Stimulation of indoleacetic Acid oxidase and inhibition of catalase in cotton extracts by plant acids.
نویسندگان
چکیده
Activity of indoleacetic acid oxidase in partially purified extracts from cotton is stimulated by small amounts of malate, succinate, fumarate, and other plant acids. The stimulation is apparently due to inhibition of catalase, which is detectable in certain preparations. The lag phase of indoleacetic acid oxidation by crude preparations is eliminated by steps in processing which conceivably either denatures or dilutes catalase, or concentrates inhibitors to catalase.

Effect of manganese toxicity on the indoleacetic Acid oxidase system of cotton.
The effect of substrate manganese on tissue manganese levels and activity of the indoleacetic acid (IAA)-oxidase system of cotton (Gossypium hirsutum, L.) was investigated. A sand culture technique was used with 1, 3, 9, 27 and 81 mg manganese (MnSO(4)) per liter nutrient solution applied in various experiments.The following relationships held for both long-term (126 days) and short-term (12-14...
متن کاملThe effect of water stress on indoleacetic Acid oxidase in pea plants.
Activity of indoleacetic acid oxidase was shown to increase following a period of water stress. Two fractions of indoleacetic acid oxidase were extracted from plant extracts. Similarly, two protein peaks (determined by ultraviolet absorption) were isolated. One peak, associated with an indoleacetic acid oxidase peak, increased following water stress. The second peak, not associated with extract...
متن کاملIAA Oxidase Inhibitors from Normal and Mutant Maize Plants.
Extracts of maize (Zea mays L.) plants contain substances which, in vitro, inhibit an indoleacetic acid (IAA) oxidase enzyme from maize. The extracts can be freed of inhibitors by dialysis or by passage through columns of polyvinylpyrrolidone powder. Inhibitor-free extracts contain an IAA oxidase enzyme which requires a phenolic co-factor and is stimulated by Mn(2+).IAA oxidase inhibitor and to...
متن کاملPeroxide Levels and the Activities of Catalase, Peroxidase, and Indoleacetic Acid Oxidase during and after Chilling Cucumber Seedlings.
The activities of catalase, peroxidase, indoleacetic acid (IAA) oxidase and peroxide levels in cucumber plants during and after chilling were determined. During 96 hours at 5 C and 85% relative humidity, catalase activity declined, IAA oxidase activity increased, and peroxide concentrations increased. Peroxidase activity was not affected by chilling. When chilled plants were returned to 25 C to...
متن کاملDistribution of Indoleacetic Acid Oxidase and Inhibitors in Light-Grown Cotton.
Extracts of green plant tissues exhibiting IAAoxidase activity characteristically contain inhibitors of the enzyme (4, 11). The high concentration of such inhibitors prompted the discoverers of IAAoxidase to suggest that the system does not function in green tissue (16). Later, Galston and Dalberg (6) found that in etiolated tissue the in vitro IAAoxidase activity increases with age or IAA trea...
