Project description:Rice genome contains three genes that encode for glutathione reductase (GR) viz., OsGR1, 2 and 3. GR is an important component of the anti-oxidative machinery of plant cells. GR2 down-regulated plants were produced by RNAi mediated down-regulation of GR2 (GR2-Ri). GR2-Ri plants were significantly smaller /reduced plant height compared to WT(Wild type), under control conditions. Microarray analysis was carried out to identify the genes which are differentially regulated in GR2-Ri compared to WT, respectively, under control conditions.

GR2 down-regulated plants were produced by RNAi mediated down-regulation of GR2 (GR2-Ri). GR2-Ri plants were significantly smaller and have significantly lower grain yield (grain number per panicle) compared to WT(Wild type), under control conditions. RNA-Seq analysis of panicles (differentiation stage) identified genes known to affect grain size to be differentially regulated in GR2-Ri compared to WT, respectively, under control conditions.

Project description:Knowledge of the stress-induced metabolic alterations in tolerant and sensitive plants is pivotal for identifying interesting traits that improve plant resilience toward unfavorable environmental conditions. This represents a hot topic area of plant science, particularly for crops, due to its implication in food security. Two rice varieties showing dissimilar resistance to salt, Baldo and Vialone Nano, have been studied to investigate the mechanisms underpinning tolerance toward salinity, and these studies have focused on the root system. A detailed analysis of the salt stress-dependent modulation of the redox network is here presented. The different phenotype observed after salt exposure in the two rice varieties is coherent with a differential regulation of cell-cycle progression and cell-death patterns observed at root level. Baldo, the tolerant variety, already showed a highly responsive antioxidative capacity in control conditions. Consistently, stressed Baldo plants showed a different pattern of H2O2 accumulation compared to Vialone Nano. Moreover, glutathione metabolism was finely modulated at transcriptional, post-transcriptional, and post-translational levels in Baldo. These results contribute to highlight the role of ROS and antioxidative pathways as a part of a complex redox network activated in rice toward salt stress.

Project description:Small heat shock proteins (sHSPs) have been thought to function as chaperones, protecting their targets from denaturation and aggregation when organisms are subjected to various biotic and abiotic stresses. We previously reported an sHSP from Oryza sativa (OsHSP20) that homodimerizes and forms granules within the cytoplasm but its function was unclear. We now show that OsHSP20 transcripts were significantly up-regulated by heat shock and high salinity but not by drought. A recombinant protein was purified and shown to inhibit the thermal aggregation of the mitochondrial malate dehydrogenase (MDH) enzyme in vitro, and this molecular chaperone activity suggested that OsHSP20 might be involved in stress resistance. Heterologous expression of OsHSP20 in Escherichia coli or Pichia pastoris cells enhanced heat and salt stress tolerance when compared with the control cultures. Transgenic rice plants constitutively overexpressing OsHSP20 and exposed to heat and salt treatments had longer roots and higher germination rates than those of control plants. A series of assays using its truncated mutants showed that its N-terminal arm plus the ACD domain was crucial for its homodimerization, molecular chaperone activity in vitro, and stress tolerance in vivo. The results supported the viewpoint that OsHSP20 could confer heat and salt tolerance by its molecular chaperone activity in different organisms and also provided a more thorough characterization of HSP20-mediated stress tolerance in O. sativa.

Project description:The JA deficient mutant (aoc) showed weaker symptoms than WT when both are exposed to salt. JAs signaling in WT, appeared then to impair salt tolerance and we were interested, through this transcriptomic approach, to highlight the JA-dependent component of the salt stress response that could explain the differential phenotype We report, for root and 2nd leaf, the compared transcriptomes of WT and aoc, before and at 3 different times (1 h, 6 h and 72 h) after salt exposure. The study reveals some key JA-regulated negative and positive effectors of salt stress tolerance in rice

Project description:Oxidative stress is harmful for organism and occurs when the cells exposed to superoxid, hydrogen peroxide and alkylhydroperoxides. In microorganism, the glutathione- and thioredoxin-dependent reduction systems are universal and play an important role in response to defending oxidative stress. The _-glutamylcysteine synthetase (_-GCS) is an essential enzyme to biosynthesize the tripeptide glutathione (GSH) in organism. Similarly, thioredoxin reductase is an important enzyme in thioredoxin-dependent reduction system. In Clostridium acetobutylicum, the _-glutamylcysteine synthetase (encoded by CAC1539, gcs) and thioredoxin reductase (encoded by CAC1548, trxB) were inactivated using ClosTron technology. The gcs mutant grew insufficiently and consumed less glucose in the phosphate-limited continuous culture and exhibited more sensitive to oxidative stress. The trxB mutant just exhibited lower growth rate and less glucose uptake in the solventogenic phase, compared to wild type. The DNA microarrays were performed to investigate the transcripome difference between wild type and the mutants. In gcs mutant, the genes related to chemotaxis and flagella biosynthesis proteins were induced significantly and in the trxB mutant, the sporulation genes were induced largely. Based on the phenotypes and transcriptome comparison results, the relationship between GSH- and Trx-dependent induction systems was discussed in Clostridium acetobutylicum.

Project description:Campeiostachys nutans, a dominant perennial grass in the Qinghai-Tibet Plateau, exhibits high tolerance to salt stress. The Salt Overly Sensitive (SOS) pathway is key to plant salt stress tolerance. However, the pivotal role of the SOS pathway in response to salt stress in C. nutans remains unknown. Here, we identified CnbHLH130 as a novel transcriptional activator of CnCBL10, directly binds to the G-box motif in the promoter. CnbHLH130 responds to salt stress and positively regulate salt tolerance in rice and C. nutans. Interestingly, we found CnCBL10 and CnCIPK4 interact with CnbHLH130 by a Y2H screening assay. The interactions were confirmed by split-luciferase complementation (split-LUC), Pull-down, Co-immunoprecipitation (Co-IP) and bimolecular fluorescence complementation (BiFC) assays. Moreover, CnbHLH130 enhanced the interaction between CnCBL10 and CnCIPK4, which further phosphorylate and activate Na+/H+ antiporter CnSOS1 to exclude excess cytosolic Na+ from cells in the shoots. Genetic evidence showed that CnCBL10, CnCIPK4 and CnbHLH130 coordinately regulates salt tolerance in plants. In summary, this study demonstrated that CnbHLH130 acts as a novel core component and transcriptional activator regulating CnCBL10-CnCIPK4 mediated SOS pathway, thus conferring to the salt tolerance in C. nutans. This work advanced our understandings of how an alpine plant greatly survived in the Qinghai-Tibet Plateau by concise regulation of the SOS pathway in response to salt stress.
