Alcoholic extracts of Russian sage (Salvia yangii) contain bioactive terpenoids with inhibitory activity against grapevine downy mildew (Plasmopara viticola)

Pest Management Science, EarlyView.
Alcoholic extracts from flowers, leaves, and shoots of Russian sage decreased downy mildew severity on grapevine leaf disks. Fractionation followed by metabolomic analysis revealed putative terpenoids as the main components of the active fractions. Specifically, 7‐methylrosmanol, 12‐O‐methylcarnosic acid, carnosic acid, and carnosol were identified as ...

Natural Products as Modulators of ABC Transporters in Breast Cancer

Phytotherapy Research, EarlyView.
ABSTRACT Breast cancer remains a significant global health challenge, with high incidence and mortality rates despite advancements in early detection and treatment. Multidrug resistance (MDR), particularly in aggressive subtypes like triple‐negative breast cancer (TNBC), continues to hinder effective therapy.

Revisiting the Molecular Roadmap for Sugar Crops: Genome Reading, Trait Writing and Variety Redesigning

Plant Biotechnology Journal, EarlyView.
ABSTRACT Sugar crops, including but not limited to sugarcane, sugar beet, sweet sorghum and stevia, are major sources of sugar production in the world. However, conventional breeding approaches, limited by long breeding cycles, low efficiency and restricted capacity to improve complex traits in sugar crops, are increasingly insufficient to address the ...
