Divergent roles of ent‐kaurene oxidase paralogs in rice momilactone biosynthesis

Journal of Integrative Plant Biology, EarlyView.
Rice contains a five‐gene tandem array of genes encoding members of the ent‐kaurene oxidase (KO) family, with OsKOL4 and OsKOL5 playing divergent roles in momilactone metabolism, but both acting in the production of antifungal and antibacterial phytoalexins, which are important for disease resistance.

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 ...

Trichomes in Plant Defence, Development and Metabolic Integration Under Environmental Stress

Plant, Cell &Environment, EarlyView.
ABSTRACT Among various plant defence strategies, trichomes are tiny hair‐like structures on the epidermis that aid in defence, environmental adaptation and the production of valuable secondary metabolites. This review features trichomes as frontline guards for plant survival, integrating their structural, physiological and metabolic roles in ...

Flexibilins A–C, New Cembrane-Type Diterpenoids from the Formosan Soft Coral, Sinularia flexibilis

Marine Drugs, 2013
Three new cembrane-type diterpenoids, flexibilins A–C (1–3), along with a known cembrane, (−)-sandensolide (4), were isolated from the soft coral, Sinularia flexibilis. The structures of cembranes 1–4 were elucidated by spectroscopic methods.

Comparative Pharmacokinetics of Six Bioactive Constituents From Danggui Jixueteng Decoction in Normal and Myelosuppressive Rats

Analytical Science Advances, Volume 7, Issue 2, December 2026.
ABSTRACT This study compared the pharmacokinetics of six constituents from Danggui Jixueteng Decoction in normal versus carboplatin‐induced myelosuppressive rats. A rapid, sensitive ultra‐high performance liquid chromatography‐tandem mass spectrometry method was developed and validated for simultaneous quantification of six diverse constituents (8‐O ...

Chitosan‐induced modulation of secondary metabolism and stress tolerance in Salvia rosmarinus under combined drought and heat stress

Journal of the Science of Food and Agriculture, Volume 106, Issue 10, Page 5989-6001, 15 August 2026.
Abstract BACKGROUND Abiotic stresses, particularly drought and elevated temperatures, negatively affect plant physiological and metabolic processes. This study investigated the effects of drought, heat, and combined stress on Salvia rosmarinus (rosemary), and evaluated foliar‐applied chitosan as a biostimulant.
