite accumulation, a chromosome‐level genome

Multi‐Omics Insights Into Anthraquinone Biosynthesis in Rheum tanguticum

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Rheum tanguticum is renowned for its medicinal properties, including purgative, anti‐inflammatory and hepatoprotective effects, primarily attributed to anthraquinones (AQs). However, the molecular mechanisms of AQs biosynthesis have largely been hindered by insufficient genomic resources and functional genomics investigations.

Distinct Defence Mechanisms of Allelopathic Rice Against Quinclorac‐Susceptible and ‐Resistant Barnyardgrass: Involvement of Specific Metabolites and Rhizosheath Microbiota

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Allelopathic rice is increasingly recognised as a promising strategy for sustainable weed management. Resistance to the herbicide quinclorac is widespread in barnyardgrass, but it remains unclear whether allelopathic rice exerts the same defence against herbicide‐susceptible and ‐resistant barnyardgrass. We conducted integrated transcriptomic,

A Combination of Xanthohumol and Ursolic Acid in the Diet Leads to Synergistic Inhibition of Prostate Cancer Progression

open access: yesMolecular Carcinogenesis, Volume 65, Issue 4, Page 508-522, April 2026.
ABSTRACT Prostate cancer (PCa) is the second most common cancer and second leading cause of cancer death for American men. Chemoprevention by using phytochemicals offers a promising approach to improve outcomes due to their ability to act on cancer cell metabolism and growth while maintaining low toxicity profiles.
