Project description:St (common potato) is a freezing sensitive species unable to cold acclimate. The close wild relative Sc is freezing tolerant and able to cold acclimate. Here we compare the cold transcriptome of these two species with different levels of freezing tolerance. We also identify the putative CBF regulons by comparing the transcriptomes of wild type plants with that of 35S::AtCBF3 transgenic lines in both species.

Here we compare the cold transcriptome of these two species with different levels of freezing tolerance. We also identify the putative CBF regulons by comparing the transcriptomes of wild type plants with that of 35S::AtCBF3 transgenic lines in both species. Plants were grown in 16:8 photoperiod. Eight hours after dawn, plants were either transfered to cold or kept in the warn. Wild type S. tuberosum and S. commersonii were grown at 2oC for 2h, 24h and 7 days. Wild type plants grown under warm temperatures for 2h was used as control for 2h cold samples; wild type warm grown plants for 24h were used as controls for 24h and 7 days cold samples. Under warm conditions, S. commersonii 35S::AtCBF3 lines were compared to S. commersonii wild type plants (same thing was done for S. tuberosum).

Project description:Potato plants are sensitive to multiple abiotic stresses such as drought, low temperature and high light. We analyzed the transcriptome of WT potato plants as well as that of transgenic potato plants expressing the Arabidopsis stress related transcription factor CBF1 that confers tolerance to multiple stresses. Wild type and AtCBF1OX transgenic potato plants were exposed to low temperature, high light, drought or kept under control conditions as described below in detail, and transcriptional changes induced by the different stresses were analyzed.

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:Arabidopsis thaliana: transgenic plants vs wild type

Project description:Purpose: Trichomes, developing from the epidermis of nearly all terrestrial plants, provide good structural resistance against insect herbivores and an excellent model for studying the molecular mechanisms underlying cell fate determination. Regulation of trichomes in Rosids has been well characterized. However, little is known about the cell proliferation molecular processes during multicellular trichome formation in Asterids. Methods: The transcriptomes of between Wov transgenic and wild-type tobacco by RNA-seq analysis were evaluated using the Illumina HiSeq™ 2000 sequencing platform. Raw sequences were filtered and the resulting sets of clean reads were used for the following analysis by Tophat and DEGseq software. qRT–PCR validation was performed using SYBR Green assays. Results: In this study, we identified two point mutations in a novel allele (Wov) at Wo locus. Ectopic expression of Wov in tobacco and potato induces much more trichome formation than wild type. To gain new insights into the underlying mechanisms during the processes of these trichomes formation, we compared the gene expression profiles between Wov transgenic and wild-type tobacco by RNA-seq analysis. A total of 544 co-DEGs were detected between transgenic and wild-type tobacco. Functional assignments of the co-DEGs indicated that 33 reliable pathways are altered in transgenic tobacco plants. The most noticeable pathways are fatty acid metabolism, amino acid biosynthesis and metabolism, and plant hormone signal transduction. Results suggest that these enhanced processes are critical for the cell proliferation during multicellular trichome formation in transgenic plants. In addition, the transcriptional levels of homologues of trichome regulators in Rosids were not significantly changed, whereas homologues of genes (Wo and SlCycB2) in Asterids were significantly upregulated in Wov transgenic tobacco plants. Conclusions: This study presents a global picture of the gene expression changes induced by Wov- gene in tobacco. And the results provided us new insight into the molecular processes controlling multicellular formation in tobacco. Furthermore, we inferred that trichomes in solanaceous species might share a common network. The transcriptomes of between Wov transgenic and wild-type tobacco by RNA-seq analysis were evaluated, in duplicate, using the Illumina sequencing platform.
