Multi‐Omics Analyses Reveal the Red and Far‐Red Light Combination Enhancing Heterologous Protein and Metabolite Production in Nicotiana benthamiana

Plant, Cell &Environment, EarlyView.
ABSTRACT Transient expression of exogenous protein in Nicotiana benthamiana leaves via agroinfiltration offers a rapid and efficient platform for functional gene discovery and heterologous production of valuable eukaryotic proteins and metabolites. Though light quality is an important factor for plant photomorphogenesis, its impact on the efficiency of

Methyl Jasmonate Seed Priming Mitigates the Defence‐Growth Trade‐Off and Tailors Plant Response to Specific Pests

Plant, Cell &Environment, EarlyView.
ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.

Bioaccessibility of anthocyanins and bioactive compounds from Brazilian berries and their food matrix interaction: an in vitro gastrointestinal digestion study coupled to UHPLC‐ESI‐TQD‐MS/MS analysis

Journal of the Science of Food and Agriculture, Volume 106, Issue 6, Page 3462-3477, April 2026.
Abstract BACKGROUND Several commercial berries have been examined for anthocyanin composition, bioaccessibility, and bioactive effects, while Brazilian berries remain underexplored. This study aimed to access the effect of in vitro gastrointestinal digestion on anthocyanin bioaccessibility, stability, and antioxidant potential in black pitanga (Eugenia

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

Molecular 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.
