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.

Project description:Transcriptome sequencing of ScDREB5 transgenic Arabidopsis and wild type under normal and salt stress conditions
Project description:Nicotiana benthamiana is a widely used organism for expression of foreign proteins. To increase protein abundance, overexpression promoters have been developed. However, several proteins cause negative effects on plant growth and development when they are overexpressed. Therefore, overexpression promoters cannot be widely used to generate transgenic plants that produce foreign proteins. In this study, we tried to find stress-inducible promoters which specifically express downstream genes when plants were exposed to stress conditions. By RNA-sequencing analysis of heat- and wound-treated plants, we found that NbHSP20 promoters can be used as a heat-inducible promoters to express foreign proteins in N. benthamiana.

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 ≥ 2-fold change were significantly up- and down- regulated in ThERF1-transformed plants under salt stress treatment.

Project description:Dongxiang wild rice (Oryza rufipogon Griff.) is the progenitor of cultivated rice (Oryza sativa L.) and is well known for its superior level of tolerance against cold, drought and diseases. To date, however, little is known about the salt-tolerant character of Dongxiang wild rice. To elucidate the molecular genetic mechanisms of salt-stress tolerance in Dongxiang wild rice, the Illumina HiSeq 2000 platform was used to analyze the transcriptome profiles of the leaves and roots at the seedling stage under salt stress compared with those under normal conditions. The analysis results for the sequencing data showed that 6,867 transcripts were differentially expressed in the leaves (2,216 up-regulated and 4,651 down-regulated) and 4,988 transcripts in the roots (3,105 up-regulated and 1,883 down-regulated). Among these differentially expressed genes, the detection of many transcription factor genes demonstrated that multiple regulatory pathways were involved in salt stress tolerance. In addition, the differentially expressed genes were compared with the previous RNA-Seq analysis of salt-stress responses in cultivated rice Nipponbare, indicating the possible specific molecular mechanisms of salt-stress responses for Dongxiang wild rice. A large number of the salt-inducible genes identified in this study were co-localized onto fine-mapped salt-tolerance-related quantitative trait loci, providing candidates for gene cloning and elucidation of molecular mechanisms responsible for salt-stress tolerance in rice.
