Aging and longevity in decades‐old genebanked seeds from U.S. endangered plant species: Assessments using survival and RNA integrity assays

open access: yesAmerican Journal of Botany, Volume 113, Issue 3, March 2026.
Abstract Premise Seed longevity is critical for successful genebanking, but it is hard to detect or predict. We examined survival of genebanked seeds from species native to the United States to estimate longevity. We tested whether RNA integrity (RIN) can be used to detect aging and predict mortality. Methods Dry seeds from >100 species were stored for

A Digestive Herbal Mixture Preparation Stimulates Proton Secretion in Human Parietal Cells through Phenolic Compounds Targeting Bitter Taste Receptors

open access: yesMolecular Nutrition &Food Research, Volume 70, Issue 6, 29 March 2026.
Polyphenol‐rich herbal extracts stimulate proton secretion in human parietal cells (HGT‐1) via activation of extra‐oral bitter taste receptors (TAS2Rs). A commercially available herbal mixture preparation and its nine solvent extracts show concentration‐dependent effects correlating with total polyphenol content.
