TLDR
Root extracts, prepared from young Lens culinaris seedlings, are analysed after a gel chromatography on Sephadex G-25 and G-100 and IAA-oxidase, peroxid enzyme and polyphenoloxidases activities were found in the same fractions.Abstract:

The Saliva of Hemiptera
TL;DR: This chapter compiles the various types of investigation on salivary functions in the Homoptera and Heteroptera, and suggests profitable lines of future investigation based on analogous functions in different taxonomic groups.
Journal ArticleDOI
Peroxidase activity in healthy and leaf-rust-infected wheat leaves
TL;DR: The ratio of activities in these two groups did not differ between 9-day-rusted LR10(TC) and healthy tissue, although total peroxidase was considerably greater in infected tissues, which suggests that the two forms may be related.
Journal ArticleDOI
Iaa oxidase and polyphenol oxidase activities of peanut peroxidase isozymes
TL;DR: Four anionic isozymes from peanut cells in suspension medium possessed IAA oxidase and polyphenol oxidase activities and the sigmoid kinetics from the IAA oxidation assays probably indicates an allosteric nature.

Rapid release of peroxidase by peanut cells in suspension culture
R. B. van Huystee,G. Turcon +1 more
TL;DR: It was established that protein released into the medium had the same molecular weight as the peroxidase found in this medium by means of gel filtration on Sephadex G-200 and it may be deduced that the metabolic rate of these cells is very high.

Peroxidase and IAA-oxidase activities during rooting in cuttings of three poplar species.
TL;DR: Peroxidase activity started to increase the early stages of primordium formation and reached the highest level before root emergence and a positive correlation between rooting and IAA-O activity was observed.

Protein Measurement with the Folin Phenol Reagent
TL;DR: Procedures are described for measuring protein in solution or after precipitation with acids or other agents, and for the determination of as little as 0.2 gamma of protein.

Partial Purification and Kinetics of Indoleacetic Acid Oxidase from Tobacco Roots
Luis Sequeira,Lorraine Mineo +1 more
TL;DR: Tobacco roots contain an IAA oxidase which may have higher affinity for IAA and may be more specific than the general peroxidase system previously described from other plant sources.

Studies on Polyphenol Content, Activities and Isozymes of Polyphenol Oxidase and Peroxidase During Air-Curing in Three Tobacco Types
S. J. Sheen,J. Calvert +1 more
TL;DR: Results suggest that in the crude tobacco leaf extract the peroxidase and polyphenol oxidase may associate as protein complexes, and peroxIDase isozymes may differ in electron-donor requirements.
