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:Two tobacco transgenic lines over-expressing grapevine polygalacturonase-inhibiting protein (Vvpgip1) vs. WT tobacco under normal growth 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:Comparative analysis of differentially expressed proteins in TaNRX1-2D overexpressing transgenic wheat, TaNRX1-2D-RNAi transgenic wheat, and wild-type wheat before and after salt stress conditions
Project description:we performed endosome proteome enrichment assay (Wang et al., 2023). Endosomes were enriched in the 100,000 g (P100) ultracentrifugation fraction from GFP-StKAKU4 transgenic N. benthamiana leaves during P. infestans infection.
Project description:Mesembryanthemum crystallinum (common ice plant) is a facultative halophyte species, which has adapted to extreme conditions. In this study, we cloned a McHB7 transcription factor gene from the ice plant. The expression of McHB7 was significantly induced by 500 mM NaCl and it reached the peak under salt treatment for 7 days. The McHB7 protein was targeted to the nucleus. Overexpression of McHB7 gene in ice plant leaves by Agrobacterium-mediated transformation led to 25 times more McHB7 transcripts than the non-transformed control wild type (WT). After 500 mM NaCl treatment for 7 days, SOD, POD activities and water content of the transgenic plants were significantly higher than WT, while MDA content was decreased in the transgenic plants. Proteomics results showed that a total of 1082 and 1072 proteins were profiled under control and salt treatment, respectively. 22 (2%) and 11 (1%) proteins were uniquely identified under control and salt stress conditions, respectively. Among these 11 proteins, 7 were increased and 4 were decreased. Most identified proteins involved in the processes of regulation of biological, transporter and catalytic activity, biosynthesis of secondary metabolties and response to stimulus were significantly increased in the McHB7 overexpression ice plants under high salinity. All the results demonstrate that the McHB7 transcription factor plays a positive role in improving plant salt tolerance.
