To study the effects of water stress on compatibility metabolites and the antioxidant enzyme activities of wheat variety trial a factorial experiment was conducted in a completely randomized design in 1393. The experiment consisted of three levels of stress (85, 60 and 35% of field capacity) and five varieties of wheat (Orom, Zarea, Mihan, ZSZOBKAYKA, JS3l7G217,) Analysis of variance showed, Pr...
Catalase-peroxidases belong to Class I of the plant, fungal, bacterial peroxidase superfamily, together with yeast cytochrome c peroxidase and ascorbate peroxidases. Obviously these bifunctional enzymes arose via gene duplication of an ancestral hydroperoxidase. A 230-residues long homologous region exists in all eukaryotic members of Class I, which is present twice in both prokaryotic and arch...
Hemp (Cannabis sativa L.) is a species considered as having one of the most complicated mechanisms of sex determination. Peroxidase and esterase isoenzymes in leaves of the two sexual phenotypes of hemp were studied. Significant differences in isoperoxidase and isoesterase patterns were found between male and female plants, both in the number and stain intensity of bands. For both esterase and ...
Antioxidant enzymes play an important role in plant defense against pathogenic agents. Following the identification of the pathogen, plants produce active oxygen species (ROS) as one of their first defense responses. To maintain the balance of ROS levels and prevent their harmful effects, plants produce antioxidant peroxidase (POX), catalase (CAT), ascorbate peroxidase (APX) and superoxide dism...
