“…Reduction of O • 2 − into H 2 O 2 is primarily conducted by SOD isoenzymes (Fridovich, ; Gill & Tuteja, ). In rice, the SOD gene family contains fifteen members, including four CSDs, four SODs and another seven related chaperones including CCSD (Nath et al ., ). Among the 15 members, the four CSDs were identified as CSD1 , CSD2 , CSD3 and CSD4 (Fig.…”

Osa‐miR398b boosts H₂O₂ production and rice blast disease‐resistance via multiple superoxide dismutases

Summary mi RNA s contribute to plant resistance against pathogens. Previously, we found that the function of miR398b in immunity in rice differs from that in Arabidopsis. However, the underlying mechanisms are unclear. In this study, we characterized the mutants of miR398b target genes and demonstrated that multiple superoxide dismutase genes contribute to miR398b‐regulated rice immunity against the blast fungus Magnaporthe oryzae . Out of the four target genes of miR398b, mutations in Cu/Zn‐Superoxidase Dismutase1 ( CSD 1 ), CSD 2 and Os11g09780 ( Superoxide DismutaseX , SODX ) led to enhanced resistance to M. oryzae and increased hydrogen peroxide (H 2 O 2 ) accumulation. By contrast, mutations in Copper Chaperone for Superoxide Dismutase ( CCSD ) resulted in enhanced susceptibility. Biochemical studies revealed that csd1 , csd2 and sodx displayed altered expression of CSD s and other superoxide dismutase ( SOD ) family members, leading to increased total SOD enzyme activity that positively contributed to higher H 2 O 2 production. By contrast, the ccsd mutant showed CSD protein deletion, resulting in decreased CSD and total SOD enzyme activity. Our results demonstrate the roles of different SOD s in miR398b‐regulated resistance to rice blast disease, and uncover an integrative regulatory network in which miR398b boosts total SOD activity to upregulate H 2 O 2 concentration and thereby improve disease resistance.

“…Fe-SOD localizes to chloroplast and is sensitive to H 2 O 2 , while Mn-SOD located both in mitochondria and peroxisomes and resistant to H 2 O 2 and Cu-Zn SOD localizes to chloroplast and cytoplasm and is sensitive to H 2 O 2 (Gill and Tuteja 2010). Using in silico approach, Nath et al (2014) identified one SOD copper chaperone gene and other seven SOD isoforms in rice including two cytosolic Cu-Zn SODs, one putative Cu-Zn SOD-like, one plastidic SOD, two Fe-SODs and one Mn-SOD. These isoforms display differential expression during different developmental stages implicating specific role played by each of the gene.…”

Reactive Oxygen Species and Antioxidant Systems in Plants: Role and Regulation Under Abiotic Stress

View full text Add to dashboard Cite

All environmental cues lead to develop secondary stress conditions like osmotic and oxidative stress conditions that reduces average crop yields by more than 50% every year. The univalent reduction of molecular oxygen (O 2) in metabolic reactions consequently produces superoxide anions (O 2 •À) and other reactive oxygen species (ROS) ubiquitously in all compartments of the cell that disturbs redox potential and causes threat to cellular organelles. The production of ROS further increases under stress conditions and especially in combination with high light intensity. Plants have evolved different strategies to minimize the accumulation of excess ROS like avoidance mechanisms such as physiological adaptation, efficient photosystems such as C4 or CAM metabolism and scavenging mechanisms through production of antioxidants and antioxidative enzymes. Ascorbate-glutathione pathway plays an important role in detoxifying excess ROS in plant cells, which includes superoxide dismutase (SOD) and ascorbate peroxidase (APX) in detoxifying O 2 •À radical and hydrogen peroxide (H 2 O 2

In the present study we investigated the seasonal pattern of activity of antioxidant enzymes such as superoxide dismutase (SOD) catalase (CAT) ascorbate peroxidase (APX), guaiacol peroxidase (POD) and syringaldazine peroxidase (SPOD) as well as the total protein concentration in the European mistletoe (Viscum album L. subsp. album). We studied mistletoe leaves that grew on the selected tree species in different parts the city of Lodz, exposed to a greater or lesser extent to the nitrogen dioxide. Sampling campaigns were conducted during the growing season 2013 in early May (at the beginning of the growing season) and in November (at the end of the growing season). We showed considerable seasonal variations of antioxidant enzymatic activity and total protein concentrations for all the samples studied. The test parameters varied depending on the host plants exposition to pollution with nitrogen dioxide. The changes in enzymatic activity did not depend on the host plants. In mistletoe leaves greater changes of SOD activity and total protein concentration were observed in autumn. There is correlation between the level of nitrogen dioxide in atmosphere and activities the enzymes. SOD activity was signifi cantly higher in autumn when the host plants were defoliated. Increased CAT activity was observed in late spring. We demonstrated the positive correlation between changes in enzyme activities and the progress of growing season. Increased activities of POD, CAT and APX to a limited extent depended on the place of growing and exposition to air pollution. In late spring activity of the enzymes did not signifi cant grow because of the protective umbrella from host plant leaves preventing the access of nitrogen dioxide to mistletoe. The higher SOD activity in mistletoe is a consequence of oxidative stress causes by nitrogen dioxides evidently observed in the city center. The test parameters, mainly the activity of SOD, can be used in the future as markers of the
