“…In contrast, the gua iacol peroxidase activity was higher under the same conditions. Of note, the higher activity of the studied antioxidant enzymes, which was due to JA influence, was also observed in other plants [14,22,23]. As was found, JA and methyl jasmonate can induce new molecular species of SOD and peroxidase in wheat and castor bean leaves [22,23].…”

The effects of exogenous jasmonic acid (JA) on antioxidant enzymes in four week old leaves of wild type Arabidopsis thaliana L. (Columbia 0) and jin1 (jasmonate insensitive 1) mutant plants with defective jasmonate signaling were investigated under normal conditions and under salt stress (200 mM NaCl, 24 h). The wild type plants responded to JA by an increase in the activities of Cu/Zn superoxide dismutase, catalase, and guaiacol peroxidase, while there was no change in the case of the mutant plants. In response to the salt stress of both the wild type and mutant genotypes, the activities of superoxide dismutase, catalase, and guaiacol per oxidase were unchanged, decreased, and increased, respectively. The JA treated wild type plants showed the highest activity of all three enzymes as compared with the mutant plants. Salinity caused a decrease in chloro phyll content in the wild type and jin1 plants. Preliminary JA treatment of the Col 0 plants resulted in a normal content of photosynthetic pigments after the salt stress, while the positive JA effect was insignificant in the jin1 mutants. It was concluded that the MYC2/JIN1 protein is involved in the JA signal transduction and plant adaptation to salt stress.

Activities of antioxidant enzymes and the osmolyte contents in seedlings of winter rye (Secale cereale L.), soft (Triticum aestivum L.) and durum (T. durum L.) wheat, and barley (Hordeum vulgare L.) grown at 20°C (control) or after 7 day cold hardening at 2°C and/or 5 hour freezing at -6°C were investi gated. It was found that nonhardened rye seedlings differed from those of other cereals by their ability to sur vival after freezing at -6°C and higher activity of guaiacol peroxidase (GPO) and high content of proline. Hardening induced the increase in the frost tolerance of all cereals under study, and the resistance of rye and soft wheat was found to be significantly higher than that of durum wheat and barley. Rye and soft wheat exhib ited more profound tolerance to oxidative damages as well, and it was expressed in lesser increase in the MDA content after freezing. In the course of hardening, detectable increase in the activities of GPO and catalase (CAT), as well as the contents of proline and soluble carbohydrates, was observed in seedlings of all cereals under study. In barley, the activity of superoxide dismutase (SOD) increased to the highest extent under these conditions. After freezing of both hardened and nonhardened seedlings, higher activities of all tested antiox idant enzymes were revealed in rye and soft wheat as compared to those in durum wheat and barley. In this case, hardened rye and soft wheat seedlings after freezing displayed increased content of proline. All these results lead to the conclusion that the high content of proline and activity of GPO observed in rye seedlings may determine their increased constitutive frost tolerance, whereas high tolerance of hardened soft wheat seedlings is primarily associated with accumulation of low molecular weight protectors, such as sugars and proline, and, to some extent, with the increased activity of antioxidant enzymes.Abbreviations: GPO-guiaicol peroxidase; CAT-catalase; SOD-superoxide dismutase; TBA-2 thiobarbituric acid.
