Convergence and parallelism in the evolution of plant metabolism

open access: yesJournal of Integrative Plant Biology, Volume 68, Issue 4, Page 1013-1031, April 2026.
Similar traits in different organisms may originate from shared ancestry or evolve independently. The terminology used to define phenotypic similarity is often confusing. This review attempts to clarify the definitions and present examples from plant domestication and specialized metabolism to explain how complex traits evolve repeatedly in plants ...

Assessment of Metabolites in Noni Fruit Slurry Fermented With Four Non‐Saccharomyces Yeasts

open access: yesFood Frontiers, Volume 7, Issue 2, March 2026.
Dried noni fruit slurry (DNFS) was fermented for 14 days with selected non‐Saccharomyces yeasts. GCMS, HPLC and amino acid analysis showed that Pichia kluyveri Frootzen and Williopsis saturnus NCYC22 grew well, reduced off‐flavor fatty acids, generated fruity aroma compounds and preserved total phenolic content. ABSTRACT Noni products often suffer from

Tomato‐Soy Juice Reduces Inflammation and Modulates the Urinary Metabolome in Adults With Obesity

open access: yesMolecular Nutrition &Food Research, Volume 70, Issue 5, 12 March 2026.
Compared to pre‐intervention, consuming a tomato‐soy juice (54 mg lycopene, 189 mg soy isoflavones/d) reduced levels of inflammatory cytokines (IL‐5, IL‐12p70, and GM‐CSF, with TNF‐alpha trending downward), increased plasma lycopene and urinary soy isoflavone metabolites, and altered the urinary metabolome. ABSTRACT Chronic, low‐grade inflammation is a
