Project description:Transcriptional profiling of Arabidopsis thaliana 12-days old seedlings comparing Col-0 wild type with transgenic plants with altered expression of dual-targetting plastid/mitochondrial organellar RNA-polymerase RPOTmp. Transgenic plants used for experiment were: overexpressor plants obtained by transformation of Col-0 WT plants with genetic constructs created in [Tarasenko et al., 2016] contained catalytic part of RPOTmp enzyme with transit peptides of RPOTm (mitochondrial) and RPOTp (plastid) by agrobacterial transformation; plants with complementation of RPOTmp functions in mitochondria or chloroplasts obtained from transformation of GABI_286E07 rpotmp knockout-mutant plants with genetic constructs created in [Tarasenko et al., 2016]. Goal was to determine the effects of RPOTmp knockout/overexpression on global Arabidopsis thaliana gene expression.

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:Transcriptional profiling of Arabidopsis rossette leaves comparing WT Col-0 with a transgenic lines overexpressing AhNF-YC gene from Amaranthus hypochondriacus in three different conditions. Three-condition experiment WT vs AhNF-YC OE plant leaves. The analyzed conditions were: normal growth conditions, water stress for 5 days and 24 hrs of recovery after normal watering was reestablished to 8-day water stressed plants.

Project description:Transgenic Arabidopsis plants with constitutively low inositol (1,4,5) triphosphate exhibit an increased tolerance to water stress by an ABA-independent pathway The phosphoinositide pathway and inositol (1,4,5) trisphopsphate (InsP3) are implicated in plant responses to stress. In order to manipulate the pathway and determine the downstream consequences of altered InsP3-mediated signaling, we generated transgenic Arabidopsis plants expressing the mammalian type I inositol polyphosphate 5-phosphatase, an enzyme that specifically hydrolyzes the soluble inositol phosphates and terminates the signal. Transgenic plants have no morphological differences compared to wild type; however, rapid transient Ca2+ responses to a cold or salt stimulus are reduced by ~ 30%. To further understand the role of InsP3-mediated signaling in plant stress responses we focused on drought stress. Surprisingly, the InsP 5-ptase plants lose less water and exhibited an increased tolerance to drought. Stomatal bioassays showed that transgenic guard cells are less responsive to the inhibition of opening by ABA but show an increased sensitivity to ABA-induced closure. The onset of the drought stress is delayed in the transgenic plants and ABA levels did not increase as much as in the wild type. Transcript profiling has revealed that DREB2A and a subset of DREB2A regulated genes are basally up regulated in the InsP 5-ptase plants. These results indicate that the drought tolerance of the InsP 5-ptase plants is mediated in part via an ABA-independent pathway. The constitutive dampening of the InsP3 signal in this system has uncovered novel regulation and cross talk between signaling pathways. Keywords: drought stress, expression study

Project description:To decipher the role of cGMP during the hypersensitive response Arabidopsis thaliana transgenic lines have been produced which express a rat soluble guanylate cyclase. Transgenic plants display a higher constitutive amount of cGMP (4 to 50 fold) compared to wild-type. Both GC and wt genotypes were infected with PstAvrB and transcriptome profile was analyzed at 12 hours post-infection.

Project description:Comparison of wild-type and vip3. The Arabidopsis thaliana VERNALIZATION INDEPENDENCE (VIP) gene class has multiple functions in development, including repression of flowering through activation of MADS box gene FLC. Among VIP genes, VIP genes encode yeast Paf1 complex homolog which is required for histone modification, transcriptional elongation. To identify genes regulated by VIP3, we performed Affymetrix Arabidopsis gene chip analysis and compared gene transcription profiles from wild-type and vip3 mutant plants. We found more than 200 genes misregulated in vip3 mutant plants compring to wild-type plant. Keywords: Comparison of wild -type and vip3 mutants

Project description:In this study, we obtain FoAPY1 transgenic tomato plants (2417-GFP) and control plants (GFP). All target tomato plants were identified by WB using anti-GFP antibody and all transgenic tomato plants has no differences in morphological and growth rate compared with wild type tomato plants. In order to detect the potential functional mechanism of FoAPY1 protein in the host plant, the proteomic analysis was performed to analyze differentially abundant proteins in two type tomato plants
