Project description:Cycling Dof Factor (CDF) transcription factors have been implicated in different aspects of plant growth and development. In Arabidopsis and tomato, two members of this family CDF1 and CDF3 have recently been associated with the regulation of primary metabolism and abiotic stress responses, but their roles in crop production under open field conditions remain unknown. In this study, we compared growth and tuber yield and composition of wild-type (WT) potato plants and plants ectopically expressing the CDF1/3 genes from Arabidopsis under the control of the 35S promoter cultured under growth chamber and open field conditions. In growth chambers, the 35S::AtCDF1 and 35S::AtCDF3 potato plants showed higher than WT biomass production and tuber yield. Under field conditions, 35S::AtCDF1 plants showed significant increases in tuber yield with a significant increase in tuber weight, whereas 35S::AtCDF3 plants showed no significant changes in yield, but produced more than WT number of tubers. Metabolomic analysis revealed that tubers of 35S::AtCDF1 plants cultured under open field conditions accumulated higher levels of glucose, starch and amino acids than WT tubers. Comparative proteomic analysis of tubers of 35S::AtCDF1 and control plants cultured under open field revealed that these changes can be accounted for by changes in the expression of proteins involved in energy production and different aspects of C and N metabolism. Results from this study advance our collective understanding of the role of CDFs and are of interest to improve yield and breeding of crop plants

Project description:AtACINUS protein is involved in regulation of alternative transcription and splicing(AS). Identifying interaction partners and protein complex compositions for AtACINUS can produce valuable information on the mechanisms by which they regulate transcription and AS, as well as post-translational modifications on AtACINUS. A homozygous 35S::AtACINUS-GFP/acinus-2 plant was selected for similar protein expression level to the endogenous AtACINUS protein of wild-type plants using a native α-AtACINUS antibody. We isolated putative AtACINUS interaction partners from young Arabidopsis seedlings using the native α-AtACINUS antibody. Plants expressing TAP-GFP under 35S promoter were used as controls.

Project description:Transcriptional profiling of Arabidopsis thaliana, comparing control wild-type (ecotype Wassilewskija, Ws) leaves with leaves from transgenic plants overexpressing the transcription factor RAP2.6L under control of the cauliflower mosaic virus 35S promoter (RAP2.6L-OX; this line was originally described in Krishnaswamy et al (2010)).

Project description:affy_meja_arabidopsis - We want to determine if the presence of C2 modifies the cell transcriptome and its response to methyl jasmonate. Comparison of control lines and transgenic lines expressing C2 in basal conditions and after treatment with 50uM MeJA for 10 hours. C2 lines are expressing geminivirus C2 under a 35S promoter. PR1-LUC have a luciferase transgene under the control of the promoter of PR1; since the plants are not induced, these are the control plants (resistant to kanamycin, but not expressing anything else) Keywords: gene knock in (transgenic),treated vs untreated comparison

Project description:A novel cold-inducible GSK3/Shaggy-like kinase cDNA (TaSK5) was isolated from winter wheat by a macroarray-based differential screening approach. Sequence analysis of TaSK5 revealed high similarity to Arabidopsis subgroup I GSK3/Shaggy-like kinases ASK-alpha, ASK-gamma and ASK-epsilon. Transgenic Arabidopsis plants overexpressing TaSK5 cDNA under the control of CaMV 35S promoter showed enhanced tolerance to salt and drought stresses. In contrast, the tolerance of the transgenic plants to freezing stress was not altered. To identify genes which are differentially regulated in the 35S:TaSK5 over-expressing Arabidopsis plants under non-stress conditions, we compared the genome-wide expression profiles of Col-0 and plants over-expressing TaSK5 using DNA microarrays. Sixty seven genes were found to be expressed at least 2-fold more strongly in 35S:TaSK5 plants than in Col-0, and 17 genes were found to be expressed at least 2-fold more strongly in Col-0 than in 35S:TaSK5 plants. Most of the TaSK5 up-regulated genes were also induced by abiotic stresses, including cold, salt and drought. These results support the involvement of TaSK5 in abiotic stress signal transduction. Keywords: transgenic vs wt Col.-0 comparison

Keywords: transgenic vs wt Col.-0 comparison Total RNA was extracted from rosette leaves of two independent 3-week-old T1 Arabidopsis Col-0 plants over-expressing TaSK5 driven by 35S promoter and the whole transcriptome was compared with that of wild-type plant. Sample pairs in two independent transformants (OX7 and OX17), referred as biological replicates, were analyzed by the two-color method. Dye-swapped hybridizations were performed in every replicate.

Project description:The Arabidopsis thaliana NAC domain transcription factor, VASCULAR-RELATED NAC-DOMAIN7 (VND7), acts as a master regulator for differentiation of xylem vessels. In order to identify a set of genes regulated by VND7, we carried out a microarray experiment with the Arabidopsis full-genome GeneChip array ATH1 (Affymetrix) for transgenic Arabidopsis roots overexpressing VND7. Experiment Overall Design: Total RNAs were isolated from roots of 5-day-old seedling of transgenic plants overexpressing YFP and VND7-YFP under control of Cauliflower mosaic virus 35S promoter. Three independent biological replicates were performed for each sample.

Project description:We performed chloroplast ChIP-seq (cpChIP-seq) to identify the possible DNA-binding sites of mTERF5 in Arabidopsis thaliana. To this end, we generated transgenic Arabidopsis plants expressing mTERF5 carrying an HA tag under the control of the CaMV 35S promoter. Then, We used the polyclonal antibody (abcam, ab9110, lot GR304617-8 ) against HA tag which conjugated to ChIP-Grade protein A/G agarose (Thermo scientific, 26161, lot QJ223903) to perform cpChIP assay. The obtained chromatin immunoprecipitated DNA of chloroplasts were used to build DNA libaries for high-throughput sequencing. Finally, we showed that three potenssial DNA regions across the chloroplast genome compared to the control group were enriched by mTERF5.
