Knocking Out Two Polyphenol Oxidase Genes Significantly Improves Recombinant Protein Purification in Nicotiana benthamiana

Plant Biotechnology Journal, EarlyView.
ABSTRACT Efficient purification remains a key technical challenge affecting the recovery efficiency of recombinant proteins in plant‐based systems. Complex metabolites, particularly polyphenols, often cause recombinant protein aggregation during purification.

Unexpected Suppression of Tomato Fruit Cuticle Formation by Overexpression of a Key Cutin Biosynthetic Enzyme

Plant Biotechnology Journal, EarlyView.
ABSTRACT Fruit cuticles regulate the diffusion of water, gases and solutes, functioning as essential protective interfaces against environmental and biotic stresses. Engineering cuticle structure and mechanics therefore represents a promising strategy for improving fruit quality and resilience.

Constitutive Metabolomic Profiles Linked to Seasonal Climate Niche Adaptation and Resilience to Black Rot in Cabbage

Plant, Cell &Environment, EarlyView.
ABSTRACT Plants are dynamic chemical factories that produce diverse specialised metabolites essential for growth, defence, and environmental adaptation. Metabolomes, shaped by genetic architecture, enable plants to respond to abiotic and biotic pressures, including temperature fluctuations.

DPPH Radical Scavenging Activity of Chlorogenic Acid Related Compounds and their Effects against Mouse Macrophage-like Cells [PDF]

, 2003
P(論文)Green coffee contains a large amount of polyphenols, especially caffeoyl quinic acid (CQA) related compounds. Using TOYOPEARL HW-40F column chromatography, five fractions (I～V) were separated from green coffee bean extract.

Geometrical isomerization of hydroxycinnamic acid under UV‐light: Structural plasticity as a driver of metabolite complexity

Photochemistry and Photobiology, EarlyView.
UV irradiation drives metabolite complexity through photoisomerization of hydroxycinnamic acid‐containing compounds in plants. The olefin functional group of hydroxycinnamic acid enables structural plasticity through trans/cis isomerization. Multiple chromophores within a molecule can amplify UV‐induced transformations.
