ThERF1 regulates its target genes via binding a novel cis-acting element in response to salt stress

ABSTRACT: To reveal the regulatory network of ThERF1 in response to abiotic stress, we have employed an Agilent Arabidopsis gene expression microarray to study the expression profile changes between Wild-type and transgenic plants overexpressing ThERF1 under salt stress. A total of 154 and 307 differentially expressed genes with p-value < 0.05 and ≥ 2-fold change were significantly up- and down- regulated in ThERF1-transformed plants under salt stress treatment.

ThERF1 regulates its target genes via binding a novel cis-acting element in response to salt stress

Project description:To reveal the regulatory network of ThERF1 in response to abiotic stress, we have employed an Agilent Arabidopsis gene expression microarray to study the expression profile changes between Wild-type and transgenic plants overexpressing ThERF1 under salt stress. A total of 154 and 307 differentially expressed genes with p-value < 0.05 and M-bM-^IM-% 2-fold change were significantly up- and down- regulated in ThERF1-transformed plants under salt stress treatment. Four-week-old seedlings of Wild-type and ThERF1-transformed Arabidopsis plants treated with 120 mM NaCl for 6 h were immediately harvested for RNA isolation. The Agilent Arabidopsis (V4) gene expression microarray (4M-CM-^W 44K, Design ID: 021169) was employed to compare the gene expression profiles of Wild-type and transgenic plants with three independent biological replicates.

On salt stress PLETHORA signalling maintains root meristems

Project description:Salinity represses plant root growth, resulting in reduced biomass of agricultural plants. Little is known about how plants maintain root growth and development to counteract salt stress. SOS2-mediated PLT1/2 phosphorylation stabilizes PLT1/2, which is critical for root apical meristem maintenance under salt stress.

Expression data of Frankia CcI3 in plant root nodules under salt stress

Project description:Purpose: To compare RNASeq data of Frankia CcI3 in plants under salt stress. Casuarina glauca root nodules infected with Frankia CcI3 were exposed to either no salt or 100 mM NaCl for 21 days. RNA-seq analysis provided insight into how the sybiont responds to salt stress.

Salt stress responses of Arabidopsis thaliana and Eutrema salsugineum (Thellungiella salsuginea)

Project description:Arabidopsis thaliana is a glycophyte with a low salt tolerance, while Eutrema is a halophyte with a very high salt tolerance. To elucidate the transcriptional basis of this difference, we performed hydroponis culture experiments where we grew plants under control conditions (25 mM NaCl) or under salt stress (200 mM NaCl for both species, 500 mM for Eutrema). Salt concentration was increased for the stress treatments by increments of 50 mM per day (25 mM on the first day). Plants were grown at the final NaCl concentration for an additional week, when rosettes were harvested for RNA isolation.Expression patterns were compared between treatments and between species.

Gene expression profiling of Bruguiera gymnorhiza under salt stress

Project description:To identify key genes in the regulation of salt tolerance in the mangrove plant Bruguiera gymnorhiza, the transcriptome profiling under salt stress was carried out. Main roots and lateral roots were collected from the mangrove plants at 0, 1, 3, 6, 12 and 24 h, 3 6 and 12 days after NaCl-treatment. Keywords: time course, stress response, root type comparison

Gene expression signatures of transgenic and wild-type tobaccos under normal or salt-stress conditions

Project description:To understand the effect of salt stress on CbFAD3 transgenic and wild-type tobaccos, we have employed whole genome microarray expression profiling of transgenic and wild-type plants under normal or salt-stress conditons, respectively. We also found the founction of CbFAD3 gene on tobaccos through comparing these data.

Transcriptome analysis provides insights into the mechanism of salt tolerance in rice colonized by arbuscular mycorrhizal fungi

Project description:Although previous studies have addressed the possible benefits of arbuscular mycorrhizal (AM) symbiosis for rice plants under salinity, the underlying molecular mechanisms are still unclear. Here, we showed that rice colonized with AM fungi had better growth performance and higher K+/Na+ ratio under salt stress. Differentially expressed genes (DEGs) responding to AM symbiosis especially under salt stress were obtained from RNA sequencing. AM-regulated DEGs in cell wall modification and peroxidases categories were mainly upregulated in shoots, suggesting AM symbiosis might assist in relaxing the cell wall and scavenging reactive oxygen species (ROS). AM symbiosis indeed improved ROS scavenging capacity in rice shoots under salt stress. In addition, genes involved in Calvin cycle and terpenoid synthesis were enhanced by AM symbiosis in shoots and roots under salt stress, respectively. AM-upregulated cation transporters and aquaporin in both shoots and roots were highlighted. Strikingly, “protein tyrosine kinase activity” subcategory was the most significantly over-represented GO term among all AM-upregulated and downregulated DEGs in both shoots and roots, highlighting the importance of kinase on AM-enhanced salinity tolerance. Overall, our results from the transcriptomic analyses indicate that AM symbiosis uses a multipronged approach to help plants achieve salt stress tolerance.
