cDNA cloning and sequence characterization of an ascorbate peroxidase from marine red alga Porphyra yezoensis;

The analysis of peroxidase isoenzyme electrophoresis and activity of ascorbate peroxidase (ASP) in Scutellaria baicalensis Georgi;

With the pH value of acid rain declining, the activities of superoxide dismutase(SOD) and ascorbate peroxidase(AsA-POD), the contents of glutathione(GSH) and ascorbic acid(AsA) in the chloroplasts of longan leaves decreased while the malondialdedyde(MDA) content increased.

Ascorbic acid (AsA) contents,together with the activities of L-galactono-1,4-lactone dehydrogenase (GalLDH),ascorbic acid oxidase (AAO),ascorbate peroxidase (APX),monodehydroascorbate reductase (MDAR) and dehydroascorbate reductase (DHAR) were measured with non-heading Chinese cabbage varieties,Changzhouwutacai,Aijiaohuang and Erqing during plant development.

Although cell wall digestion in enzyme solution induced an increase in superoxide dismutase (SOD) and ascorbate peroxidase (APX) activities in isolated protoplasts from cell suspension of Astragalus adsurgens, a distinct fall was observed for APX activity in cultured protoplasts accompanied by a further increase in SOD activity (Figs.

In this experiment,superoxide dismutase (SOD) and/or ascorbate peroxidase (APX) activities in leaves of SOD-or APX-gene transformed tobacco (Nicotiana tabacum L.

Cloning and Expression Analysis of An APX Gene from Betula platyphylla

4), and detecting activi- ties of superoxide dismutase (SOD) and ascorbate peroxidase (APX), the effects of chilling stress under weak light on functions of photosystem I (PSI) and photosystem II (PSII) in leaves of a wild type soybean variety ‘ZYD00019’ and a cultivar soybean variety ‘Zaoshu No.

Three wheat varieties with different aluminum tolerances were used to study ascorbic acid contents, and ascorbic oxidase and APX activities in root apoplast and symplasm of wheat seedling under aluminum stress.

AsA pretreatment significantly enhanced AsA content and the activity of ascorbic acid peroxidase (APX) in maize seedlings under normal culture condition.

After the treatment on the dry seed or germinatlve seed of corn, wheat or mung beau with the specified electromagnetic wave, add adequate water and put in under the condition of 27℃ for culture, then analyse the specimen of th bud or the seeding reqularly for the activiation of ascorbic acid peroxidase and the contents of GSH and ascorbic acid.
