The epigenetic landscape of plant defense: Unlocking nature's toolkit for new plant protection

New Plant Protection, EarlyView.
This review examines how epigenetic mechanisms regulate plant immune gene activation, repression, and priming, then links these natural regulatory layers to emerging epigenetic editing, discussing their potential for precise, heritable crop protection and the challenges.

Production of Food and Feed Additives From Non-food-competing Feedstocks: Valorizing N-acetylmuramic Acid for Amino Acid and Carotenoid Fermentation With Corynebacterium glutamicum

Frontiers in Microbiology, 2018
Corynebacterium glutamicum is used for the million-ton-scale production of food and feed amino acids such as L-glutamate and L-lysine and has been engineered for production of carotenoids such as lycopene. These fermentation processes are based on sugars

Plasma and milk metabolomics in lactating sheep divergent for feed efficiency

Journal of Dairy Science, 2023
: Enhancing the ability of animals to convert feed into meat or milk by optimizing feed efficiency (FE) has become a priority in livestock research. Although untargeted metabolomics is increasingly used in this field and may improve our understanding of ...

Perturbation of Spermine Homoeostasis Uncouples Hypersensitive Cell Death From Systemic Plant Immunity

Plant, Cell &Environment, EarlyView.
ABSTRACT Polyamines are key regulators of plant stress responses, yet their contribution to coordinating local immune responses with systemic immunity remains poorly understood. Here, we investigated how spermine (Spm) homeostasis influences local and systemic defence responses in Arabidopsis thaliana following inoculation with Pseudomonas syringae pv.

Enantioselective Synthesis of Substituted Pipecolic Acid Derivatives

, 2016
Enantiomerically pure 4-piperidones, prepared by asymmetric [4 + 2] Diels−Alder cycloadditon of chiral 2-aminodienes with imines, have been used as starting materials for the synthesis of several derivatives of pipecolic acid.

Novel Amino Acid Changes Increase Phosphoenolpyruvate Carboxylase Output in planta

Plant, Cell &Environment, Volume 49, Issue 11, Page 8306-8321, November 2026.
ABSTRACT Characterization of previously reported Arabidopsis mutants with increased aluminum (Al) resistance (alr) resulting from greater release of Al‐chelating malate identified three unique amino acid substitutions that each impacts PHOSPHOENOLPYRUVATE CARBOXYLASE 1, a key anaplerotic carbon fixation enzyme.

Optimization of the precursor supply for an enhanced FK506 production in Streptomyces tsukubaensis

Frontiers in Bioengineering and Biotechnology, 2022
Tacrolimus (FK506) is a macrolide widely used as immunosuppressant to prevent transplant rejection. Synthetic production of FK506 is not efficient and costly, whereas the biosynthesis of FK506 is complex and the level produced by the wild type strain ...

Polyphenol‐Rich Foods as a Healthy and Sustainable Strategy: Mental Health and Metabolomic Profiling

Molecular Nutrition &Food Research, Volume 70, Issue 19, 15 October 2026.
A 12‐week nutritional intervention with cocoa flavanols and red‐berry anthocyanins in older adults improved emotional well‐being and identified metabolomic signatures associated with the intervention through urinary metabolome profiling. ABSTRACT The so‑called demographic transition has increased the prevalence of chronic diseases in adults over 65 ...
