Whole‐genome data shed light on speciation and within‐species differentiation of the Papilio machaon complex around the Mediterranean Basin

open access: yesSystematic Entomology, Volume 50, Issue 4, Page 692-712, October 2025.
Genomic data refine the species boundary of Papilio machaon and confirm the species status of Papilio saharae, with clarification of subspecies delineation of Mediterranean machaon and saharae. A heterogeneous level of genome‐wide heterozygosity between island and continental lineages warrants further taxonomic implications, and there is also evidence ...

Floral Origin Determines the In Vitro Antibacterial Activity of Bee Pollen Collected From Western Oromia, Ethiopia

open access: yesFuture Postharvest and Food, Volume 2, Issue 3, Page 325-334, September 2025.
ABSTRACT Bee pollen has been used as a medicine and food supplement. The biological activity and nutrient composition of bee pollen depend on its floral origin. Therefore, it was aimed to determine the phenolic and flavonoid content and antibacterial activities of methanolic (99.9%) extract of bee pollens among flora. Floral origin was identified using

Piceatannol, a Natural Polyphenol From Grape, Inhibits Helicobacter pylori Through Targeted Suppression of Its Secreted Urease

open access: yesFood Science &Nutrition, Volume 13, Issue 9, September 2025.
Piceatannol significantly inhibits the growth of Helicobacter pylori through targeted suppression of its secreted urease activity. The inhibition of piceatannol against H. pylori urease (HPU) and jack bean urease (JBU) was characterized in a slow‐binding, mixed‐type and slow‐binding, noncompetitive type, respectively.

Progestogens and androgens influence root morphology of angiosperms in a brassinosteroid‐independent manner

open access: yesThe Plant Journal, Volume 123, Issue 5, September 2025.
Significance Statement Plants produce progesterone and androgens, which alter root morphology in A. thaliana and 60% of tested angiosperms. Brassinosteroids seem uninvolved. Understanding the mechanism is like navigating an unknown city—exemplarily Dittelbrunn (a small village in Bavaria)—where the expected shortcut (interaction with brassinosteroids ...
