- Key message
- Furthermore, noe1 resulted in an increase of hydrogen peroxide (H(2)O(2)) in the leaves, which consequently promoted NO production via the activation of nitrate reductase
- Here, we report the identification of an NO accumulation mutant, nitric oxide excess1 (noe1), in rice (Oryza sativa), the isolation of the corresponding gene, and the analysis of its role in NO-mediated leaf cell death
- The removal of excess NO reduced cell death in both leaves and suspension cultures derived from noe1 plants, implicating NO as an important endogenous mediator of H(2)O(2)-induced leaf cell death
- Reduction of intracellular S-nitrosothiol (SNO) levels, generated by overexpression of rice S-nitrosoglutathione reductase gene (GSNOR1), which regulates global levels of protein S-nitrosylation, alleviated leaf cell death in noe1 plants
- Thus, S-nitrosylation was also involved in light-dependent leaf cell death in noe1
- NO targets identified only in noe1 plants included glyceraldehyde 3-phosphate dehydrogenase and thioredoxin, which have been reported to be involved in S-nitrosylation-regulated cell death in animals
- Taken together, the current study results revealed a novel role of OsCATC in starch metabolism in addition to validating previously studied functions of CATs
- Rice catalase OsCATC is degraded by E3 ligase APIP6 to negatively regulate immunity
- Connection
- OsCATB, OsCATC~NOE1~OsCAT3, ABA controls H2O2 accumulation through the induction of OsCATB in rice leaves under water stress, Water stress inhibited the expression of CATA and CATC but substantially enhanced the expression of CATB
- OsCATB, OsCATC~NOE1~OsCAT3, ABA controls H2O2 accumulation through the induction of OsCATB in rice leaves under water stress, Exogenously applied ABA promoted the expression of CATB also and inhibited the expression of CATC in a concentration-dependent manner
- OsCATB, OsCATC~NOE1~OsCAT3, ABA controls H2O2 accumulation through the induction of OsCATB in rice leaves under water stress, When ABA production was inhibited by using ABA biosynthesis inhibitors nordihydroguaiaretic acid and tungstate, expression of CATB was also subdued while CATC was enhanced under the water stress
- OsCATA, OsCATC~NOE1~OsCAT3, ABA controls H2O2 accumulation through the induction of OsCATB in rice leaves under water stress, Water stress inhibited the expression of CATA and CATC but substantially enhanced the expression of CATB
- APIP6, OsCATC~NOE1~OsCAT3, Rice catalase OsCATC is degraded by E3 ligase APIP6 to negatively regulate immunity, Rice catalase OsCATC is degraded by E3 ligase APIP6 to negatively regulate immunity
- OsCATC~NOE1~OsCAT3, RHS1, A Novel RHS1 Locus in Rice Attributes Seed-Pod Shattering by the Regulation of Endogenous S-Nitrosothiols., Interestingly noe1, a rice mutant with high SNO levels, exhibited low seed shattering, whereas rhs1 resulted in low SNO levels with high seed shattering
- OsCATC~NOE1~OsCAT3, OsEDS1, ENHANCED DISEASE SUSCEPTIBILITY 1 promotes hydrogen peroxide scavenging to enhance rice thermotolerance., Rice CATALASE C (OsCATC), whose activity is promoted by OsEDS1, degrades H2O2 to activate rice heat stress tolerance
- OsCATC~NOE1~OsCAT3, WFSL1~STRIPE3~WSL214, WSL214 negatively regulates ROS accumulation and pathogen defense response in rice., First, WSL214 increased the expression of the catalase gene OsCATC, making the intracellular ROS scavenging enzyme more active
