Journal ArticleDOI
Function of polyphenol oxidase in higher plants
Kevin C. Vaughn,Stephen O. Duke +1 more
TL;DR: Polyphenol oxidase (PPO) is a plastidic enzyme that is unclear-coded, but is inactive until incorporated into the plastids, and may be involved in some aspect of oxygen chemistry – pherhaps mediation of pseudocyclic photophosphorylation.
Journal ArticleDOI
Role of peroxidase in the development of water-impermeable seed coats in Sida spinosa L
TL;DR: The results support the view that peroxidase is involved in the polymerization of soluble phenolics to insoluble lignin polymers during development of prickly sida seed coats, causing the formation of a water-impermeable barrier prior to seed dehydration.
Journal ArticleDOI
Polyphenol oxidase: The chloroplast oxidase with no established function
TL;DR: Polyphenol oxidase is apparently not involved in phenolic biosynthesis but is probably involved with the production of o-quinones during pathogen invasion and a role for PPO as an “oxygen buffer” is postulated, but little concrete data have been collected on any other functional role for this enzyme.
Journal ArticleDOI
Artemisinin, a Constituent of Annual Wormwood (Artemisia annua), is a Selective Phytotoxin
TL;DR: Artemisinin (qinghaosu), a sesquiterpenoid lactone peroxide constituent of annual wormwood (Artemisia annua L. # ARTAN) that is used as an antimalarial drug, was tested for phytotoxic properties as discussed by the authors.
Journal ArticleDOI
Mitotic Disrupter Herbicides
Kevin C. Vaughn,Larry P. Lehnen +1 more
TL;DR: Barban, propham, and chlorpropham have been shown to interact directly or indirectly with the microtubule as discussed by the authors, resulting in cells exhibiting an arrested prometaphase configuration.
