Purificiation and some properties of polyphenol oxidase from van apple (golden delicious)

open access: yes, 2006
Polyphenol oxidase was isolated from van apple, with a 4.0-fold purification of polyphenol oxidase by ammonium sulfate and DEAE cellulose being achieved. The optimum pH was 4 and for this enzyme, the optimum temperature was 50 degrees C.

Oxidation of polyphenols in unfermented and partly fermented cocoa beans by cocoa polyphenol oxidase and tyrosinase

open access: yes, 2002
Unfermented and partly fermented dried cocoa beans have an excessively astringent and bitter flavour owing to their high polyphenol content. Studies on the remaining polyphenol oxidase activity and the oxidation of polyphenols in these beans have been ...

The multidimensional regulation roles and mechanisms of calcium in fruit quality

open access: yesJournal of Integrative Plant Biology, EarlyView.
This review explores how calcium signaling molecule integrates plant hormones, environmental cues, and developmental signals to influence external fruit traits, internal nutritional properties, and physiological disorders. ABSTRACT Calcium (Ca2+), a dual‐functional mineral that serves both as an essential structural factor and a signaling molecule ...

Involvement of peroxidase and polyphenol oxidase in mango sap-injury.

open access: yes, 2002
Sap (latex) that oozes out from mangoes during harvest, upon contact with fruits, causes dark spots (sap injury) on the peel and reduces consumer acceptance and shelf-life of fruits.

Coniferyl aldehyde from the phenylpropanoid pathway targets pyruvate kinase in Dactylobotrys graminicola to confer sheath rot resistance in hulless barley

open access: yesJournal of Integrative Plant Biology, EarlyView.
Hulless barley resists the newly identified sheath rot disease caused by the necrotrophic fungal pathogen Dactylobotrys graminicola by releasing coniferyl aldehyde, a natural compound that disrupts energy production in the fungus. ABSTRACT Dactylobotrys graminicola (Dgr), a necrotrophic fungal pathogen, has recently been identified as the causative ...

Reconfiguring biofortification strategies to transform food systems and address micronutrient deficiency of the 21st century

open access: yesJournal of Integrative Plant Biology, EarlyView.
This review explores how to make staple foods and horticultural crops more nutritious, including how artificial intelligence‐based screening of gene banks helps deploy nutritionally rich germplasm into breeding. Genome editing can help develop crops richer in minerals, vitamins, and health‐promoting compounds, supporting healthier diets and more ...
