Project description:Here, we investigated the function of the plant-specific SR protein RS33 in pre-mRNA splicing regulation and abiotic stress responses in rice. The loss-of-function mutant, rs33, showed increased sensitivity to salt and low-temperature stress. Genome-wide analyses of gene expression and splicing in seedlings subjected to these stresses identified multiple splice isoforms from stress-responsive genes dependent on RS33. The number of RS33-regulated genes is much higher under low-temperature stress as compared to salt stress. Our results suggest that this plant-specific splicing factor plays crucial and distinct roles during plant adaptation to abiotic stresses.

Project description:We investigated the function of the plant-specific SR protein SC106 in pre-mRNA splicing regulation and abiotic stress responses in rice. The loss-of-function mutant, SC106, showed increased sensitivity to salt. We performed genome-wide analyses of gene expression and splicing in seedlings subjected to salt stress and identified multiple splice isoforms from stress-responsive genes dependent on SC106.

Project description:This research was undertaken to investigate the global role of inositol phosphorylceramide synthase (IPCS) activity in plants and reveal its potential as a herbicide target. The non-mammalian enzyme is a key component in the plant sphingolipid biosynthetic pathway and is shown here to be a possible herbicide target. RNA-Seq analyses demonstrated that over-expression of inositol phosphorylceramide synthase isoforms AtIPCS1, 2 or 3 in Arabidopsis thaliana resulted in the down-regulation of genes involved in plant response to pathogens. In addition, genes associated with the abiotic stress response to salinity, cold and drought were found to be similarly down-regulated. Detailed analyses of transgenic lines over-expressing AtIPCS1-3 at various levels revealed that the degree of down-regulation is specifically correlated with the level of IPCS expression. Singular enrichment analysis of these down-regulated genes showed that AtIPCS1-3 expression affects biological signaling pathways involved in plant response to biotic and abiotic stress. The up-regulation of genes involved in photosynthesis and lipid localization was also observed in the over-expressing lines.

Project description:For identification of genes up-regulated in abiotic stress (drought, high salinity, low temperature and ABA) treated rice, total RNA (100 μg) was prepared from root tissues of 14-d-old rice seedlings (Oryza sativa cv Nakdong) grown under normal growth conditions. For the high salinity and ABA treatments, the 14-d-old seedlings were transferred to a nutrient solution containing 400 mM NaCl or 100 μM ABA for 2 h in the greenhouse under continuous light of approximately 1000 μmol m-2 s -1. For drought treatment, 14-d-old seedlings were air-dried for 2 h also under continuous light of approximately 1000 μmol m-2 s -1. For low temperature treatments, 14-d-old seedlings were exposed at 4°C in a cold chamber for 6 h under continuous light of 150 μmol m-2 s -1.

Project description:Although abscisic acid (ABA) is an important hormone that regulates seed dormancy, stomatal closure, plant development, as well as responses to environmental stimuli, the physiological mechanisms of ABA response to multiple stress in rice remain poorly understood. In the ABA biosynthetic pathway, 9-cis-epoxycarotenoid dioxygenase (NCED) is the key rate-limiting enzyme. Here, we report important functions of OsNCED3 in multi-abiotic stress tolerance in rice. The OsNCED3 is constitutively expressed in various tissues under normal condition, Its expression is highly induced by NaCl, PEG, and H2O2 stress, suggesting the roles for OsNCED3 in response to the multi-abiotic stress tolerance in rice. Compared with wild-type plants, nced3 mutants had earlier seed germination, longer post-germination seedling growth, increased sensitivity to water stress and H2O2 stress and increased stomata aperture under water stress and delayed leaf senescence. Further analysis found that nced3 mutants contained lower ABA content compared with wild-type plants, overexpression of OsNCED3 in transgenic plants could enhance water stress tolerance, promote leaf senescence and increase ABA content. We conclude that OsNCED3 mediates seed dormancy, plant growth, abiotic stress tolerance, and leaf senescence by regulating ABA biosynthesis in rice; and may provide a new strategy for improving the quality of crop.

Project description:BackgroundConstitutive and alternative splicing of pre-mRNAs from multiexonic genes controls the diversity of the proteome; these precisely regulated processes also fine-tune responses to cues related to growth, development, and stresses. Small-molecule inhibitors that perturb splicing provide invaluable tools for use as chemical probes to uncover the molecular underpinnings of splicing regulation and as potential anticancer compounds.ResultsHere, we show that herboxidiene (GEX1A) inhibits both constitutive and alternative splicing. Moreover, GEX1A activates genome-wide transcriptional patterns involved in abiotic stress responses in plants. GEX1A treatment -activated ABA-inducible promoters, and led to stomatal closure. Interestingly, GEX1A and pladienolide B (PB) elicited similar cellular changes, including alterations in the patterns of transcription and splicing, suggesting that these compounds might target the same spliceosome complex in plant cells.ConclusionsOur study establishes GEX1A as a potent splicing inhibitor in plants that can be used to probe the assembly, dynamics, and molecular functions of the spliceosome and to study the interplay between splicing stress and abiotic stresses, as well as having potential biotechnological applications.

Project description:In the present study, we found that Nipponbare and IAC1131 behave equivalently in response to multiple abiotic stress, which included simultaneous application of drought, salt and temperature stress. At the level of molecular analysis by isotopic labelling quantitative proteomics, 6215 proteins were reproducibly identified and quantified across the two genotypes and three time points sampled. Heat shock proteins, late embryogenesis abundant proteins, and photosynthesis-related proteins were all found to be differentially abundant in response to stress treatments in both Nipponbare and IAC1131.

Project description:Plants can perceive environmental changes and respond to external stressors. Here, we show that OsNAC2, a member of the NAC transcription factor family, was strongly induced by ABA and osmotic stressors such as drought and high salt. With reduced yields under drought conditions at the flowering stage, OsNAC2 overexpression lines had lower resistance to high salt and drought conditions. RNAi plants showed enhanced tolerance to high salinity and drought stress at both the vegetative and flowering stages. Furthermore, RNAi plants had improved yields after drought stress. A microarray assay indicated that many ABA-dependent stress-related genes were down-regulated in OsNAC2 overexpression lines. We further confirmed that OsNAC2 directly binds the promoters of LATE EMBRYOGENESIS ABUNDANT 3 (OsLEA3) and Stress-Activated Protein Kinases 1 (OsSAPK1), two marker genes in the abiotic stress and ABA response pathways, respectively. Our results suggest that in rice OsNAC2 regulates both abiotic stress responses and ABA-mediated responses, and acts at the junction between the ABA and abiotic stress pathways.

Project description:In many potato cultivation regions, production is constrained by abiotic stresses such as drought and high temperatures which are often present in combination. We aimed to identify key mechanisms and processes underlying single and combined abiotic stress tolerance by a comparative analysis of tolerant and susceptible cultivars. Physiological data supported cultivars Desiree and Unica as being abiotic stress tolerant, while Agria and Russett Burbank were stress susceptible. This was indicated by the stronger impact of abiotic stress on photosynthetic carbon assimilation in the susceptible cultivars. Similarly, susceptible cultivars exhibited a lower leaf transpiration rate following stress, particularly combined heat and drought stress. Transcript profiles using microarrays were highly divergent both between genotypes and following the application of stress treatments. However, relatively few transcripts or metabolites exhibited genotype specific responses to abiotic stress treatment. Furthermore, apart from a decrease in the abundance of transcripts associated with PSII, particularly the light harvesting complex in both Desiree and Unica, there were very few changes that were consistent across stress susceptible or stress tolerant genotypes following stress treatment.
